摘　　要：采用缺氧-好氧-缺氧-好氧-生物膜工艺(AOAO加膜法),处理含多种有毒有害难生物降解有机物的化工综合污水。实验结果表明,该工艺可以部分或全部降解多种生物难降解有机物,污水COD降低38%,氨氮去除率也可以达到80%以上。The organic compounds in chemical industry waste water were treated by AOAO combined with biofilm process.The results showed that the organic compounds could be degraded partly or completely by AOAO combined with biofilm process.The removal rate of COD and NH_3-N in waste water reached more than 80%.

关 键 词：化工污水 生物降解 好氧 缺氧 硝化 反硝化
