Due to impurities in the water more amazing scaling it up fast. There are many types of corrosion and scale inhibitors, which are designed for use in industrial circulating water systems such as power plants, steel mills, chemical plants, oil field water systems. Fouling of water quality special corrosion inhibitors is a versatile all-organic hybrid water treatment agent. This drug has a high temperature, difficult to hydrolysis, strong anti-oxidant properties of features, which makes it suitable for high hardness, high alkali, high temperature, high PH circulating cooling water. The agent is not higher chloride and ferric ion impact, its use concentration is generally 50-70mg / L, do not adjust PH, simple operation, easy management. Various characteristics of corrosion and scale inhibitors with higher adaptive capacity, making it suitable for a very wide range. These make it possible to have a good use of the market, and has a high market value.
Number of industrial fungicide medication should be appropriate, reasonable configuration is more conducive to concentration bactericide effective. If arbitrary ratio, high concentrations will cause crop injury; concentration is too low reach prevention requirements. Number of fungicides including drug quality drugs, the number of drugs and spraying quality. Too much medication increase costs and cause injury, industrial water treatment agent fungicide according to sterilization mechanism can be divided into oxidizing and non-oxidizing biocide bactericide two categories. Too little and reach Prevention result, whether it is a liquid or wettable powder drugs are necessary dilution of the water before the spray fungicide use concentration differences have requested, Therefore, to be held in strict proportion with the book and listen to illustrate the need to hold increased or decreased depending on the environment, now commonly used in oxidizing biocides have chlorine, chlorine dioxide, bromine, ozone, hydrogen peroxide and the like. Common non-oxidizing biocides have chlorophenols, isothiazolin-ketone, quaternary ammonium salts. Visualization number of drugs and drug Vinca depending on weather conditions, such as rain after application. Therefore non-oxidizing biocide agents induced effects on particular parts of the essentials of microorganisms, oxidizing biocides generally strong oxidant, tension resolved with bacterial metabolic enzymes produced by oxidation of reach sterilization purposes.
Industrial circulating water treatment chemicals for industrial water, wastewater treatment chemicals required in the process, through the use of these chemicals, the water can reach the necessary quality requirements. Its primary effect is to control scale and sludge composition, cut foam, reduce erosion and water contact information to remove suspended solids in water and toxic substances, soften water, deodorant decolorization. Due to a sharp increase in the current world of water, various environmental statutes (water purification method) one after another to develop and increasingly demanding, so efficient on all types of water treatment chemicals promotional quickly. In China, the water crisis is the contradiction of water treatment chemicals production capacity is very low, the quality is not guaranteed, so the acceleration of water treatment chemicals that carry out environmental data property is imminent. So the study type and characteristics of industrial water treatment agent is very important. Our water treatment chemicals is the introduction of large chemical fertilizer plant in the 1970s after the attention and gradually developed; thereafter, self-developed a series of water treatment agent. Variety of industrial circulating water treatment chemicals mainly scale inhibitors, corrosion inhibitors, biocide agents, inorganic coagulant (PAC, polyacrylamide), organic flocculants and other categories biocide (water treatment fungicide), cleaning agents, slime stripping agent, flocculants (PAC, polyacrylamide), coagulant, dispersant water treatment chemicals, sodium hexametaphosphate is also a water treatment. PAC and with the use of modified cationic polyacrylamide, coagulation sedimentation Filtration by waste water, with very good treatment effect. Modified cationic polyacrylamide molecular weight is not too high, and with the PAC easily composite to achieve the desired effect.
1, the current situation of urban water supply By the end of 2014 China has 750 cities officially, 1,818 counties, 26,001 towns. By the end of 2014, the number of national public water supply plant has nearly twenty thousand, of which there are 6,001 counties, the town has 16 008; water supply capacity of 530 million cubic meters / day; the total annual supply of 86.8 billion cubic meters; from water penetration, the city, county and town, respectively 97.6%, 88.1% and 81.7%; urban public water supply coverage was 91.7 percent, the county was 82.5%; public water supply pipe network leakage rate of towns is still relatively high, city 15.5%, 13.6% county. 2, the current situation of urban sewage treatment Treatment of urban waste water from the status quo, as of the end of 2014, there were 5,300 sewage treatment plants, sewage treatment capacity of 163 million cubic meters / day, sewage treatment capacity of 45 billion cubic meters has been reached, resulting in the amount of wet sludge There are 30 million tons; sewage treatment rate of the city and county have already reached 89% and 78%; urban centralized sewage treatment rate reached 85 percent, the county's centralized sewage treatment rate reached 76%; urban sewage treatment for national energy conservation The contribution rate, from 2013, the annual reduction in the amount of COD and NH3-N, respectively, to reach 11.2 million tons and 100 million tons. From the current emission standards for the country's urban sewage treatment execution, we mainly do is level B standard, by size to statistics, nearly 50 percent of the sewage treatment plant are performing a level B standard, 25 percent of the sewage treatment plant the implementation of an A standard, and nearly 25 percent of the wastewater treatment plant are performing a secondary standard, in addition to some of the wastewater treatment plant is to reach four types of environmental standards for surface water, the standard is very high. From sludge treatment and disposal, the current or most of our sludge to landfill mainly into organic fertilizer, building materials and engineering backfill sludge rare. The disposal and resource recycling, harmless sludge we have a lot of work to do, which is key direction "five" and the next "Thirteen Five" work.
Water has been the focus of the industry. The reality is that pollution, corrosion and scale inhibitors had to use, corrosion and scale inhibitors as a new water treatment agent, has been around for years. Corrosion Inhibitor types of corrosion inhibitors. Non-phosphorus corrosion inhibitor to strengthen environmental protection. Let us make efforts to improve the environment, so this market forward. A high-quality product is a service, good service everyone will be satisfied, in order to promote industrial progress, we are the only produce a good product. The implementation of standards in accordance with Corrosion Inhibitor Corrosion inhibitor is added in an amount, it will play a very good effect, but in this one should pay attention to the following surveying inhibitor must pay attention to. In the process of re-use is a major change in the effect of water quality, if salt water very much, this is to let the action slows down, so you can control the salt content in the water to improve the high-hardness water Corrosion Inhibitor role of strength. Temperature is also one of the reasons reagent, for decreasing the viscosity, of the increase in temperature can be a little. Reverse osmosis unit, there will be a concentration is not the same, this will change the whole system work. Since the refinery is one of scale by generating more places, corrosion and scale inhibitor refinery plant in the severe accumulation of dirt quickly cleared.
As a corrosion inhibitor manufacturers of our products can prevent fouling and corrosion phenomena appear successful to reduce water hardness, which can help extend the useful life of equipment, the premise is to ensure correct use. As we scale and corrosion inhibitor manufacturers to remind you: in circulating water use, according to a certain ratio to operate, so adding the appropriate water treatment agent can be placed. But beware of sewage treatment in a timely manner, usually every hour the sewage processing, control time in about 10 seconds, if a lot of dirt appear, dosage should be increased, will accelerate the use of frequency, using about half You can stop equipment operation, the use of artificial dirt off, to prevent clogging of the pipeline phenomenon, affecting the normal operation of the equipment. Note that water treatment agent should use plastic water tanks, pools embalmed to do otherwise would be corrosion agent, so the hardness increases.
The current production of water treatment chemicals lot, but have no uniform standard, only the individual enterprise standards and test reports, which both supply and demand on the quality of the product, there is no uniform legal discrimination basis. Although the process produced various enterprises water treatment chemicals and raw materials used are different, and the control of the technical indicators are also different, but solvent-based water treatment chemicals common to several important technical indicators should be consistent, which facilitates Use the Find problems. The following will be discussed in several technical standards. First, acidity Any type of water treatment chemicals for pH are the technical specifications must be strictly controlled. Especially solvent-based water treatment chemicals, acidity index is more important, because the cleaning is finished workpiece, mostly without any treatment, the quality of water treatment chemicals, and a direct impact on the quality of the workpiece cleaning. So acidity index represents the stability of water treatment chemicals and cleaning of the workpiece quality assurance. Such as the current fluorocarbon, chlorine hydrocarbons, bromine hydrocarbons, hydrocarbons and alcohols and other water treatment chemicals on the market for use in the production process must be strictly controlled acidity, while the change in order to prevent the occurrence of storage and use, must be at the factory When the addition of various stabilizers and antioxidants make it stable, to prevent decomposition in the use and heating. Because these substances decomposition of acidic substances such as HF, HCL and HBr, etc., in the face of trace water becomes acid, after increasing acidity, not only for the cleaning of the workpiece impact, the metal surface and dull, damaged components; and In the long-term effects of acidic medium, stainless steel equipment will be corroded. So the above water treatment chemicals have added stabilizer. If you select a stabilizer amount of bad or insufficient, water treatment chemicals in repeated contact with the heating and air will occur or produce acidity increased oxidative decomposition, water quality deterioration of the medicine, leading to corrosion of the workpiece and so on. Stabilizers or antioxidants usually factory added the following categories: phenols, alcohols and epoxy compounds, etc., the added amount is generally less than 0.05% to 5%. Acidity factory control 10ppm (0.001%) within. Acidity testing is conducted according to the provisions of GB4120.3, it is equivalent to the international standard ISO-1393, using acid-base titration. Since many water treatment chemicals insoluble in water, can not be titrated with lye, instead of using the washing method, titration solvent wash water treatment chemicals from water liquid down. This method is more cumbersome. Ethanol lye can also be used to direct titration method, because a lot of water treatment chemicals are dissolved or partially dissolved in ethanol. This method is simple, reliable, easy to plant testing. Second, water Solvent-based water treatment chemicals water content is also very important indicator, Sheung Shui principles better, but a lot of production and use can not be completely dry, but each solvent and has a certain moisture content. Some completely miscible with water, such as lower alcohols, ketones and ethers portion; some at a certain temperature has a certain saturation solubility, such as hydrocarbons, fluorocarbons, hydrocarbons and chlorine bromine hydrocarbons, moisture exceeding the saturation solubility, delamination occurs, and the solvent stabilizer pumped to the water layer, so that the stability of the solvent water treatment chemicals deteriorate. At the same time the presence of water, water treatment chemicals in free Fˉ, Clˉ and Brˉ ion with water to form acid, creating a vicious cycle in heating use, the acidity is getting higher. Therefore, the acidity of water treatment chemicals and water are the two interdependent indicators directly affects the quality of the cleaning of the workpiece. If the workpiece after cleaning, tarnish or leave watermarks on the workpiece, just like acidity and moisture related. Current domestic production of solvent-based water treatment chemicals, moisture control in 100ppm (0.01%) or less. Trace moisture carried by the provisions of GB6283-86. That Karl Fischer method. Cloud point may also be a simple method, that according to the provisions of GB4120 conduct. It can also be used to analyze gas chromatography. Three, non-volatile matter (residue) The number of water treatment chemicals in non-volatile matter content, directly affect the cleanliness of cleaning the workpiece. Since the cleaning workpiece is immersed in the cleaning solution, then let it dry, then wash liquid non-volatile content may be directly adhered to the workpiece. If electronic components, will affect its electrical properties, in particular the PCB like microcircuit devices attached to the board based on the number of ions per square centimeter much μg (NaClμgcm2) meter, requiring low as possible, the general factory control below 10ppm. This is based on domestic and foreign production of a single solvent-based water treatment chemicals business standards. Its detection method prescribed GB6324.2-86 of conduct. The method is similar to ISO759-1981 of. A simple detection method is to drop the number of drops of water on a glass lens processing agent, let the natural evaporation, watch residual traces on the lens, it can roughly determine the amount of non-volatile water treatment chemicals. Of course this is only qualitative testing. Fourth, toxicity Toxicity is an important indicator of whether the use of water treatment chemicals. Although it has no direct impact on the cleaning of the workpiece, but for humans and the environment has a profound impact, but also our choice whether it's a major factor today. Toxicity of water treatment chemicals, are identified in animal experiments and related infrastructure on human physiology experiments. Strictly speaking, any chemicals are toxic, but the size of the other. The size of the toxicity and safety of human range and take preventive measures, only come through strict animal experiments. Per kilogram of body weight of the animal can withstand the measure. While many chemicals predecessors have done experiments related toxicity is well documented, but now is not the pure water treatment chemicals, data may be available for reference on. The mixture is only through real animal experiments to determine safe concentration range for producers and users to establish a secure protection measures and precautions. Toxicological experiments mainly by two experimental oral and inhalation. The amount of rat LD50 acute oral toxicity test, ie semi-lethal dose, the lower the toxicity; the same amount of rat acute inhalation LD50, the greater that is half the lethal dose, the workpiece environmental allowable concentration higher. According to these measured data, you can develop safety standards and precautions that water treatment chemicals workpiece sites. Toxicological experiments by preventive health sector. According to the provisions of GB5044-85 GB1560-1995 or conduct and pricing. These are discussions on several important indicators common solvent-based water treatment chemicals carried out. Of course, there are many technical indicators of water treatment chemicals, such as insulation, swelling of the material, flammable, volatile, KB value and other technical indicators, because of different cleaning objects vary. But the above four points are common important indicator each water treatment chemicals manufacturer should be considered.
The new scale inhibitors have a good bactericidal effect, our understanding of the scale inhibitor is its unique ion for the formation of scale can play water dispersion inhibition, scale inhibitor introduced chlorine atoms in the molecular structure of phenol, making resistance detergents has a good bactericidal effect, as well as a good deodorant degreasing effect, our main content today is for everyone to explain the application of the principles ANTISCALANT: The main effect of inhibitor is to prevent fouling, but the domestic market is highly competitive, inhibitor manufacturers to respond to the needs of users are in the research and development of a variety of features as one of the new water treatment product, has bactericidal barrier detergents products is worthy of our attention, in fact, the reason is very simple, we kill the algae, fungi through biological principles in order to achieve the elimination of the circulating water system, bacteria and algae problem is very common, need Efficient sterilization processing, due to the molecular structure of phenol introduced chlorine atom, its sterilization ability is improved, the compound is not easy to break down bacteria and algae, aquatic organisms and mammals have damage, so contamination issues must attract enough attention. Compatible with most water quality stabilizer and water treatment agent chemicals, scale inhibitors can be in a wide range of PH value use, and small fish such as toxicity, readily biodegradable, less environmental pollution, etc. . A wide range of applications in which a quaternary ammonium salt and typical. Inhibitor in oxygenated water flow while enabling a closed channel, played the role of aeration and agitation. Both to improve product quality, and reducing costs, but also greatly extend product shelf life, and water recycling and water usage continues occasion.
"Currently there are 40,000 large and small environmental companies, the future market does not need so much, you may only need 500 to 1000 outstanding companies." E20 platform environment chief partner Fu Tao said recently that the next 5 to 10 , the environmental protection industry will usher in profound industrial reconstruction period. His company has officially register a new three-panel, environmental protection industry has become the first unit depth platform. For deep remodeling industry, on the one hand to open up new areas included, on the other hand it is industry mergers and acquisitions. He said that the environmental protection industry is currently very serious industrial mismatch. There are a lot of vicious competition in the business model mature field, and in large areas of demand but not mature, enterprises are a lot of vacancy. Prospects for future development where every competitive enterprises must consider. In this regard, Sander Group Chairman Wen Yibo also very much agree with: "Now we are in something that looks relatively large space for development, but in fact a relatively narrow field of competition, even vicious competition we play in life and death, a lot. people think the industry is so. And I think the environmental protection industry is large enough, there is enough for everyone to do things, there is also a lot of blue ocean industry worth to try. I think the industry's leading companies, and now the big companies, should set an example. " According to him, Sander layout two Internet sanitation infrastructure has been initially formed last year income of 80 million yuan, more than 400 million yuan this year, next year is expected to reach 15 to 20 billion. "I think we found a blue ocean environmental protection industry. Similar segments are still many areas of environmental protection, such as industrial areas. With the strengthening of environmental regulation, real excellent technology, products and services, as well as the vast space." The past two years, the environmental protection industry giants increasingly rapid pace of expansion, if only large enterprises living space in the future? In this regard, Fu Tao said, for now, it has formed various environmental segments of competitive enterprises, should be seen as a very valuable industry resources, and even has the real estate properties, is cross-border pedal, is the integration of object. "As long as you are the best, it will be recognized capital market."
April 19, 2012, the State Council issued (('' second five "national urban sewage treatment and recycling facilities construction plan" (SCS [2012) 24). Planning, pointed out that "five" period urban planning within the scope of the national scale of new sewage treatment 4,569 million cu m / day in which cities officially 2,608 million cu m / day, the county 1,006 million cu m / day, towns 9,550,000 m3 / day; Eastern Region 1,898 million cu m / day, the central region of 1,477 million cu m / day, 1,194 ten thousand cubic meters of the old western region. After the completion, all cities have sewage treatment plants were built, every county has a sewage treatment capacity, the provinces (autonomous regions, City) sewage treatment rate reached planning to determine the objectives, to enhance the national sewerage services. April 2, 2015, the State Council promulgated the "Water Pollution Prevention Plan of Action" (Guo Fa [2015) on the 17th). Program notes that "speed up the construction of urban sewage treatment facilities and reconstruction existing urban sewage treatment facilities, to transform local conditions, to achieve the appropriate emission standards or recycling requirements before the end of 2020. Sensitive area (emphasis lakes, focusing on reservoirs, coastal waters sinks water area) urban sewage treatment facilities shall, before the end of 2017 to achieve a comprehensive level A emissions standard. built-up area of ​​water quality of surface water can not reach the standard IV class city, the new urban sewage treatment facilities to perform an A emission standards. By Country new town planning requirements, by 2020, all the country's counties and key towns have wastewater collection and treatment capacity, county, urban sewage treatment rate reached 85%, respectively, about 95%. Beijing, Tianjin, the Yangtze River Delta, Pearl River Delta and other areas ahead of a completed. " Meanwhile, with the continuous development of sewage treatment industry, the state of urban sewage treatment plant emission standards becoming more stringent, according to the country but also the strict implementation of the new standards, the discharge standards for wastewater treatment technology to enhance the proposed higher requirements. "" Second five "national urban sewage treatment and recycling facilities construction plan" (SCS [201 quotes 24) made on the part of the construction of sewage treatment facilities have been upgraded to further enhance the ability of major pollutants reduction. Lack of phosphorus and nitrogen removal function vigorously transformation, do not have the biological treatment capacity of sewage treatment plants, focusing on the transformation of domestic waste and developed areas, key watersheds and water sources and other important areas of sensitive water sewage treatment plant. "Twelve Five" period, the urban upgrade within the scope of the transformation of the National Planning 2,611 ten thousand cubic meters of sewage treatment capacity of the old. Among them, the cities officially 2,038 ten thousand cubic meters of the old, old town 5.27 million cubic meters, 460,000 cubic meters of the old towns; 7.94 million cubic meters of the old eastern region, the central region of 1,318 ten thousand cubic meters of the old, old western region 4.99 million cubic meters. This trend led to the development of water treatment agent industry.
