我国蚯蚓生物滤池处理垃圾渗滤液的应用难点及对策建议

Application Difficulties and Strategies for Landfill Leachate Treatment with Earthworm Biofilter in China

由于垃圾渗滤液污染程度高,污染成分复杂,一直以来是治污的难点。蚯蚓生物滤池是一种新型的污水净化技术,该技术具有良好的经济和生态效益,应用前景广阔。在我国,利用蚯蚓生物滤池净化处理垃圾渗滤液的研究处于起步阶段,由于垃圾渗滤液的高污染性和蚯蚓生物滤池本身的局限性,使得该方面的研究进入瓶颈期。严格进行垃圾分类处理,将垃圾渗滤液与城市污水合并处理,探究工艺组合处理技术,培育和筛选更合适的蚓种,优化滤池结构,选择合适的净化工艺清理滤池等能够促进蚯蚓生物滤池净化处理垃圾渗滤液技术的研究进展和应用。

The degree of the landfill leachate pollution is pretty high and its pollution elements are very complicated with the result that this as- pect has been a hardest point of all the time in pollution controlling. However, earthworm biofilter is a new technology for sewage purification which has good economic and ecological benefits, so it has huge application prospect. In China, the study of earthworm biofilter is in a start-up phase. Because of the high polluting of landfill leachate and the limitation of earthworm biofilter itself, this study steps into the bottleneck period. What we can do at the present is making the separation of garbage disposal strictly, incorporating the garbage leachate and urban wastewater to deal with, exploring the combined processing technology, cultivating and selecting more suitable vermis, optimizing the filter structure and choo- sing the appropriate cleaning process cleaning filter and so on. Above-mentioned can promote the development and application of the technology.
