Abstract：The remaining sludge from sewage treatment contains alarge amount of phosphorus source.Recycling and utilizingthisportionof phosphoruscanhelpalleviate thecurrntsituationofphosphorusresourcescarcity.Theprerequisite forachievingphosphorus recycling is topromote thereleaseofphosphorus fromsludge.Therefore，thisarticlesummarizes three treatmentmethodsforposphoruseleasefromsudge：psical，hemical，andiologicaltreatment.Itrieflyoutlies the principles，dvantages，nddisadvantagesofachmethod，providingateoreticalbasisforthersearchonposporus recoveryand utilization from sludge.It also loks forwardtotheeconomic eficiencyof the practical application and promotion of sludge resource utilization.
