Research progress on the Treatment of Municipal Sludge Based on Earthworm Farming Technology
With the continuous advancement of urbanization in our country,the amount of urban domestic sewage has increased sharply,leading to a surge in the amount of municipal sludge generated,which has a huge impact on the urban ecological environment.The re-duction,harmlessness,stabilization,and resource utilization of municipal sludge have become one of the urgent environmental problems to be solved.The author introduces the research progress of using earthworm farming technology to treat municipal sludge from the as-pects of earthworm species,temperature,sludge type,and sludge moisture content,focusing on the reduction and resource utilization of municipal sludge.
