An Overview on Resource Utilization of Sewage Sludge

Abstract

Abstract-The proper disposal of sewage sludge has been paid much attention. The traditional methods of sludge disposal include sanitary landfill, composting, thermo chemical treatment (including pyrolysis and combustion), and sea disposal. Urban sludge has the dual attributes of pollutants and resources. The resource utilization of sludge is the best way for sludge treatment and disposal. In view of the advantages and disadvantages of the traditional sludge treatment methods, this paper summarizes the research status of several typical resource utilization technologies. This paper expounds the latest research progress of the three aspects of energy regeneration and utilization of sludge, conversion and utilization of building materials and land use. The purpose is to promote the reform and further development of sludge utilization.

“…The two most common disposal techniques used worldwide are landfill and distribute on reclaimed land [9,10]. This type of disposal have various degrees of environmental effect including groundwater pollution that occurs from landfill leachates, soil contamination as well as odour emissions [11,12].…”
