摘要
焦化废水是一种成分极其复杂、污染物浓度高、毒性大、难处理的工业废水。某焦化厂对焦化废水采用预处理(蒸氨、脱氰)、生化处理(好氧-厌氧-好氧)和深度处理(砂滤-纳滤)净化后,出水水质可以稳定达到净循环水补充水水质要求,实现了"零"排放。
Coking wastewater is a type of refractory industrial wastewater with complex composi-tion, high concentrations of pollutants and high toxicity. Pretreatment （ammonia stripping and cyanide removal） , biochemical treatment （ aerobic/anaerobic/aerobic ） and advanced treatment （ sand filter/ nanofihration） were used in a coking factory. The effluent quality could meet the circulating water quality requirement and thereby realize the zero emission of coking wastewater.
