蚯蚓污泥堆肥的研究进展

Research Progress on Earthworm Sludge Composting

近年来,蚯蚓被广泛应用于污泥堆肥应用中,这种方式成为一种高效且环保的生物降解工艺。概括介绍了焚烧、厌氧消化、好氧发酵等常见的城市污泥处理方式。通过比较研究法和案例分析法等研究方法针对污泥堆肥环境中4个影响因素:温度、含水率、重金属、C/N对蚯蚓的影响,总结了部分蚯蚓污泥堆肥技术的发展现状,为蚯蚓污泥堆肥技术提供一定的参考依据。

In recent years,earthworms have been widely used in sludge composting,which has become an efficient and environmentally-friendly biodegradation technology.This article summarizes common urban sludge treatment methods such as incineration,anaerobic digestion and aerobic fermentation.By research methods such as comparative research and case analysis,this paper summarizes the development status of some earthworm sludge composting technologies in veiw of the impact of four influencing factors in the sludge composting environment:temperature,moisture content,heavy metal and C/N on earthworms,which provides a certain reference basis for the earthworm sludge composting technology.
