| 摘 要： | 采用A/O工艺处理低碳源城市污水,研究了生物除磷和好氧反硝化脱氮效果及其影响因素。试验结果表明:①磷的出水浓度低于0.8mg/L,去除率达到92%~98%;②影响好氧反硝化的主要因素为DO和HRT。当DO控制在2mg/L左右,HRT控制在6h时,好氧反硝化效果最好。增加了脱氮效率,减少了碳源和需氧量。NH4+-N去除率高达94%,总脱氮率可高达76%左右。

| Abstract: | Effect and the factors influencing biological phosphorus removal and aerobic denitrification were studied using A/O process treat municipal wastewater with low carbon source.The results showed that:① Effluent target of Phosphorus is under 0.8mg/L,the removal rate can reach 92%～98%;②DO and HRT are the key factors influencing aerobic denitrification.The denitrification effect is the best when DO=2.0mg/L,HRT=6h,which the TN removal ratio is increased and the quantity of carbon source and oxygen demand is decreased.Finally,NH+4-N removal ratio can reach 94%,and TN removal ratio can reach about 76%. |
