The Study On The Treatment Of Hard-degradation Organic Wastewater By Advanced Oxidation Process

research focus and difficulties in the field of water treatment. For all kinds ofrefractory industrial wastewater treatment, domestic and foreign research mainlyconcentrated in the printing and dyeing wastewater, petroleum wastewater，cokingwastewater, pharmaceutical wastewater and chemical wastewater. The wastewaterhave some come characteristics, such as high concentrations of pollutants, poorbiodegradability, toxicity, changes in water quality, and having significantcarcinogenic, teratogenic, mutagenic role of the "three letter". AOPs are effectivemethods for the treatment of the refractory organic wastewater, have the gooddevelopment and application prospect.In recent decades, AOPs have reached unprecedented prosperity. About AOPsresearch, there is no thesis using bibliometrics method. As more types of advancedoxidation technology, if just exploring one or several techniques, it can not be acomprehensive summary of the course of development of the AOPs. Therefore, thisthesis using literature Statistics Act, can comprehensive to reveal advanced oxidationtechnology development process, and the progress of the study of various advancedoxidation method.First of all, From the Chinese Periodicals text database and Wan fang Database,this paper, retrieve advanced oxidation technology literature, and compare. Then weanalyze the year’s distribution of literature and the number of important keywordsdistribution. We conclude: Advanced Oxidation study is divided into three stages,Start-up stage, the high-speed development stage, stable stage. Photo catalytic method,ozone oxidation, and Fenton method are research focus in the field of water treatment.Followed by, using literature Statistics Act, we found that the combination ofUV-Fenton photo catalytic method is now the most widely used. About thecombination of ozone oxidation method, the study of the ozone-activated carbon isearliest. But you can not deny that the O₃-H₂O₂also has greater prospects fordevelopment, is the research focus in the current ozone combinations.
