摘要
采用Fenton试剂氧化降解含油废水中的聚丙烯酰胺,研究了H2O2用量、催化剂种类及用量对降解聚丙烯酰胺效果的影响。结果表明,H2O2用量为聚丙烯酰胺的20%为宜;CuCl2具有和FeSO4、Fe(NO3)3、FeCl3相近的催化效果,并且可以作为一种在较高pH值条件下应用的催化剂;在优选条件下该氧化体系可以使聚丙烯酰胺黏度大大降低。
Using Fenton reagents to degrade polyacrylamide in the oily wastewater,we studied the impact of H2O2 dosage,catalyst types and dosage on the degradation effect of polyacrylamide.The experimental results showed:the optimum amount of H2O2 was 20% of polyacrylamide;CuCl2 had the similar catalytic effect as FeSO4,Fe(NO3)3 and FeCl3,and might be used as a catalyst in higher pH values;under the optimum conditions,the viscosity of polyacrylamide was decreased greatly.
