| Abstract: | Based on the shortage of phosphorus resources, the status of sewage sludge disposal and the flow characteristics of phosphorus in life, the necessity of recycling phosphorus from sewage sludge is analyzed. The methods of releasing phosphorus by solid phase to liquid phase from sewage sludge were discussed, such as anaerobic digestion, ozone oxidation, heat treatment, ultrasonic dissolution and burning extraction, etc. Furthermore, the theories and research status of methods in recovering phosphorus from sewage sludge were summarized, including chemical precipitation, adsorption-desorption, burning heat treatment and nanofiltration. Finally, the research, development and application prospects of release-recovery technology of phosphorus from sewage sludge were discussed. |
