摘要
针对离子交换树脂再生废水中的难降解有机物利用Fenton试剂进行催化氧化处理。实验结果表明:当反应条件是H2O2与FeSO4·7H2O摩尔比为5∶1、H2O2(30%)投加量为0.35mol/L(4次投加)、pH值为3.5、反应时间为2h时,废水的处理效果最佳;并采用正交实验确定了各反应因素对废水的CODcr去除效果的影响水平。
Catalyzed oxidation of regenerating wastewater of ion -exchange resin with Fenton reagent was studied in this paper. The experiments showed that the effects are the best when the mole ratio between H2O2 and FeSO4 ·7H2O is 5 ： 1, H2O2 （30%） is 0. 35 mol/L, the pH is 3.5 and the reaction time is 2 hours. And we got to know how the various reaction factors affect the results of the removing of the CODcr in the wastewater through the orthogonal test.
