包括抗生素在内的医药品与个人护理用品（PPCPs）的广泛生产和使用，已经在世界范围内造成严重的环境污染。现有处理技术无法有效治理。基于电子束辐照技术处理效率高、对有机物污染物降解彻底，没有二次污染等优点，本项目计划采用辐照技术处理典型药物废水，分析药物辐照降解动力学，并研究各种环境因素的影响。同时开展辐照降解机理研究，特别要开展辐照药物物理化学阶段特性方面的创新性研究，利用脉冲辐解和激光光解等瞬态时间分辨分析手段，进一步阐明激发分子、离子、自由基与污染物等作用特性及相关降解机理。另外开展与药物光解特性进行对比研究，结合光解情况，为建立有效的高级氧化处理典型药物废水提供重要的技术支持。另外通过采用量子化学等计算方法，对有机污染的降解过程进行理论计算，并结合降解机理，建立有效的辐照处理装置。研究成果可为典型抗生素药物的环境归趋、环境风险评估提供科学依据，并为污染控制提供有有效技术支撑。

Pharmaceuticals and Personal Care Products (PPCPs) has caused serious environmental pollution in the world, for it widespread production and use. One important class of pharmaceuticals which has received recent consideration is antibiotics. The existing biological treatment technology and conventional advanced oxidation technology cannot treat such new pollutant effectively. Therefore, to seek an efficient means of degradation is the hot topic in environmental research..Due to some compounds under the photolysis can produce higher toxic substances under the photolysis, the electron beam irradiation technology as advanced oxidation treatment technology is a very promising treatment technology. Other research shows that this technology has some advantages, such as degradation efficiency is high, the degradation of organic pollutants is very thorough, it has no secondary pollution, etc. But there is no industrial scale sewage irradiation processing application in the domestic at present. To study whether this technology is effective for treatment of typical drug wastewater, first of all is to analyze irradiation degradation kinetics of drugs, and study the influence of various environmental factors. We need to study the irradiation degradation mechanism at the same time, in particular, to research the phase characteristics of physical and chemical properties of target antibiotics innovatively. To analyze its nanosecond level even picosecond level reaction condition using pulse radiolysis and laser photolysis transient time-resolved analysis method, further to clarify degradation characteristics and the related mechanism that pollutant interact with trigger molecules, ion sand free radicals. And to provide important technical for establishing an effective advanced oxidation typical drug wastewater treatment, comparing with drug photolysis properties study and combining the condition of photolysis. The research adopted quantum chemical calculation method to finish theoretical calculation on the degradation of organic pollution, thereby improve the analysis of the experimental results. Combining with the related degradation mechanism, we can establish effective radiation processing equipment. The project of the research results will provide scientific basis to the environmental and health risk assessment of the typical antibiotic drugs. At the same time, it can be applied to the advanced oxidation technology to deal with drug pollutants such as water pollution control areas, provide effective technical support for the drug pollution control.
