Get Through The Road Of Textile Industry Recycling

"After treatment, the sewage can reach the two grade standard of groundwater in China, which is even higher than that of three kinds of water that is suitable for drinking."

Before standing on the clean white ultrafiltration and reverse osmosis equipment, Wang Jidai said that after pretreatment, aeration and other links, the water quality can reach the first level A discharge standard of municipal sewage, and then enter the ultrafiltration and reverse osmosis equipment.

"The filter membrane in the equipment is very tight, and the water molecules are relatively small, which can permeate through the filter membrane. The molecules of bacteria and metal ions are much larger and can not be squeezed, so the treated water is like pure water."

He said.

Gaoyang is a large textile County in our province. A large number of printing and dyeing wastewater has been a "bottleneck" for the development of textile industry in this county.

"Sewage can not be treated, enterprises must shut down and stop production."

Liu Lipeng, deputy governor of Gaoyang County, said that with the enhancement of environmental protection constraints, the county should grasp the pformation and upgrading of industries, and adopt a government led and enterprise operation mode to build sewage treatment plants.

Now, from

Hongrun new fabric Co., Ltd. invested and operated the sewage treatment plant. The daily capacity of sewage treatment reached 200 thousand tons, becoming the largest county level sewage treatment plant in the province.

After the full acceptance of industrial sewage and municipal sewage in the county, the actual daily processing capacity of the plant was 180 thousand tons, of which 30 thousand tons were recycled by 5 textile enterprises such as Hongrun company after ultrafiltration and reverse osmosis advanced treatment, and the remaining 150 thousand tons were discharged directly from the first class A emission standards.

"Printing and dyeing water requires very high water quality. Tap water contains calcium and magnesium ions, which must be removed.

The reclaimed water is very pure and can be directly used for production, and the price is 3 yuan per ton, which is cheap and comprehensive.

Wang Jidai said that with the increase in demand, more sewage will be further processed for recycling.

Here, the stability reaches the first level A.

The water quality of 150 thousand tons of water is better than that of agricultural irrigation, so it is fully utilized by farmers nearby.

In the autumn of September, reporters found that there were large quantities of rice in the sewage treatment plant. The green rice fields were green with the wind, and the heavy Rice Panicles were coming down to the earth.

One seat

The factory has opened up the circular economy of the textile industry in Gaoyang County, and now the circulating chain of the sewage treatment plant is extending to a wider field.

The project of large scale central heating boiler investing more than 400 million yuan is stepping up construction. After the heating season is put into operation next year, the residents of the county industrial area and the county seat will realize central heating. The existing 300 small coal-fired boilers will be demolished.

"The sulfur dioxide and soot emission concentration of the project is close to the standard of gas fired boiler."

Wang Jidai said that the waste heat in the sewage treatment will be replaced for heating, which can save 1/3 of the coal.
