摘　　要：The production of urban sludge is huge,and the anaerobic digestion of sludge is one of the important methods for sludge treatment at home and abroad.The products of sludge digestion can be further used as resources.In this study,biogas slurry,as one of products of sludge digestion,was deeply treated by intermittent and continuous aeration,and the feasibility of using biogas slurry in land was discussed.Meanwhile,the processing cost was analyzed.This study can provide support for the deep utilization of sludge digestion products.The production of urban sludge is huge,and the anaerobic digestion of sludge is one of the important methods for sludge treatment at home and abroad.
