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.
