Current and Prospective Research on Engineering Application of Sludge Aerobic Composting Technology
Municipal sewage sludge contains a large number of nutrients,such as nitrogen,phosphorus,potassium and organic matter,which has the potential to produce agricultural fertilizer and soil amendment.The use of municipal sewage sludge by aerobic composting for the formation of fertilizer and input into land use,is one of the ways of sludge harmless and resource utilization.And through mechanical devices and equipment to assist aerobic composting technology to improve composting efficiency,is currently more advanced,but also very common treatment method.This paper reviews the research status of municipal sludge aerobic composting technology,analyzes and compares several existing composting technologies and mechanical equipment,and looks forward to the development of such mechanical equipment and technologies in the field of sludge aerobic composting.
