This year is the "second five" to wrap, near the end, about the effectiveness of environmental protection, "second five" official statistics also have been released. Not long ago, Environment Minister Chen Jining in the "brilliant second five" special report at the meeting a series of reports on environmental protection and ecological civilization has made a presentation on the relevant data, can be seen from the minister Chen's speech, "Twelve five "environmental protection during the performance achieved is very prominent, four major pollutants - the chemical oxygen demand (COD), ammonia, sulfur dioxide and nitrogen oxide emissions are continuing sharp decline, has been completed six months ahead of the" Twelfth Five-Year significantly reduced the proportion of sections of major rivers in the inferior V class, down from 44% in 2001 to 9.0 percent in 2014, a drop of 80%;; "planning objectives focus on five heavy metal pollutants (lead, mercury, cadmium, chromium and category metal arsenic) total emissions decreased fifth more than in 2007, heavy metal pollution incidents decreased from 2010 to 2011 more than 10 cases per year to 2012 to 2014 average of three cases per year; in terms of widespread public concern on PM2.5 prevention and control work has made remarkable achievements in 2014, the first implementation of the new ambient air quality standard of 74 city average PM2.5 concentrations decreased by 11.1% over 2013. Relevant data and the list goes on. Progress data is one thing, but the true feelings are on the other hand. As a public one, it personally more concerned about is the various pollutants public data while lowering environmental quality personal experience whether it's improved. When ending the recall five years ago, "Eleventh Five-Year", even though the environmental conditions improve statistical data encouraging, but the public has generally reflect personal feelings about the quality of the environment has not changed significantly, and even the "Twelve Five "in the first quarter of the first year of high energy-consuming industries increased, the rise of pollution situation. The environmental achievement, "Twelve Five" period, the author's personal experience is the quality of the environment really improved, and it is clear! From January to August, the average concentration of PM2.5 in Beijing, Tianjin area and the same period in 2013 compared to 29 percent decline; Beijing standard number of days increased by 23 days, 22 days to reduce the heavy pollution days. Party and government attach great importance to environmental problems Environmental able to achieve such results, "Twelve Five" period, not unrelated to the party and government attaches great importance to ecological problems. Before the "five", we can not say the government does not pay attention to the ecological environment, but absolutely no mention of this level now. Understanding the concept of development, the relationship between economic development and environmental protection, the original understanding that environmental protection is necessary, not to engage in environmental protection, but if how to handle the relationship between the two economic development and environmental protection contradict us Understanding can be said that not firm. Even at the time of the issue of environmental protection laws is so understanding. 1989 enacted the old "Environmental Protection Law" in the first declaration of its legislative purpose of the relationship between economic development and environmental protection of the description is environmental protection "to promote the development of socialist modernization." Who assisted the Lord who, at a glance, this provision thus became the "pollution first, treatment later," an important legal basis. This year, the implementation of the newly revised "Environmental Protection Law" then it is clear that the legislative intent was "to promote the construction of ecological civilization, and promote sustainable economic and social development." Article IV of the Act also made clear that the purpose of the national policy on environmental protection is the "economic development and environmental protection coordination", even in the fifth article also proposed a "protection first" principle. Simple changes in legal provisions reflects the major party and the government on the development of innovative Notions, focusing reflected in the proposed "ecological civilization" concept. Ecological Civilization show the progress of civilization can not simply rely on to promote economic development indicators, the ecological environment itself and of the people's health are also an important part of civilization. Therefore, the ecological environment at the expense of economic growth can not be counted in exchange for the growth of civilization, good ecology is an important part of people's livelihood. Top-level design on the ecological environment damage liability lifelong accountability This concept of development of the performance concept of leading cadres have a decisive influence, and thus on environmental laws, formulation and implementation of policies to bring significant change. Third Plenary Session of the Party's eighteen proposed to "improve natural resources property rights system" and proposed to "explore the establishment of natural resources, the balance sheet, the implementation of the outgoing audit natural resource assets of leading cadres to establish ecological damage liability lifelong accountability system . "In other words, if a leading cadre in office only valued GDP and fiscal revenue growth and other economic indicators, while ignoring environmental problems, so he made the local economy of these" contributions "will not be recognized by the State, not only Leaders influence career advancement, there may be investigated by the party discipline. One of the important reasons of environmental enforcement is weak in some local governments the negative environmental aspects of the omission, in view of this, in the above understanding of the dominant ideas, August 9 this year, the CPC Central Committee and State Council jointly issued the " Leading Cadres of ecological damage to the environment of accountability (Trial) ", at the institutional level, the establishment of accountability mechanisms to recover the leadership cadres, so that leading cadres have a profound understanding of the importance of environmental protection. In this context, the Environmental Protection Department to interview some of the environmental protection ineffective local governments are mainly responsible for the growing importance of local party and government leaders. According to statistics, from January to August this year, the Environmental Protection Department has interviewed the main people responsible for 13 city governments, urging local governments and relevant units earnestly fulfill responsibilities of environmental protection, promote the settlement of a number of prominent environmental problems. Some very strict environmental laws and regulations escort It is also in this context, the recent years, China has developed a number of very strict environmental laws, regulations and policies. To amend the new "Environmental Protection Law" as an example. In addition to the legislative purpose of change described earlier, a major highlight of the "Environmental Protection Law" to modify the aggravation legal responsibility, for the first time provides for a "daily meter penalty" administrative detention strict administrative liability. According to statistics, the Ministry of Environmental Protection, this year from January to August, the nationwide implementation of the "daily count punishment" total 405 cases, fines of nearly 330 million yuan; the implementation of attachment, arrest a total of 2400 cases; the implementation of limited production, discontinued cases Total 1524. 2013 environmental protection departments at all levels to the public security organs criminal case transfer suspected contaminated totaled 706, more than the sum of the past decade. The environmental protection department in 2014 transferred to the public security organs suspected of environmental criminal cases reached 2,180, more than twice last year. January to August this year, the National transferring administrative detention cases since 1116, the transfer suspected criminal cases 1029 environmental pollution. Strict implementation of the new law, which greatly increases the cost and risk of environmental law, completely changed the original environmental law compliance costs are high, illegal low cost. In addition, the State Council also issued a very strict "Atmospheric Pollution Prevention Plan of Action" and "Water Pollution Prevention Plan of Action", made a total of 273 detailed air and water environment management measures, such an ambitious, detailed and strict pollution control plan in the world it is unprecedented. Environmental protection can promote industrial upgrading is a new opportunity for development Over the years, the state has been pushing for restructuring and elimination of backward production capacity of energy structure, but in practice the resistance continued. The biggest concern from people worried about after too strict implementation of environmental protection measures could bring economic stagnation or slow, so the country's environmental protection and industrial policy, there are always some local governments or enterprises sham. But this year has caused widespread concern people Linyi event to those who have concerns about environmental measures gives a clear answer: environmental protection helps industrial transformation, is to promote a new round of economic takeoff booster. Linyi past few years is taking the path of a typical urban development of extensive growth, bringing economic development environmental issues seriously, air quality has been hovering in the Shandong province a few. MEP disclosed interviewed Linyi municipal government is mainly responsible, called for strengthening the comprehensive improvement of air pollution. After the interviews, the Linyi municipal government set up by the mayor as head of the Leading Group for tackling air pollution control, take a series of measures to clean up the environment. After treatment, air quality in the first half of Linyi City weather 31 days more than last year, an increase of 25.4%, can be said to have been very significant environmental governance. However, after the implementation of control measures, there have been rumors in the community that the implementation of environmental protection measures to bring economic development of Linyi hit, unemployment seriously. But what the actual situation is? According to Minister Chen Jining introduction, this year from January to June, Linyi general public budget revenue totaled 16.13 billion yuan, an increase of 12.3%, higher than the average growth of Shandong Province (9.1%), the biggest increase among Shandong Province Section 3; 6.6 million new urban jobs, an increase of 12.2%, the registered urban unemployment rate 2.04%, less than 4% of the control objectives. Visible, although environmental protection will give extensive mode of economic development has brought pain, but the pains are necessary, otherwise sooner or later be a dead end; and environmental protection can promote industrial upgrading, this is a new opportunity for development. From the "five-second" environmental protection achievements, the statistical data pollutant emissions compared to most previous five-year plan and concluded that the environmental situation. Thus, we look forward to "Thirteen Five" period environmental protection can be obtained more exciting results. "Thirteen Five" period will show what kind of environmental protection situation? It can be seen from the foregoing analysis, the energy structure adjustment and industrial restructuring is a historical necessity, but it needs to pass many powerful Forced mechanism will be achieved. Environmental Management System "Twelve Five" period gradually straighten out, environmental management measures are maturing, increasingly stringent environmental enforcement, environmental liability stricter trend has been basically formed. These economic restructuring Forced mechanism will continue to play an important role in "Thirteen Five" period.

If you do not know how to choose central air conditioning water treatment agent, if you are concerned about product quality can not be guaranteed, if you have any other concerns, I will give you the answer! Specifically how to choose central air conditioning water treatment agent, and choose the central air conditioning water treatment agent needs attention to what matters, which in a later article, will give you more answers! First, central air conditioning, cleaning five steps: ① central air cleaning sterilization: through the circulation of water loop system central air conditioning added GJ- fungicide, remove central air conditioning circulating water, a variety of bacteria and algae. Central air conditioning system slime stripping, adding GJ efficient central air cleaning sterilization sludge remover, biological slime stripping central air conditioning duct shedding, by circulating the central air-conditioning duct cleaning out slime. ③ central air cleaning chemical addition to hard dirt: join central air conditioning running cleaning agents, dispersing agents, will rust central air-conditioning duct system, the hard dirt, oil cleaning down, dispersed discharge, reduction of clean metal surfaces. ④ central air-conditioning pre-film surface: put GJ central air conditioning pre-film agent, central air conditioning metal surfaces to form a dense protective film polymeric polymer to act as anti-corrosion effect. ⑤ central air conditioning water treatment routine maintenance: inhibitor dosing, avoid metal rusting, while adding inhibitors, through comprehensive action to prevent the precipitation of calcium and magnesium ions crystallize. And regular sample testing, monitoring water quality. Second, central air conditioning water treatment after the cleaning effect: ① protect the central air-conditioning equipment, extend the service life of the central air-conditioning: Rust can, avoid the central air-conditioning equipment corrosion damage, especially after the central air-conditioning cleaning preventive treatment to extend the life of the central air-conditioning equipment, corrosion inhibitors can put Central Air conditioning corrosion rate dropped 90 percent. ② reduce central air accidents, improve the central air conditioning and refrigeration effects: sterilization, removal of sludge, the central air-conditioning duct flow, the water is clear, at the same time scale, improve the heat exchange efficiency of the central air-conditioning condenser, evaporator, thus avoiding high voltage operation, ultra downtime, improve the flow of chilled water central air-conditioning, central air-conditioning cooling effect to improve, the central air conditioning system safe and efficient operation. ③ saving electricity and water and fuel savings: remove scale and prevent the formation of scale, improve heat exchange efficiency central air conditioning, thereby reducing energy and fuel consumption, and central air conditioning water treatment can also reduce emissions, thereby improving the central air conditioning circulating water use rates, generally more than 60% water saving. ④ for users save a lot of maintenance costs: the cleaning process without central air conditioning, pipe blockage occurs, scaling, corrosion, overpressure shutdown until the accident, such as central air conditioner leak due to corrosion, pollution solution, you need to replace brass Replace solution, central air conditioner repair, maintenance normally takes 20 to 50 million, while after the cleaning process, can reduce maintenance costs, and extend the life of the central air-conditioning equipment, but also for the owners to reduce the hundreds of thousands or even hundreds of Millions of loss.
Circulating cooling water is circulating cooling water refers to the exchange medium heat and, after cooling tower cold water, recycling of heat exchange or direct contact heat transfer through the heat exchanger to save water resources. A circulating cooling water system to be cleaned, pre-film program and daily operational relationship between the three, which is experiencing the longest daily running of a stage. Under normal circumstances, the recycled water is neutral and alkaline, pH value is usually controlled in circulating cooling water acidic or alkaline (pH value greater than 10.0) between 7-9.5 in the case of direct contact with the media, general less. As time goes by circulating cooling water, constantly replenish water into the cooling water system. At this point, add some water and half a combination of CO2 escape into the atmosphere and lost, so that the cooling water ions lose their balance, causing the circulating water scaling, this is to reduce the carbon dioxide content of lead. With the circulating cooling water evaporation, cooling water hardness and alkalinity will rise, when the water is concentrated supplement N times, circulating cooling water hardness and alkalinity increase along with the concentration ratio of the increase in direct proportion. With the growth of concentration, turbidity in the water also will be increased. Circulating cooling water in the cooling tower painting process, a lot of oxygen in the air into the water, leading to increased amount of dissolved oxygen, an increase of caustic circulating cooling water system The process described above is the basic situation circulating cooling water system will encounter, this time, water treatment chemicals can be a good inhibition of the formation of scale and oxygen, water treatment chemicals have oxygen scavenger and corrosion inhibitors, corrosion resistance detergents in it is not a single product, unlike ATMP, HEDP, EDTMPS, HPMA, PBTCA, PAA, and other products have a single monomer synthesis preparation, corrosion and scale inhibitor mechanism is divided into: lattice distortion, and increase network Rong, such as the use of electrostatic repulsion. Corrosion Inhibitor is a great cause of water treatment agent, water treatment agent can be divided into eight categories: scale dispersant, corrosion inhibitor, corrosion inhibitor (corrosion inhibitor), biocides, flocculation agents, cleaning agents, pre-film and other agents.
