摘　　要：采用O3/KMnO4化学氧化法与曝气生物滤池(BAF)联用工艺处理生活污水二级出水,进行长期连续实验,考察pH、O3/KMnO4投加顺序和投加量对氧化效果的影响。结果表明:采用O3/KMnO4化学氧化法在pH为7.2～7.6的条件下,当O3和KMnO4投加量分别为10和1.5 mg/L时,ρ(BOD)/ρ(COD)由0.13提升至0.26,COD和UV254的去除率分别为30.90%和31.97%。在此基础上采用O3/KMnO4/BAF联用工艺,COD和UV254去除率分别提高至71.30%和74.86%。A long-term continuous experiment was carried out to treat sewage secondary effluent using ozone-KMnO4-biological aerated filter （BAF）. The effects of pH, addition dosage and addition sequence of O3 and KMnO4 on the oxidation effeciency were investigated. The results showed that BOD5/COD was improved from 0. 13 to 0. 26, and removal rates of COD and UV254 were 30.90% and 31.97% , respectively, under the conditions of pH of 7.2 - 7.6, ozone dosage of 10 mg/L and KMnO4 dosage of 1.5 mg/L, respectively. And furthermore, removal rates of COD and UV254 were enhanced to 71.30% and 74.86% , respectively, by using O3-KMnO4-BAF.
