The invention relates to a treatment system and an operation method of phosphorus-containing organic wastewater. A chemical phosphorus removal system is combined with an aerobic biochemical system, thus forming a system that removes phosphate and organic matters in the effluent of an aerobic removal system. The chemical phosphorus removal system consists of a chemicals feeding system, a mixed reaction pool, a sedimentation pool, a residual sludge refluxing system and a chemical sludge refluxing system. The aerobic biochemical system consists of an aerobic contact oxidation system and an aerobic activated sludge system. During the process of chemical phosphorus removal, sulfide and part of the organic matters can be removed simultaneously, thus causing the subsequent aerobic process to run stably and reducing running cost thereof.
