论煤化工污水处理工艺选择

Discussion on the Selection of Sewage Treatment Process in Coal Chemical Industry

针对煤化工生产过程中产生的污水量大,且含有大量酚、氰、油、氨氮等有毒有害物质这一问题,对煤化工主要污水处理工艺进行分析研究,包括物化预处理、生化处理以及物化深度处理,以期为煤化工产业污水处理技术的选择提供借鉴。

The amount of sewage generated during the coal c h emical production process is large,and contains a large amount of toxic and hazardous substances such as phenol,cyanogen,oil,and ammonia nitrogen. This paper analyzes and studies the main sewage treatment process of coal chemical industry,including physical and chemical pretreatment,biochemical treatment and physical and chemical treatment,and also provides reference for the selection of coal chemical industry sewage treatment technology.
