我国高速城市化下的垃圾污染，以及垃圾渗滤液带来的生态环境污染一直备受关注。传统的垃圾渗滤液湿式氧化处理方法，存在反应条件苛刻、有机物降解不彻底、药剂成本高等缺点。本项目拟采用紫外光诱导催化湿式氧化方法降解渗滤液，揭示紫外光对催化剂、氧化剂、渗滤液光敏物质的诱导催化作用规律，更好地指导垃圾渗滤液降解工艺参数的选择和优化，提升紫外催化湿式氧化方法的降解效能，且反应条件温和、设备投资更低、处理效果更稳定。运用急性毒性、内分泌干扰毒性、遗传毒性评价方法相结合，通过对渗滤液中典型环境激素的降解路径、中间产物生物毒性评价和渗滤液成分影响研究，探析垃圾渗滤液生物毒性减量的原理。所采用的生物毒性评价方法更直接贴近垃圾渗滤液毒性和环境污染的真实情况，解决了垃圾渗滤液化学指标分析复杂、无法表征生物毒性的难题，为进一步解决垃圾渗滤液无害化和控制生态污染风险提供了理论基础。

The garbage pollution under the high-speed urbanization in China, as well as landfill leachate has brought the pollution to the ecological environment. It has been always paid much attention to and become an international research focus. There are many shortcomings in traditional wet oxidation method for treating landfill leachate, such as hard reaction conditions, high temperature and pressure to start the reaction, incomplete organic matter degradation and higher reagent cost. This project intends to adopt UV light to induce catalytic wet oxidation of landfill leachate. Revealing the law of UV light how to induce catalyst, oxidant and photosensitive material from leachate is very important for better guiding the degradation process parameter selection and optimization of leachate, additionally improving the efficiency of UV-catalytic wet oxidation process. Moreover, the UV catalytic process can start reaction under atmospheric temperature and pressure, occupy lower equipment investment and degrade the leachate more stably. Use acute toxicity and endocrine disruptor toxicity, genetic toxicity evaluation method to evaluate reduction principle of biological toxicity by UV-catalytic wet oxidation process of leachate. Meanwhile, the combination research of the degradation path of typical environmental hormone in leachate, intermediate biological toxicity evaluation and leachate composition impact factors will help deeply discovering the reduction principle of biological toxicity of the leahcate. Finally, discovering the relationship between the process parameter control and biological toxicity reduction can help establishing an economic and efficient landfill-leachate biological toxicity reduction method. This project provides a theoretical basis for further solving the harmless and ecological risk control of the landfill leachate.
