Business Club August 24th, due to sewage "double control", many printing and dyeing companies have been limited production and increased pressure. However, the Xinyu Printing and Dyeing Plant in Shaoxing Town, Shaoxing City, Zhejiang Province, is still producing at full capacity. "Because of the earlier introduction of biochemical treatment technology into technological transformation earlier last year, the sewage concentration was lowered in advance. Therefore, the introduction of a new discharge policy has no impact on us," said the person in charge of the company.
Luan Town is a “Chinese knit townâ€. Printing and dyeing companies mainly use polyester fabrics and other knitted fabrics. It is understood that among the 12 large-scale printing and dyeing enterprises in the town, 8 printing and dyeing companies have already started the process of biochemical dyeing and printing. Compared with traditional techniques, the printing and dyeing companies that launched these biochemical processes have significantly reduced the amount of sewage discharged and the sewage concentration has been significantly reduced.
According to reports, in May last year, Xinyu Printing and Dyeing Plant invested nearly RMB 5 million on the basis of the original physical and chemical treatment, adopted biochemical technology, and built a wastewater treatment tank covering an area of ​​about 1,300 square meters, with a daily sewage capacity of up to 5000 tons was officially put into use in June this year. With the same production capacity and product quality, in June of this year, the COD concentration in the printing and dyeing wastewater of the company was controlled at 400mg/l, which was more than doubled from the previous month. "There is also a potential for decline. In July, the COD concentration has dropped to 380 mg/l," the company official said. Because of this, the production of Xinyu Printing and Dyeing Plant was completely unaffected when Shaoxing City raised the industrial wastewater discharge to the COD concentration of 500mg/l.
Biochemical treatment process was adopted to achieve energy conservation and emission reduction. The Dawan dyeing and weaving company in Luan Township also tasted the sweetness of early emission reduction actions. “Big Bay Dyeing and Weaving†Bengbu Town was the first company to adopt “jet aeration biochemical process and equipmentâ€. As early as the end of 2009, the daily treatment of 5,000 tons of sewage biochemical treatment project had been solved by “Dawan Dyeing and Weavingâ€. Drainage trapped. “The COD concentration in the company's sewage has been controlled at 300mg/l since its operation for two years, which puts the company's focus even more on product quality improvement. It is reported that since the beginning of this year, this company has not only had a weak business in the summer and light season, but also printed. Dyeing processing fees have also successfully achieved price increases.
