Because of pollution "double control", many printing and dyeing enterprise production is restricted, pressure increase. But located in shaoxing, zhejiang province town of zhu Li XinYu dye factory is still full production. "Thanks to earlier last year in the technical improvement by biochemical process, reduce the sewage concentration in advance, so new sewage policies, has no effect on to us." This enterprise officials said.

Li zhu town is the "China knitting name town", printing and dyeing enterprise to polyester fabric knitted printing and dyeing primarily. According to understand, the whole town 12 scale above printing and dyeing enterprises, already 8 home printing and dyeing enterprise mount the printing and dyeing biochemical process. Compared with the traditional process, the Li taozhu horse bio-chemical technology of printing and dyeing the enterprise, obviously reduced amount, sewage concentration significantly.

According to understand, last may, XinYu dye factory in the original physico-chemical treatment on the basis of, and investment of nearly 5 million yuan, used the biochemical technology, the construction of more than 1300 square meters of sewage ChuLiChi, in every day carrying capacity of 5000 tons, June this year has been put into use. In the production and the product quality under a constant, in June this year, this enterprise printing and dyeing wastewater COD in concentration control in 400 mg/l, up more than double last month to reduce. "The potential is lower, and in July COD concentration has fallen to 380 mg/l." This enterprise relevant researchers said. Also because of this, in shaoxing city industrial waste water discharge will DiBiao to COD nanotubes concentration 500 mg/l, XinYu dye factory production completely was not affected.

The biochemical process, and realize the energy conservation and emission reduction, Li taozhu town bay textile company is more a taste of the early early action emissions reduction reaping the rewards. "Bay of dyeing" Li zhu town is the first one USES "jet aeration biochemical process and equipment" of the enterprise, as early as the end of 2009, 5000 tons of wastewater treatment, biochemical treatment project is already for "big bay of dyeing" pollution of the trapped. "Operation two years since, company COD in sewage concentration control in 300 mg/l, this let enterprise focus more on product quality to carry on. It is reported, the shift since this year, the company not only summer season business not light, light and printing dyeing processing also successfully realized the prices.
