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

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.
