摘　　要：剩余污泥已成为污水处理厂亟待解决的棘手问题。虽然现有污泥减量技术众多,但或多或少都存在着技术或经济上的不足。蠕虫——L. variegatus应用于污泥减量具有较好的实际效果以及潜在的商业利用价值,因此,近年来受到人们关注。首先,介绍L. variegatus一般习性、对污泥减量的试验效果。然后,对L. variegatus应用于大规模连续系统的要点进行了技术分析。最后,对L. variegatus应用于实际污水处理厂污泥减量的技术与经济的合理性进行分析和估算。Disposal of waste sludge is an urgent problem for wastewater treatment plants. Although there are a lot of waste sludge reduction technologies, some technical and/or economic drawbacks are inevitably associ- ated with them. A worm, L. variegatus, has the simple and economic potential on sludge reduction, which is therefore studied. With this article, the general habit and the experimental results for sludge reduction of L. variegatus are firstly introduced. And then, the possibility of its application for continuous full-scale system is technologically analyzed. Finally, the technological and economical rationalities of L. variegatus on sludge reduction are evaluated.
