蚯蚓生物滤池技术处理污水研究现状

Research Status of Wastewater Treatment by Vermifilter

随着社会的发展,小城镇水环境污染越来越严重。蚯蚓生物滤池属于污水处理生物膜法一种,是基于普通生物滤池开发的一项实用性技术。其具有工艺简单,管理方便,占地面积小等优点,是一种适合应用于小城镇及农村污水分散式就地处理的技术。概述了蚯蚓生物滤池的基本原理;介绍了蚯蚓生物滤池处理污水的作用效果;从蚯蚓生物滤池运行角度,总结了蚯蚓生物滤池运行的工况条件;并且对蚯蚓生物滤池技术的应用进行了展望;最后,为蚯蚓生物滤池的后续研究提供了建议。

With the development of society, water pollution in small towns is becoming more and more serious. Vermifilter is a kind of biofilm method. It is a practical technology based on Biofilter, which has the advantages of simple process, convenient management, small floor area and so on. It is a kind of technology suitable for the small town and rural sewage decentralized local treatment. The basic principle of earthworm biofilter was summarized. The effect of earthworm biological filter on sewage treatment was introduced. The operating conditions of earthworm biofilter were summarized from the operating point of earthworm biofilter. The application of earthworm biofilter technology was prospected. Suggestions were proposed for the future research direction of Vermifilter.
