Shaoxing County Turned Itself Into A "Green Dye Vat".

< p > < < a href= > http://www.91se91.com/news/ > printing and dyeing enterprise > /a > burden reduction. Shaoxing county set up green printing and dyeing base in Binhai Industrial Area. It will be dispersed in 96 printing and dyeing enterprises across the county and gradually gathered to < a href= > http://www.91se91.com > printing and dyeing base < /a >.

This not only solves the problem of sewage treatment of enterprises, but also greatly improves the printing and dyeing industry's production efficiency.

< /p >

< p > as one of the traditional pillar industries, Shaoxing county has a href= "http://www.91se91.com/news/index_c.asp" > printing and dyeing > /a > nearly 200 enterprises. In the past, "Stocking" sewage sludge treatment method has brought greater pressure to local environmental protection and energy saving and emission reduction work.

Take Shaoxing Huaxia dyeing and printing company as an example, the company produces about 4000 tons of printing and dyeing wastewater.

In the past, these production sewage enterprises need to pre process themselves.

"To invest in professional sewage treatment equipment, we need specialized technical personnel, only sewage treatment tanks and other land areas will be several mu."

According to Xu Chun Chang, a Chinese dyeing and printing company, it is not only time-consuming and laborious but also has some hidden dangers to solve the problem of sewage in factories.

In the past few days, with the other 22 printing and dyeing enterprises, Hua Xia printing and dyeing company as the first batch of enterprises, P is moving the factory into the coastal green printing and dyeing base.

At this base, the new Shaoxing County riverside water treatment Co., Ltd. has become the public sewage pool of these printing and dyeing enterprises.

"Now centralized treatment, sewage directly through the pipeline into the steady flow tank of the riverside company, the direct cost of our enterprises has been reduced by 30%."

Xu director Chang said.

< p >, as an important supporting project of littoral < a href= "http://www.91se91.com" > green printing and dyeing < /a >, Shaoxing riverside water treatment Co., Ltd. is not only a simple sewage treatment plant.

"The advanced bioreactor technology of sludge bioreactor has been adopted. After comprehensive treatment, the effluent can be recycled to achieve the reduction and utilization of water resources."

According to Wang Xingliang, chairman of Jiang Bin water treatment Co., Ltd., its sewage treatment projects include three major projects, including pretreatment, land disposal and advanced treatment of sewage. After centralized treatment of these sewage, Shaoxing county can reduce COD (chemical oxygen demand) total 108 thousand tons a year.

< p > in the printing and dyeing industry, sludge is a by-product of industry. It is also a long-standing problem faced by enterprises. At present, the general way of disposal is landfill, but this will not only create new pollution, but also occupy a lot of land resources.

The Binhai green printing and dyeing base has also paid a lot of attention to sludge disposal. The investment of 500 million yuan for the sludge incineration power generation heating project is under construction.

After the completion of the project, the sludge generated by the riverside company in the sewage treatment process will be sent to the sludge incinerator through the network, and the sludge will generate electricity through incineration and heating.
