In recent years, the leather industry has been renovating < a href= "http://zj.sjfzxm.com" > Haining < /a >, and there are only 8 left in 38 local leather enterprises, and the 8 enterprises have also upgraded the process equipment to minimize waste water entering the waste water.

< p > with the impression that tanneries are dirty and smelly, the situation of cross flow of sewage is different. The workshops in this plant replace manual labor with large machines, without sewage, and the smell is not obvious.

Xiao Zhiyu, executive deputy general manager of the company, told reporters that the cowhide of their factory came from Brazil. "The most serious pollution in leather making process is the processing from leather to leather in the initial processing, because this process will produce a lot of waste water.

What we are doing now is to finish the process in Brazil, and then return to China to reduce pollution from the source.

At present, the company's daily wastewater discharge is 800 tons, and if the initial processing is increased, the amount of waste water will be two times that of today.

< p > it is understood that in the treatment of sewage, the company also carried out the "three water separation" (that is, chromium containing wastewater, dyeing wastewater, comprehensive wastewater) pformation, reduced the pollution of heavy metals to water quality, carried out the overall pformation of the sewage station, stabilized the ammonia nitrogen emission index, and the ammonia nitrogen volume basically stabilized at 10mg/L.

At the same time, the production process is improved and the water consumption is about 20%.

"In the course of our investigation, we found that tannery wastewater in some countries can directly breed fish after treatment. We also plan to embark on a comprehensive utilization project of tannery wastewater to further reduce pollution."

Xiao Zhiyu said.
