Lurgi Leather Co., Ltd.

Section chief Li Guangdong said, the original production of a finished leather water consumption is 1.15 tons, now producing the same finished product only 0.3 tons of water, equivalent to 1/4 of the previous water consumption.

According to the calculation of one year's production of 250 thousand finished leather, the annual water saving amount to 210 thousand tons.

It is understood that the original Lurgi leather is chrome tanning process, the wastewater generated by simple atomization biochemical treatment has been discharged, the fresh water consumption per year is as high as 1 million tons.

In the face of strict energy consumption requirements, enterprises invest 12 million yuan to upgrade production lines and sewage treatment facilities. By adding two grades of biochemistry to reduce wastewater treatment targets, the workshop is reused.

Nowadays, the annual water consumption of enterprises is less than that of the previous quarter.

In Juye, more and more enterprises are investing more in environmental protection. The technology of reclaimed water is used to concentrate the waste water produced in the production process.

In addition to,

The conservation of sewage is also a key point.

The Qingyuan sewage treatment plant in Juye adopts the advanced treatment technology combined with biochemical and physicochemical treatment, turbidity removal and chemical oxidation disinfection process. After the water treatment process of the sewage treatment plant, the effluent quality reaches the national level a standard, and achieves the standard of industrial water and urban miscellaneous water use.

"Reclaimed water reuse" is a public welfare environmental protection project to control pollution and improve the environment. It has obvious environmental and social benefits. It can reduce pollution to surface water and improve the quality of urban surface water environment.

Qingyuan sewage treatment plant engineer Wang Xianhua said that at present, the sewage treatment plant daily treatment of sewage volume of about 30000 cubic meters, generating more than 8000 cubic meters of recycled water daily, of which more than 3000 cubic meters for bio power plants and giant run building materials and other enterprises to use, the remaining reclaimed water for wetland replenishment water and road spraying and greening use.

After pilot exploration, the water reuse project has been gradually extended to large water consumption households. At present, nine high water consumption enterprises, including coking, building materials, printing and dyeing industries and two sewage treatment plants have been taken into the recycling system, and nearly ten million tons of fresh water are saved in the year, and the economic benefit of about 20000000 yuan is created.
