 into the hall of the Haining municipal government office building, a huge "Haining five water co operation" battle map is presented to the reporter's eyes. "Five water co governance" is like five fingers. Sewage treatment is the thumb, putting the first place; flood prevention, drainage, water supply, water conservation and water saving are the other four points. Division of labor is different, harmony and difference, and pinching up will form a fist. Chen Hongming, deputy director of Haining Environmental Protection Bureau, told China Leather net reporter that "five water co governance" is a large-scale water control operation carried out by Zhejiang Province, of which "pollution control" is the first. 
 "Haining tannery sewage treatment is implemented earlier and requires high; Haining has long stipulated that industrial enterprises can not use underground water, so we take the protection of water resources as an important policy to implement." Chen Hongming said that as early as 2010, the environmental protection verification carried out by the Ministry of environmental protection in Haining was implemented in the 11 implementing rules of total emission reduction and total quantity control of major pollutants, requiring tannery enterprises to carry out self-examination to meet all environmental requirements. 
 Chen Hongming introduced that in the following years, Haining insisted on improving the quality of the fittest and promoting the strict management of the standards, and actively encouraged the support of qualified large enterprises with conditional management, and eliminated the shoddy small businesses that were unable to manage. After several years of renovation, the tannery industry in the city has been reduced from 38 to 8, and most tanneries have been concentrated in industrial parks. 
 January 1, 2013, according to the guidance issued by the Zhejiang provincial government on the promotion and improvement of heavy pollution and high energy consuming industries in 12th Five-Year, the Zhejiang provincial environmental protection department and the Zhejiang economic and Information Committee jointly issued the notice on printing and dyeing, paper making, leather making, chemical industry and other industries. The Haining Environmental Protection Bureau, in combination with the actual situation of the local area, deployed heavy pollution and high energy consuming industries to upgrade and upgrade, also known as the "zero action". The action passed 64 acceptance criteria such as "three wastes" treatment, and plans to use the whole year to upgrade tanning enterprises. 
 "the government attaches importance to, the association matches, the enterprise diligently, forms the environmental protection linkage effect." Gong Huihong, Executive Deputy Secretary General of Haining Leather Industry Association, said that the Haining municipal government attached great importance to leather making and environmental protection. Tanning enterprises were also very active. In last year's "zero action", 8 tanning enterprises all passed the inspection. At present, the government and associations have implemented the most stringent environmental management measures for the 8 tannery enterprises that have been retained. All of them have implemented rectification in accordance with the requirements of benchmarking enterprises. 
 in the strict management of enterprises, Chen Hongming also introduced relevant policies to encourage tannery enterprises to promote the healthy development of enterprises. The implementation measures of Haining industrial enterprises' evaluation and evaluation of mu yield efficiency is one of them being implemented. "Haining" 
 according to Shen Qing, deputy director of Haining economic and Information Bureau, the evaluation method of "mu yield benefit" has been implemented since last year. The evaluation method is to carry out comprehensive evaluation of Enterprises above Designated Size in the city through the evaluation system set up by taxation, output value, labor productivity, environmental protection and other indicators, and carry out the pilot work of comprehensive supporting reform of environmental resources allocation. 
 Shen Qing further stated that the "mu yield benefit" is a comprehensive evaluation of the implementation of pollution discharge, including enterprises. The ranking enterprises are "forced" to spanform and develop enterprises by means of law, economy and administration. The evaluation method also carries out the differential approval of the annual permitted emissions of enterprises, starts the paid use and spanaction of ammonia nitrogen and nitrogen oxides, and substantially increases the paid use and spanaction price of the emission rights index in heavy polluting industries, implements differential emission reduction assessment policy and differential water price, and improves the water consumption cost of heavy polluting enterprises. 
 "by deepening the environmental protection mechanism, we have further accelerated the spanformation and upgrading process of polluting industries such as leather making." Shen Qing said. 
 Enterprise Initiative < a href= "http:// www.91se91.com/news/index_c.asp" > tannery environmental protection < /a > become conscious action /p >
 perfect policy system is a powerful guarantee to guide the healthy development of tanning enterprises, but the most important thing is the strict implementation of tanning enterprises. "As long as the government introduces new policies, we will implement them." Zhou Yonggen, chairman of Haining Fusheng fur and leather Co., Ltd. (hereinafter referred to as "Fu Sheng fur leather"). 
 referring to environmental protection policy, Zhou Yonggen took out a few thick papers from his desk. "This is all about environmental protection policies. We are all learning. Doing environmental protection well has become a conscious action of enterprises." Here we are not only referring to the fur raising, but also represent the 8 leather making enterprises in Haining, such as Haining brothers leather Co., Ltd. (hereinafter referred to as "brother leather") and Zhejiang Fu Di Agriculture Co., Ltd. (hereinafter referred to as "Fu Di agriculture"). In an interview with reporters, this is deeply felt. 
 "tanning enterprises in Haining, every boss is an expert in environmental protection, and environmental protection has risen to the" leader "project. Gong Huihong said, "the first thing that the boss pays attention to is not order, but the situation of sewage disposal. Every day, the environmental monitoring results should be sent to the main person in charge of the enterprise in time by SMS or WeChat." On the walls of the office of Zhou Yonggen, chairman of the office of Fu Sheng, Chairman Mao, 9 small screens are switching at regular intervals. Each picture shows different factory workshops, but there is one thing in common -- neatness. 
 according to the introduction, the monitor can keep track of the tanning workshop at any time, including the discharge status of the sewage. Zhou Yonggen said, "environmental protection water treatment spanformation is 5 years ago, and now Haining has risen to the disposal of hazardous waste, waste materials, garbage and odor." 
 in the Fu Sheng leather leather workshop, the reporters saw that the sewage before tanning and chrome tanning were collected and processed separately. In the treatment of chromium containing sewage, chromium water is collected and sent into the separation tank to produce chromium mud after separation and precipitation, and then the chromium mud is precipitated into chromium cake. 
 in the workshop, the reporter saw the packing paper neatly labeled with the kraft paper bag. Zhou Yonggen pointed to the bag and said, "here is the chromium cake. It belongs to the hazardous waste material. How many chromium cakes are produced in the workshop every day, which company should be sent to the company to deal with, it should be reported to the Zhejiang provincial environmental protection department's hazardous waste treatment platform, and there must be no mistake. The professional hazardous waste treatment company received chromium cake processing, such as deep processing to make chrome powder, which can be used by tanning enterprises again, achieving a win-win situation between hazardous waste management companies and tanning enterprises. At present, the whole leather making enterprise in Haining is promoting this way. " 
 in the Fu Sheng fur workshop, a reporter's attention has been paid to the faucet spray equipment above the leather conveyor belt. "This is a new technology developed by Zhou Yonggen himself. This technology not only saves water but also saves electricity. In the Fu Sheng, this "small business" is nothing new. Every time we come to the workshop, we can see a new technology developed by him. Gong Huihong said. 
 Gong Huihong said Zhou Yonggen is an expert, but he mocked himself as "sewage station master". It is understood that Zhou Yonggen's research and development of technology and equipment not only for their own use, but also to other tannery enterprises, "sometimes tanning enterprises in the field to learn, Zhou also did not retain the introduction of new technologies to these brotherhood." Gong Huihong said. 
 in Haining, the upgrading of leather making environment is always carried out in a regional form. In the case of brother leather, journalists visited the entire sewage treatment equipment with relevant personnel. "Our sewage treatment facilities and technologies are superior to those of some advanced countries." General manager Qian Zhiming said. Reporters who had visited the sewage treatment facilities of tanning powers agreed. 
 in the interview, the reporter found that there was a set of data on Qian Zhiming's mobile phone. The reporter went over to see the data above, which reads "4.27 of the rainwater and 3.38 of the discharge water". Qian Zhiming said that he and his environmental protection team receive regular messages from the environmental laboratory every day, and monitor the status of environmental pollution at any time and place. If there is any abnormal situation, we should start the emergency plan immediately. 
 in agriculture, environmental protection laboratory plays an important role. In the lab, the reporter saw a set of water quality automatic monitoring and control system, showing the data "COD is 123.61mg/L, total chromium 0.044mg/L". According to Pan Shaojie, general manager of Fu Di agriculture, the laboratory adopts the third party monitoring mode to ensure the authority and accuracy of data. 
 he said that the tannery pollution in the past was more serious, and there were more sewage in the workshop. Last year, the boss asked to meet the standards for improvement and upgrading. "Bad management is gone." next week, a meeting was held to report all kinds of progress. Nowadays, journalists wear sandals to walk in the workshop. In addition, the chrome free tanning in Fu Di agriculture now accounts for 80% of the total output. This "green" tanning method greatly reduces the environmental pollution of heavy metals. 
 Pan Shaojie introduced that part of foreign equipment was selected for agricultural environmental protection in Fu Di, with a total investment of more than 3700 yuan. The leather enterprises of Fu Sheng leather and brother leather have invested 30 million yuan and 130 million yuan in environmental protection construction and industrial upgrading, respectively.

 interview, the reporter learned that part of the investment in environmental protection of enterprises is used in upgrading and upgrading of process equipment. The photocatalyst equipment used by Fu Sheng leather has invested more than 100 yuan, which is recommended by Professor Lan Yunjun of Wenzhou University. The equipment can achieve good results in leather cleaning and deodorization. In Haining, the agriculture in Fu land is also used. 
In the three leather making enterprises interviewed by P, whether they are rich fur or leather, or Haining agriculture, they mentioned the leather technology research and development institutes of the leather research institute more than once. They said that these leather professional research institutes played an important role in helping enterprises to improve environmental technology and technology. 
 "we are developing technology according to the requirements of tanning enterprises for solving problems of enterprises." Sun Haobin, Dean of Haining Leather Research Institute, said in an interview with reporters. In Haining, there are multiple innovative carriers and organizations to provide timely and thoughtful scientific and technological innovation services to leather enterprises, and solve the problems raised by enterprises in a timely manner. These include the Zhejiang leather cleaner production technology innovation alliance, led by the Haining Leather Research Institute, the Key Laboratory of Zhejiang Leather Engineering led by Wenzhou University and the technological innovation service platform of Zhejiang leather industry, the Haining leather products economic spanformation and upgrading service group, and the academician of Shi Bi academician, Wenzhou University, Zhejiang province academician expert workstation, which has been listed as a typical academician of Zhejiang province. 
 "we are doing things that the government needs, the industry is concerned about, and the business is welcome." Lan Yunjun told reporters on China Leather net that he basically went to tannery enterprises with the leather industry association of Haining every week to understand the needs of enterprises and to improve and optimize projects after using new technologies. He said that the technologies developed by Wenzhou University, such as water saving, chrome free tanning and hazardous waste disposal, are also in good contact with enterprises. 
 in water saving technology, Sun Haobin introduced the largest amount of water used in fur tanning. The Haining Leather Research Institute introduced Spanish technology since 2007. In the process of domestic use, the technology needs to improve the production equipment with drum as the core. No matter tanning or shedding, it can be more efficient and greatly reduce water consumption. Now the technology is used not only in fur, but also in leather. 
 in the process of producing tanning, water saving technology is not only that, LAN Yun Jun said, water saving can be achieved through reclaimed water and reduction technology. He said that some water can be recycled and used again, while some dispensable processes have been reduced and the water consumption has been reduced. In the interview, water saving is often heard by journalists, and the other is the separation of chromium and water, and the separated water is recycled again. 
 for chromium treatment, according to Sun Haobin, there are two ways of high chrome tanning and chrome free tanning. High absorption chrome tanning can increase the absorption of chromium by adding special additives in chrome tanning process. For chrome free tanning technology, LAN Yun Jun said there are four or five kinds of technologies. Among them, Wenzhou University mainly studies starch free chrome tanning agents, non chrome metals such as zirconium, titanium and aluminum compound tanning agents and their special auxiliary tanning technology. 
 Sun Haobin said that when studying chrome free tanning technology, it encountered two problems: high cost and low leather shrinkage temperature. After many experiments, these two problems were solved or improved. For the chromium sludge produced by chrome tanning, the Haining Leather Research Institute is studying how to make tannery sludge harmless resource utilization. 
 Sun Haobin introduced that the Institute is experimenting with a subcritical hydrothermal reaction technology, which can make the sludge produced by Haining leather tanning reach 600ppm or even below. However, the technology requires higher equipment and can solve the difficulties of enterprises through centralized treatment, which will ultimately greatly reduce the cost of solid waste disposal. "The technology is expected to see primary results in the second half of next year." Sun Haobin said. 
 in fact, the pollution of leather making process can be effectively controlled by cleaner production technology, for example, the use of micro enzyme and wool removal technology can be used in cowhide. Lan Yunjun said that ordinary technology will destroy cattle hair into the waste water into COD and ammonia nitrogen, while increasing the amount of sludge. The use of hair removal and hair removal technology can save the wool, do not enter the sewage, COD and ammonia emissions can be reduced by more than 50%, the amount of sulphide alkali will also be reduced to 1/3 of the original. 
How can we get rid of the hair of P? "Burning will stink. It can degrade hair into water-soluble keratin material and directly apply to leather filling process." Lan Yunjun said that this technology is known as "wool hair removal and recycling of cow hair to control the preparation of leather filler". At present, the cooperation between Haining's agriculture and Wenzhou University has passed the pilot test. Once the technology is mature, it can be popularized throughout the country. 
 not only is the technology of wool removal and hair removal, no ammonia deashing, sulfur free and low sludge leather making technology, chromium rich sludge deep processing and preparation of powdered chrome tanning agent are also widely used in Haining leather making enterprises. 
 "Haining is in the leading position in the application of advanced technology in leather making," Lan Yunjun said. There is still much room for future research and development of tannery environmental technology. In some specific projects, it already has a good vision and development platform.
