英文摘要： The pollution of highly concentrated pharmaceutical wastewater is one of the huge environmental problems in the process of industrialization of our country. Focusing on the problem of covering both the advantages of high activity and treatment cost for catalytic ozonation in the pharmaceutical wastewater treatment, the following aspects would be carried out in the application. Firstly, we invent the ways of magnetic CeO2 nanoparticle production by way of theory analysis, calculation and experiment. Secondly, we study the structure and reaction mechanism of the catalyst interface and the aqueous solution, explores the surface chemistry, electronics structure and property of point defects (oxygen vacancies) of catalyst, clarify the relationship among the catalysis structure, function and preparation, achieve the manipulation the activity of the catalyst at the fundamental level. Thirdly, optimize the process integration, explore the interaction of the factors, analyze the process of organic pollutant degradation, clarify the reaction mechanism of magnetic CeO2 nanoparticles catalytic ozonation, and provide the fundamental data and theory reference for the application of catalytic ozonation with magnetic CeO2 nanoparticles in pharmaceutical wastewater pollution control.
