24 Water And Leather Enterprises To Achieve Sewage Discharge

"Lishui Economic Development Zone will win the first battle of industrial pollution control in an all-round way." In October 30th, with the newly released test report, Liu Changlin, director of the Environmental Protection Bureau of the Development Zone, said excitedly, "after testing, all 24 synthetic leather enterprises have achieved the discharge of sewage."

"This means that sewage The destruction of ecology has been eradicated for many years. The pollution of synthetic leather industry can be controlled and cured. Lishui Economic Development Zone (gathering area) party work committee secretary Chen Jingfei said.

In accordance with the provincial and municipal regulation tasks and requirements, the development zone has set up "five time points" for synthetic leather enterprises in the next two years. Among them, "before the end of September, enterprises must pass the sewage treatment and acceptance", otherwise they will "shut down and rectify".

To this end, at 0:00 a.m. on October 1st, the development zone was on time for all enterprises' physical examination. According to the standard, the pH value of wastewater discharged by enterprises should be controlled within 6-9, COD should not exceed 500mg/L, and ammonia nitrogen content should not be higher than 35mg/L.

The results showed that the average value of three major testing indexes of 24 synthetic leather enterprises were: pH 7.6, chemical oxygen demand 95.8mg/L and ammonia nitrogen content 4.4mg/L. among The content of chemical oxygen demand and ammonia nitrogen is much lower than the testing standard.

Knowing the news, Xu Zhen, director of the provincial environmental protection department, said for the first time: "good! It's hard to be good." Congratulations! Liu Changlin said: "cutting off the source of water pollution is crucial to improving the hardware and containment of new sources of pollution in the Development Zone, and further boosting the confidence of the whole area."

Zhejiang Minfeng Chemical Co., Ltd. is the first company to accept the test. The sampling results showed that the pH value of the wastewater was 7.55, the chemical oxygen demand was 21mg/L, and the ammonia nitrogen content was 0.656mg/L.

"Invest 7 million 800 thousand yuan, add sewage treatment equipment, daily water quality monitoring, establish a system, meticulous. Attitude is the key to "flood control." Shao Ye, chairman of the company, said: "we have never paid much attention to pollution control, and have never invested so much manpower, material and financial resources to deal with pollution. of therefore In this way, only by strictly controlling pollution can enterprises have room for development.

In addition to Minfeng company, Zhejiang Xin Xu synthetic leather Co., Ltd. also made the same score in this big test: pH 6.51, chemical oxygen demand 36mg/L, ammonia nitrogen content 9.46mg/L.

"Sewage treatment is very difficult, waiting for detection is very painful, see the result is very gratifying." Li Xindi, chairman of the board, said that the decision of the development zone for water control enabled him to re-examine the concept of enterprises, and that it was precisely the environmental protection that forced the enterprises to stride toward Transformation and upgrading. Now, the new product development and new technology application of Xin Xu company has obviously accelerated, and the competitiveness of enterprises has been greatly improved.

Behind the beautiful transcripts, now the Development Zone synthetic leather enterprises spontaneously set up pollution control detachment, strict self supervision to become a new enterprise management system, the entire development zone has also become the national demonstration base to build eco synthetic leather. Chen Jingfei said: "next, the development zone will fully exhaust the waste gas treatment, complete the ecological transformation of the synthetic leather industry, and completely remove the" pollution cap "for Lishui.
