摘　　要：城镇污水处理厂是指对进入城镇污水收集系统的污水进行净化处理的污水处理厂,此次研究以呼和浩特市区日处理量20万m3城镇污水的辛辛板污水处理厂为对象,对其各级处理阶段的主要污染因子进行采样检测,分析主要污染因子在各处理阶段的变化情况,并对各级处理阶段的处理效率和主要污染因子的削减率进行研究,发现其二级处理阶段对各主要污染因子均有较强的处理效果,五日生化需氧量、氨氮、总氮、总磷和阴离子表面活性剂的绝对削减率最高值出现在该阶段;而化学需氧量、悬浮物、动植物油和石油类的绝对削减率最高值出现在一级处理阶段。Urban sewage treatment plant refers to the sewage into the urban sewage collection system for purification treatment of sewage treatment sewage treatment,this study to Hohhot urban daily treatment of 200,000 m3 urban sewage treatment plant,the main pollution factors at all levels of the treatment stage sampling and testing,Analysis of the main pollution factors in the various stages of treatment,and the treatment efficiency of the treatment at all levels and the reduction rate of the main pollution factors,found that its secondary treatment stage has a strong treatment effect on the main pollution factors,the highest absolute reduction rates of BOD5,NH3-N,TN,TP and LAS occurred at this stage.However,the highest absolute reduction rates of CODcr,SS,animal and plant oil and petroleum appear in the primary treatment stage.
