Longyu Coal Chemical Water Reuse Project Investment

At the entrance of the water purification station of Henan Longhua Coal Chemical Industry Co., Ltd., Henan Water Treatment Co., Ltd. saw that the treated water flowed out like a clear spring. The company's water recycling project was put into use in early June. It can handle 15,000 cubic meters of municipal wastewater and industrial wastewater every day, and can meet 60% of the company's water consumption, generating at least 10 million yuan of economic benefits each year.

It is understood that with the increasing production load, the consumption of water resources by Longyu Coal Chemical Company has also increased. The original water system is increasingly unable to meet the needs, and the “water shortage” symptoms of the device gradually become red. light. Faced with the predicament, the company's technical staff will look to the city sewage and industrial wastewater.

The reason for this consideration was that the company had invested RMB 250 million in 2007 to build two sewage treatment plants. "However, the water from the sewage treatment plant is what we often call 'water', and the water quality of the water must be treated in depth before it can be used effectively as a production circulating water, otherwise the pipeline will be contaminated due to the production of algae bacteria." The company’s chief engineer Li Shengjun said. The company immediately decided to list the reclaimed water reuse project as a major scientific and technological special project. After five program demonstrations, the company launched the Zhongshui reuse program relying on raw water pretreatment equipment.

“Because the plan was optimized based on actual conditions, basically no additional equipment was added. It was only necessary to lay pipes to connect the WWTP to the water purification station built by our company in May this year. Therefore, the project was implemented quickly and completed in less than two months. Li Shengjun said, "In this way, it not only solved the problem of insufficient water supply, but also improved water quality."
