摘　　要：焦化废水氨氮含量高,成分复杂,直接处理可能会对生物反应器造成影响。使用吹脱方法对焦化废水进行预处理,在pH值为10时可使氨氮降至120 mg/L,之后使用好氧的方法处理吹脱除氨后的焦化废水,经过驯化后焦化废水的出水COD可降至300 mg/L,加入葡萄糖进行共降解可以缩短好氧反应器启动时间。The coking wastewater has high ammonia nitrogen content and is complex in composition, which may affect bioreactors. Pretreatment of coking wastewater with ammonia-nitrogen desorption method, the ammonia nitrogen could be reduced to 120 mg/L at a pH value of 10. After the aerobic treatment of coking wastewater, the effluent COD of coking wastewater after acclimation can be reduced to 300 mg/L. Adding glucose for co-degradation can shorten the aerobic start time.
