摘　　要：蚯蚓生态滤池将蚯蚓创造性地引入到污水处理系统中,延长和扩展了微生物代谢链,强化了生态系统富集与扩散、合成与分解、拮抗与协同等多种自然调控作用,实现了污水污泥的同步高效处理。滤池出水可用作绿化和农田灌溉,蚓粪污泥含水率低,减量化稳定化效果显著,较好地解决了剩余污泥的处置问题。蚯蚓生态滤池工艺高效节能,具有鲜明的"生态平衡"和"环境友好"技术特色,符合可持续发展的理念,具有技术经济竞争优势,环境效益比较显著,具有良好的实际应用前景。Earthworm ecology filter is creative for the introduction of earthworm into the sewage treatment process, extending and expanding the biological chain.Synchronous efficient treatment of sewage and sludge in this artificial ecological system is achieved through enrichment and diffusion,synthesis and decomposition,antagonistic effect and synergism,and other natural regulation.The effluent could be used as virescence and irrigation. Earthworm fecal sludge contains low water, with significant stabilization and reduction effect, which could sovle rmnaining sludge disposal problems well.Earthworm ecology filter could save energy and operate efficien, with distinct ＂ecological balance＂ and ＂environmentally friendly＂ technical characteristics.This filter could meet the need of sewage sustainable development, with technical and economic competitive advantage, significant environmental benefits and good practical application prospects.
