摘　　要：采用试验与评价相结合的方法,以城市污水为原水,进行沉淀、混凝沉淀、DE氧化沟系统、移动床生物膜反应器（MBBR）4种工艺试验,并根据试验结果对城市污水的可处理性进行量化评价,为污水处理工艺的合理选择提供可靠的参考.工艺试验和评价结果表明：沉淀1 h能去除49.5%的悬浮态污染物,混凝沉淀对悬浮态污染物去除率可达98%,且处理效率为其他工艺的3.5-32倍;MBBR对溶解态有机物去除率与DE氧化沟相近,处理效率为后者的3-3.4倍;DE氧化沟对各类污染物去除率均在80%以上,但效率较低.Treatment effect and efficiency of sedimentation,coagulation-sedimentation,oxygen ditch and moving bed biofilm reactor（MBBR） which could be given by methods of combination experimental and evaluation,and domestic wastewater was used as raw water in the experiment.The treatment effect and efficiency were used to evaluate quantitatively the treatability of domestic wastewater and which could provide reliable reference for wastewater treatment progress selection.The experiment results indicated that sedimentation 1h could remove 49.5% of SS,coagulation-sedimentation could remove 98% suspended and the efficiency was 3.5-32 times more than other progresses,treatment effect of coagulation-sedimentation were also decided by quantity of suspended and colloidal in wastewater.MBBR could effectively remove dissolved organic matter and the efficiency was 3-3.4 times more than that of DE oxygen ditch treatment system which could remove more than 80% contaminates of wastewater,but less efficient.
