摘　　要：介绍了中晚期垃圾渗滤液的生物处理技术现状,归纳了各种生物处理方法的技术特点及其处理难降解有机物的效果。分析了目前常用的生物及物化处理技术成本。认为中晚期垃圾渗滤液中含有的有机物大都难于生物降解,仅采用生物法处理效果有限,而与高级氧化等物化法联用虽然能取得较好的处理效果,但会大幅增加处理成本。认为应充分发挥生物法的技术优势,筛选可利用或促进利用难降解有机物的高效微生物,提高中晚期垃圾渗滤液的可生化性,针对中晚期垃圾渗滤液氨氮含量高的特点,也可与反硝化等脱氮工艺相结合,实现同步、深度脱氮、除碳,期望未来扩展生物处理技术及工艺的应用领域,降低中晚期垃圾渗滤液的处理成本。The technical state of biological treatment for refractory organic treatment in mature landfill leachate was introduced. The technical characteristics of various biological treatment methods and the refractory organic matter treatment efficiency were summarized. The current technical costs of biological and physicochemical processes were also analyzed. It was concluded that the organic matter contained in mature landfill leachate was mostly difficult to be biodegraded. The biological treatment effect was limited, although combined with advanced oxidation and other physicochemical methods could achieve better treatment effect, and the treatment cost could increase greatly. It should give full play to the technical advantages of biological method, and screen efficient microorganism for refractory organic degradation, to ir0prove the biodegradability of mature landfill leachate. Aimed at the characteristics of high ammonia nitrogen content in mature landfillleachate, it could be combined with denitrification nitrogen removal process to realize nitrogen and carbon synchronously and deeply removal. It be expected to extend the application area of biological treatment technology, and decrease the cost of mature landfill leachate treatment in the future.
