蚯蚓生物滤池的研究与应用进展

蚯蚓生物滤池是根据蚯蚓具有提高土壤通气透水性能和促进有机物分解转化等生态功能而设计,是一种通过滤料截留及蚯蚓和微生物分解利用污水、污泥中的有机物和营养物质的生态型污水污泥同步处理技术。介绍了蚯蚓生物滤池的工作原理和特点,以及在国内外的研究和应用进展情况。经过十几年的相关研究,目前蚯蚓生物滤池的应用已涉及小城镇污水处理、农村生活污水处理和污泥处理等多个研究方向,使得蚯蚓生物滤池的理论研究和实际应用都得到了一定的发展。

Research and Application Progress of Vermibiofilter

Vermibiofiher is designed according to that the earthworms have ecological functions of improving soil aeration and water infiltration and promoting decomposition and transformation of organic matters. It is a simultaneous wastewater and sludge treatment technology in which the organic matters and nutrients in wastewater and sludge are trapped by filtering materials and decomposed by earthworms and microorganisms. The working principle and characteristics of vermibiofilter and its research progress at home and abroad are introduced. After more than ten years studies, vermibiofilter has been applied for the treatment of wastewater from small towns, rural domestic sewage and sludge, which enriches the theo-ry and practicability of vermibiofilter.
