摘要
以模拟部分解聚丙烯酰胺(HPAM)污水为处理对象,采用过氧乙酸氧化法和淀粉-碘化镉法,研究了类Fenton试剂对HPAM的氧化降解作用。考察了氧化时间、初始浓度、pH值等对HPAM降解性能的影响,确定了其最佳操作条件为:[CH_3COOOH]=10mg/L,[Fe^(2+)]=400mg/L,pH=3,反应时间为15min时,去除率可达81%。研究表明,CH_3COOOH为氧化剂的类Fenton氧化法对聚丙烯酰胺污水具有较好的处理效果。
The article focuses on simulation partially hydrolytic polyacrylamide（HPAM）wastewater and discusses the removal of HPAM through the peracetic acid oxidation and starch-cadmium iodide methods.The effects of oxidation time,initial concentration and pH on the degradation of HPAM were studied.The optimal conditions concerned were determined through experiments at room temperature：15min,[CH_3COOOH]=10mg/L,[Fe^（2＋）]=400mg/L,pH=3,the removal rate of up to81%.Generally,the a peracetic acid oxidation like-fenton oxidation method was proven as a high efficiency technique for treating wastewater with HPAM.
