On the afternoon of July 24th, a special technical service of advanced treatment of printing and dyeing wastewater organized by the expert service group of Zhejiang provincial environmental protection department was held at the Party School of Keqiao District Committee of Shaoxing City, Zhejiang province. The heads of more than 80 dyeing and printing enterprises and relevant technical leaders came to the experts to seek the "best way" for sewage treatment to meet the standards.

stay scene The enterprise is responsible for the face clearly showing the desire to meet the target of wastewater treatment. "I heard that today is a meeting on wastewater treatment, so I dropped my business and came to attend." Cao Jiangang, deputy general manager of Lanting Pavilion Eagle printing and dyeing Co., Ltd., was quite positive at the scene. "For our enterprises, what we most desire is to help enterprises solve the problem of reaching the standard of wastewater." Cao Jiangang's words aroused the sympathy of the people in charge at the present company, and we all stated that the treatment of waste water is the primary task of the printing and dyeing enterprises.

Come from Zhejiang Province Wang Hongxiao, head of environmental public science and technology innovation service platform management, has been concerned about the wastewater treatment technology of dyeing and printing enterprises in Keqiao district.

It should be said that in the implementation of a round of environmental protection standards, Keqiao printing and dyeing enterprise wastewater treatment technology dares to taste, but also willing to spend money. However, in the face of the expectations of printing and dyeing enterprises, Wang Hongxiao pointed out that for printing and dyeing enterprises, the treatment of waste water is a systematic project. Three of them depend on technology and seven on management.

Wang Hongxiao's view has won the recognition of many participants. A printing and dyeing enterprise from the Keqiao Development Zone introduced a professional environmental protection company responsible for the operation of waste water in April this year, and paid it to the environmental protection company at the price of 3 yuan per ton. According to the annual wastewater treatment volume of 3 million 500 thousand tons, it is estimated that the annual waste water expenditure will be 10 million 500 thousand yuan.

"It is worthwhile for a professional company to manage waste water treatment," said Shen, deputy general manager of the company. The same wastewater treatment system, the same product mix, the COD concentration of the effluent from April dropped by 100mg/L a month.

"Printing and dyeing enterprises in Keqiao have a lot of money to deal with waste water treatment technology, but the management of waste water treatment is not enough." Wang Qiang, director of the waste water treatment department of Qixian town printing enterprise, said that their company invested tens of millions of yuan in the treatment of wastewater by reverse osmosis membrane technology. Although the company has already set up more than 20 people's wastewater treatment department, only three or four people know well in technology and management.

"From Implementation Since the waste water treatment and management for more than half a year, it has always felt that the pressure of wastewater treatment is very heavy, and there are not many breakthroughs. Wang Qiang sighed.
