Abstract

For the sake of the shortage of phosphorus resources and the present situation of municipal sludge treatment and disposal, the necessity of recovery of phosphorus from municipal sludge is analyzed, whereas the methods of phosphorus releasing from solid phase to liquid phase in sewage sludge, such as anaerobic digestion, ozone oxidation, heat treatment, ultrasonic dissolution and alkaline hydrolysis, were discussed in this paper. And then the theories and methods of phosphorus recovering from sewage sludge were summarized, including chemical precipitation, adsorption - desorption, burning heat treatment and nanofiltration. Finally, the research development and application prospects of phosphorus release - recovery technology from sewage sludge were also proposed.
