摘要
我国是一个多煤少油的国家,因此煤炭的利用率、污染治理对于我国十分重要,煤化工废水具有污水排放量大、污染物种类多、污染物浓度高的特点,处理极为困难,极大地限制了我国煤化工产业的发展,本文阐述了煤化工废水的来源、特点以及组分,煤化工废水的预处理、二级处理、深度处理的全过程,预处理有气浮、隔油、脱氮、脱酚;二级处理工艺A2O、SBR;深度处理混凝、吸附、高级氧化等方法,最后则是对煤化工废水处理的展望。
China is a country with more coal and less oil. Therefore, the utilization rate of coal and pollution control are very important to our country. Coal chemical wastewater has the characteristics of large sewage discharge, many types of pollutants, and high concentration of pollutants, so it is extremely difficult to treat and restrict the development of China’s coal chemical industry. This article explains the source, characteristics and components of coal chemical wastewater, the whole process of pretreatment, secondary treatment and advanced treatment of coal chemical wastewater. The pretreatment includes air flotation, isolation, denitrification and dephenol;secondary treatment process A2O, SBR;advanced treatment methods such as coagulation, adsorption, advanced oxidation, and finally the coal chemical wastewater treatment is prospected.
