Problems solved by technology
[0006] The purpose of the present invention is to provide a high-power recycling process and special equipment for coal chemical concentrated brine in order to solve the technical defects of low reuse utilization rate and easy blockage in the above-mentioned existing coal chemical concentrated brine advanced treatment process. The concentrated brine of the chemical industry is treated by two-stage clarification and softening, ultrafiltration, ion exchange softening, and two-stage reverse osmosis. The water recovery rate reaches 75%-85%, which is significantly improved compared with the existing concentrated brine recovery rate of 60%-70%. , so as to achieve the goal of high reuse of concentrated brine in coal chemical industry

Abstract
The invention discloses a high-power reuse technology for coal chemical industry strong brine and special equipment of the high-power reuse technology. The coal chemical industry strong brine processed by the method of carrying out two-stage clarifying and softening; carrying out ultra-filtration; and carrying out ion exchange softening and two-stage reverse osmosis. The recovery rate of water reaches 75%-85%; and compared with existing recovery rate of strong brine, the recovery rate is significantly improved by 60-70%, thus the high-power reuse target of the coal chemical industry strong brine is achieved.
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 coal chemical industry concentrated brine high-power reuse process and special equipment. 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 environmental protection...
