Phosphorus Recovery from Charcoal of Sewage Sludge by Incineration Treatment
The phosphorus recovery from charcoal of sewage sludge by an incineration method was investigated. The charcoal of sewage sludge was mixed with alkali metal hydroxide and incinerated at 750 °C in aerobic conditions. The phosphorus was successfully recovered as an alkali metal phosphate from the incinerated ash through water extraction. The recovery rate of the phosphorus reached about 75% to 80%. The appropriate condition of the phosphorus recovery and composition of the recovered phosphorus were investigated.
