摘要
The production of municipal sludge is huge,and the sludge contains a large quantity of organic matter and nutrient elements. In this study,the development status of sludge compost at home and abroad was briefly described,and the environmental risk of land use of sludge compost was summarized. Meanwhile,the utilization direction of sludge compost was proposed. The use of sludge compost in urban green soil and forestry soil is one of effective ways to solve the problem of municipal sludge. It also provides ideas for the disposal of domestic sludge.
