Abstract
Based on the present status and problems of sewage sludge disposal in Beijing,the development planning of the final disposal of sewage sludge is introduced,including heat drying + incineration,composting + agricultural use and lime drying + building materials.The feasibility of bio-carbon soil made from sewage sludge to restore the land is studied,and corresponding countermeasures are proposed as a reference for sludge disposal and utilization.
