The Progress of the Application of Several Advanced Oxidation Processes on Pesticides Wastewater Treatment

摘要: 综述了光催化氧化(photocatalytic oxidation)、臭氧氧化(ozonation,O3)、芬顿试剂氧化(fenton reagent oxidation)等高级氧化技术以及它们的组合技术在农药废水处理中的应用研究进展,比较分析了各种高级氧化技术的特点与处理效果。就处理效果而言,通常情况下,UV(ultraviolet)/Fenton法＞UV/H2O2/Fe3+＞UV/H2O2＞UV/O3＞Fenton、O3、UV法,其中UV/Fenton法对农药等难降解的有机污染物的降解具有较大的潜力。同时介绍了几种高级氧化技术的经济成本分析方法,分析了目前高级氧化技术应用研究中存在的不足及今后研究中需进一步关注的问题。

Abstract: The application of photocatalytic oxidation,ozonation,Fenton reagent oxidation and the combination of these advanced oxidation processes in the treatment of pesticides wastewater were reviewed.The characteristic and efficiency of different processes were analyzed to compare with these technologies.As far as the degradation efficiency,UV/Fenton＞UV/H2O2/Fe3+＞UV/H2O2＞UV/O3＞Fenton,O3,UV,so UV/Fenton may be the most attractive treatment process.Besides,the method of cost analysis was introduced.The deficiencies existing and the future research direction in application and research of advanced oxidation processes were discussed.
