摘　　要：采用生物接触氧化法处理含聚丙烯酰胺(HPAM)的模拟污水,考察了温度、聚丙烯酰胺浓度和污水中碳源含量对模拟污水COD去除和HPAM降解的影响。结果表明,在稳定运行阶段,温度为37℃和45℃时,COD平均去除率分别为60.1%、56.5%,HPAM平均降解率达63.3%、57.0%;聚丙烯酰胺浓度为100 mg.L-1和120 mg.L-1时,COD平均去除率分别为56.8%、51.5%,HPAM平均降解率为59.7%、55.5%,能满足国家污水二级排放标准的要求。Treatment of polyacrylamide wastewater was studied by biological contact oxidation. The influences of temperature, concentration of polyacrylamide, carbon source content on degradation rate of COD and HPAM were investigated. The results showed that the average degradation rate of COD was 60.1% and 56.5%, the average degradation rate of HPAM was 63.3% and 57.0% respectively when the temperature was 37℃ and 45℃, and the average degradation rate of COD was 56.8% and 51.5%, the average degradation rate of HPAM was 59.7% and 55.5% when the concentration of HPAM was 100 mg·L^-1 and 120 mg·L^-1 , respectively.
