Analysis on Characteristics and Resource Utilization of Sewer Sludge in Hefei City
Sewer sludge is the sediment cleared during drainage system maintenance operations,and the drainage pipe network and drainage pump station are the main sedimentation nodes of sewer sludge,and poor dredging will affect its normal operation.In order to effectively improve the treatment capacity and resource utilization rate of sewer sludge in Hefei City,it is necessary to combine the collection method and moisture content of sewer sludge,analyze the characteristics of domestic sewer sludge,study the current situation of sewer sludge treatment in Hefei City,and explore the disposal methods of sewer sludge treatment products.After testing,the moisture content of the sewer sludge from some rainwater wells in Hefei City is relatively low,less than 60%.In order to improve the utilization rate of resources,it is necessary to construct and improve sewer sludge treatment facilities,improve the precision and purity of particle classification,and separate and produce construction sand that meets various building material standards.At the same time,it is necessary to combine the resource utilization of products,determine the deep separation process,and use properly classified sewer sludge particles as building materials to achieve sustainable development.
