| 摘 要： | 采用厌氧塘/预曝气/絮凝沉淀/好氧生化工艺对工业废水所占比例较高的城市污水进行中试研究.结果表明,厌氧塘出水经30 min的预曝气后进行絮凝沉淀,当FeSO4投加量为150mg/L、聚合氯化铝(PAC)投加量为100 mg/L时,对COD的单元去除率能够达到52%,且BOD5/COD值由0.4提高到0.6;对好氧系统采用周期性改变反应池内溶解氧浓度和外加碳源的措施,能够提高生物脱氮效果;经该工艺处理后,出水水质能够达到GB 18918-2002标准的一级B标准;经核算,该工艺的直接运行成本为0.65元/m3(不合污泥处理费).

| Abstract: | The anaerobic pond/preaeration/flocculation and sedimentation/aerobic biological process was used to treat the municipal wastewater with high proportion of industrial wastewater.When the flocculation and sedimentation of the effluent from the anaerobic pond after the preaeration of 30 min is performed by adding FeSO4 of 150 mg/L and PAC of 100 mg/L,the removal rate of COD is 52%,and the value of BOD5/COD is increased from 0.4 to 0.6.The periodic adjustment of DO in the aerobic system and the addition of car... |
