摘　　要：以某小区污水二级处理出水为原水,采用高锰酸钾作为预氧化剂,在高锰酸钾最佳投药量4.5 mg/L,0.1 MPa和模拟管道的条件下模拟管道掺气氧化反应,测定不同掺气比时COD、氨氮、硝酸盐氮、亚硝酸盐氮和浊度各项指标数据,研究分析不同掺气比不同反应时间各项指标的去除效果,探索管道掺气氧化的效果,从而为实际污水处理工程提供一些参考。This paper uses the secondary treated wastewater from a residential area as the raw water,employing potassium permanganate as the pre-oxidant.Under the optimal dosing amount of potassium permanganate at 4.5mg/L,a 0.1MPa pressure and simulated pipe conditions,it simulated air mixing oxidation reactions in a pipeline.It measures the data of COD,ammonia nitrogen,nitrate nitrogen,nitrite nitrogen,and turbidity at different air-mixing ratios.The paper analyzes the removal effects of different air-mixing amounts and different reaction times on various indicators,aiming to explore the effects of pipeline aeration oxidation and to guide production.

关 键 词：污水处理 预氧化剂 掺气比
