Zhejiang Textile Mill Hit 25 Million "Biochemical" Sewage Treatment

< p > in March of this year, the sewage treatment and reclaimed water reuse project of Zhejiang leather textile Co., Ltd. was accepted by experts from the provincial science and technology department and the provincial Environmental Protection Industry Association.

"Since the project has run, all indicators are in line with the standard of admission."

Shen Mingrong, general manager of the company, was satisfied with this.

< p > project site, real-time data monitoring room on the big screen beating a set of data: the effluent COD content is 54mg/L, and the water content is 10mg/L, much lower than the "textile dyeing and finishing industry water pollutant discharge standard" 200mg/L, and ordinary river water is not different.

Before treatment, the COD content of sewage was 800mg/L.

< p > the key to such a remarkable processing effect lies in the application of biochemical technology.

The bacteria in the treatment pond can efficiently degrade pollutants in the water.

At the same time, the amount of sludge generated is only 1/10 of the original.

It is understood that this project is the first project in the province to directly rely on biochemical technology to directly treat dyeing and finishing sewage to achieve the discharge standard of pollutants in textile dyeing and finishing industry.

After biochemical degradation, sewage will also be purified by new resin material, which is the core link of reclaimed water reuse.

After treatment of sewage, and then through the adsorption of resin materials, you can get cleaner water, recycling for enterprise production.

< p > < < a href= > http:// > www.91se91.com/news/index_c.asp > printing and dyeing industry < /a > sewage treatment has always been a problem to overcome in the whole province's water environment protection.

Huang Yinan, an expert at the provincial Environmental Protection Industry Association who participated in the project's on-site assessment, told reporters that the resin recycling technology used in PI Yi textile was also the first in the province, and it has a certain promotional significance in the "five water co governance" work.

< p > < strong > heavy investment, annual savings of more than 160 million /strong < /p >

< p > < a href= "http://? www.91se91.com/news/index_c.asp" > pi Yi textile > /a > is a textile dyeing and printing enterprise. The general manager Shen Mingrong has always attached great importance to enterprise environmental protection. "This is not only the social responsibility of enterprises, but also the embodiment of competitiveness of enterprises."

In the 8 projects that are available for Shen Mingrong screening, the total investment of Pu Tai environmental protection is 25 million yuan, which is the most expensive in all projects, but Shen Mingrong thinks that the money is worth it.

< /p >

< p > since last year, we carried out the comprehensive reform of factor marketing allocation. Our city has implemented strict differentiation policy for printing and dyeing enterprises.

Although PI Yi textile is still in the construction cycle, it has not yet been included in the evaluation system, but the cost of business is rising and the pressure is also increasing.

A simple account, peyi textile last year's COD emission quota was 62.61 tons, the total emission trading price was about 250 thousand yuan, and the sewage discharge amounted to 317152 tons.

If the B class is included, not only the emission reduction task will increase, but also the emission trading price and water fee will be raised; and more importantly, after the implementation of multi factor compliance pricing, the annual sewage treatment cost will exceed 1 million yuan.

< /p >

< p > "early change is better than late change. Active change is better than passive change."

Shen Mingrong admitted that although the investment in sewage treatment facilities was very high, in the long run, the economic and social benefits were considerable.

It is estimated that through the project, the theory of leather textile can achieve 50% of the wastewater reuse. It can save 700 thousand tons per year, reduce COD140 tons, and save various expenses of 1 million 640 thousand yuan.
