Problems solved by technology

In order to reduce the environmental pollution caused by the waste water in the coal chemical industry, the existing coal chemical industry projects are carrying out "zero discharge" treatment of the waste water, but the existing zero discharge treatment process has various technical defects in the actual treatment process.
First of all, the recovery rate of wastewater is low, and the traditional coal chemical wastewater treatment cannot fully meet the discharge standards. The remaining 30% to 40% of the concentrated brine has not been reused, and it is directly treated as waste, resulting in a large amount of wastewater. It means that the system water recovery rate is low and the recovery rate i

Abstract

The invention discloses a coal chemical industry wastewater zero emission technology and special equipment thereof. Targets of coal chemical industry wastewater zero emission, high fresh water recycling and resource recycling are achieved due to the fact that the coal chemical industry wastewater is collected in a classified mode and processed according to quality to improve the water recycling rate and obtain industrial salt.

Description

technical field [0001] The invention belongs to the technical field of environmental protection treatment, and in particular relates to a coal chemical industry wastewater zero discharge process and special equipment thereof. Background technique [0002] With the continuous and rapid development of industry, industrial water consumption continues to increase. On the one hand, the severe situation of water resource shortage is exacerbated. On the other hand, the discharge of industrial wastewater will cause serious pollution to the environment. How to effectively improve the utilization of water resources has become an urgent problem to be solved. technical issues. The wastewater discharged from the industrial coal chemical industry is mainly high-concentration coal gas washing water and synthetic wastewater from chemical products, which contain a large amount of toxic and harmful substances such as phenol, oil, cyanide, ammonia nitrogen, etc., which can easily cause environ...
