Dongguan, Guangdong: 50% Of The Tanning Industry Can Be Reused After Waste Water Treatment.

Reporters yesterday (June 17th) learned that the Dongguan Environmental Protection Bureau requires these enterprises to complete the rectification before the end of September, so as to reduce COD.

The content of rectification and improvement is that further treatment measures should be taken on the basis of the current discharge standards, so as to improve the removal rate and make the wastewater 50% used for production after effective treatment.

The responsible person said that the wastewater discharged by these enterprises was discharged after reaching the standard after treatment and did not require reuse.

The reason for choosing these 30 enterprises as environmental protection enterprises is to raise the scope of rectification and improvement, because these enterprises are all jeans washing and washing enterprises, and the water demand is large.

Among the six industries, such as electroplating, bleaching and dyeing, paper making, tanning, washing and printing, there are 1252 key polluting enterprises. The total annual wastewater discharge is 1.8 million tons, accounting for 78% of the total annual industrial wastewater discharge.

The waste water has caused serious pollution to the Shima River, Dongyin canal, Cold Creek River and South she Lang, and threatened the water quality of Dongjiang drinking water source and major reserve water sources.

The Environmental Protection Bureau official told reporters that there are more than 500 washing enterprises in the city, including jeans washing water and wool washing enterprises.

In the 32 towns (streets) of Dongguan, the most polluting enterprises are Changping towns, of which 209 are total, of which 187 are washing enterprises.
