试验考察了UV／Fenton法和CCG788／UV／Fenton法对浮选废水进行预氧化后，废水中COD去除效果的影响因素。其结果表明：UV／Fenton 法处理效果明显优于普通 Fenton 法，而CCG788的加入提高了 UV／Fenton 体系对紫外光的利用率，不仅氧化效果更好，还可以促进UV／Fenton氧化反应的进行，缩短反应时间。在前述试验结果基础上，对CCG788／UV／Fenton法处理后的浮选废水投加CCG158进行了二次氧化，COD去除率可提高到87％，并缩短了总反应时长。

Pre-oxidation of flotation wastewater by UV/Fenton and CCG 788/UV/Fenton process was exploredin terms of the influence factors on COD removal.The experiment results show that UV/Fenton oxidation process is much more effective for the pre-treatment of flotation wastewater than Fenton oxidation process.In addition,the introduction of CCG788 into UV/Fenton system improves the utilization of ultraviolet ray( UV) and removal rates of COD,as well as promotes oxidation reaction and shortens the reaction time.Furthermore,the total removal rate of COD can reach 87 %by secondary oxidation of CCG788/UV/Fenton flotation wastewater with CCG158,and the reaction time is shortened.
