水蚯蚓在污泥减量中的研究进展

Research Progress of Water Earthworm in Sludge Reduction

在城市化的过程中,人口不断膨胀,工业废水与生活污水的排放量日益攀升,剩余污泥的产出量也随之迅速增加,日渐成为污水处理厂的沉重负担,从源头上削减污泥产量则意义重大。利用微型生物的捕食作用进行污泥减量,清洁无污染,是一项实现污泥源头治理的绿色技术。本文综述了近些年利用水蚯蚓进行污泥减量技术的研究与应用,从多个角度探讨该方法的优势和弊端,为该技术的进一步推广提供指导。

In the process of urbanization, population expansion, industrial wastewater and domestic sewage emissions rising,excess sludge output is increasing rapidly becomes more and more heavy burden of sewage treatment plant, from the source to reduce sludge production is of great significance. Using micro organism to reduce the amount of sludge, clean and pollutionfree, is a green technology to control the source of sewage sludge. This paper summarizes the research and application of sludge reduction technology using water earthworm in recent years, discusses the advantages and disadvantages of this method from several angles, and provides guidance for the further promotion of the technology.
