【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。
[Abstract]:The oxidative degradation of HPAM by Fenton-like reagents was studied by peracetic acid oxidation and starch-cadmium iodide method in the treatment of simulated partially hydrolyzed polyacrylamide (HPAM) wastewater. The effects of oxidation time, initial concentration and pH value on the degradation of HPAM were investigated. The optimum operating conditions were determined as follows: [CH_3COOOH] = 10 mg 路L, [Fe~ (2)] = 400 mg / L, pH 鈮，
