| Abstract: | Chemical phosphorus removal is an effective approach to controlling eutrophication and recycling phosphorous resource from waste water. The mechanisms of three major phosphorus removal reagents，such as ferric salt，aluminum salt and lime，were presented，and the influence factors of these three reagents，including pH，dosage，optimal dosing points and economic analysis，were also discussed. The processes of pre-chemical-aid，synergic-chemical-aid，post-chemical-aid and bypass-chemical-aid phosphorus removal technologies were summarized. The adsorption and crystallization phosphorus removal new process was introduced，and the prospect of recycling phosphorous resource as the development orientation of phosphate removal process in the future was presented. |
