Research Progress on Treatment,Disposal and Resource Utilization of Municipal Residual Sludge
With the continuous increase of sewage treatment capacity in China,the surplus sludge production is also increasing,which is easy to cause safety risks and the economic burden of disposal.This paper summarizes the treatment methods,traditional disposal methods and resource utilization methods of residual sludge in urban sewage treatment plants from the aspects of relevant technologies involved in the treatment and disposal process of residual sludge,their characteristics and effects,and forecasts the prospects of the treatment and disposal technologies of residual sludge,aiming to further improve the treatment rate and utilization rate of residual sludge.To achieve the reduction of sludge,harmless,stable and resource.
