摘　　要：采用低温等离子体协同Fenton氧化法处理聚丙烯酰胺(PAM)废水,研究了废水p H值、放电时间、放电电压、H_2O_2/Fe^(2+)比对PAM废水COD降解率的影响。结果表明,影响PAM废水COD降解率因素主次为:废水p H值>放电时间>放电电压>H_2O_2/Fe^(2+),当PAM废水p H值4,放电时间60 min,放电电压8 k V,H_2O_2与Fe^(2+)比值为9∶1时,废水净化效果最好,PAM废水COD降解率为76.32%。Non-thermal plasma combined with Fenton reagent has been applied to treat PAM wastewater.The effect of wastewater initial pH value,discharge time,discharge voltage and the ratio of H2O2 to Fe^2+on COD degradation rate from PAM wastewater was investigated.The result showed that the factors affecting the COD degradation rate of PAM wastewater were determined as follows:wastewater initial pH value>discharge time>discharge voltage>H2O2/Fe^2+,the COD highest removal rate of PAM wastewater reached 76.32%,when the optimum conditions are as follows:pH is 4,discharge voltage is 8 kV,discharge time is 60 min,the ratio of H2O2 to Fe^2+is 9∶1.The research provides a basic theory and technology for PAM wastewater treatment.
