Abstract

The invention relates to a high-powered recycling process of coal-chemical industry clean wastewater and a special device for the high-powered recycling process. The coal-chemical industry clean wastewater is subjected to multistage clarification, ultrafiltration and osmosis treatment, the water recovery rate of the clean wastewater ultimately reaches above 95%, the purpose of high-powered recycling of the coal-chemical industry clean wastewater is achieved, the water resource is saved and the difficult problem of the deficiency of the fresh water resource is solved.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry waste water treatment and environmental protection, and specifically relates to a high-power reuse process for clean waste water in the coal chemical industry and a special device thereof. Background technique [0002] The modern coal chemical industry is a new type of industry that takes coal as raw material, converts coal into gas, liquid and solid products through chemical processing, and further processes it into a series of chemical products. It mainly includes coal gasification, coal liquefaction, tar chemistry, and calcium carbide acetylene chemistry. In recent years, the coal chemical industry has developed rapidly, but because the coal chemical industry needs to consume a lot of water, the resulting water resource reuse and environmental Protection issues are becoming more and more prominent, especially in areas with a lot of drought and little rain. Therefore, the environ...
