The invention discloses a method for recovering polyvinyl chloride (PVC) particles from PVC centrifuged waste water. The method adopts a centrifuge, a washing tower, an inclined plate fast depositing tank, a pneumatic continuous sand filter, a release tank and a biochemical treatment device, wherein the centrifuge, the washing tower, the inclined plate fast depositing tank, the pneumatic continuous sand filter, the release tank and the biochemical treatment device are connected orderly. In PVC production, most of waste water produced by the centrifuge directly enters into the inclined plate fast depositing tank and the pneumatic continuous sand filter. A small amount of the waste water is fed back to the washing tower to replace primary water to be utilized as washing water. The washing water is utilized for capturing PVC particles in exhaust gas from an induced draught fan outlet. The washed waste water enters into the inclined plate fast depositing tank for precipitation and then enters into the pneumatic continuous sand filter for filtration. The filtered waste water is collected by the release tank and then is fed into the biochemical treatment device for treatment by a pump. The method obviously improves a recovery rate of PVC particles in waste water, greatly reduces suspension content of waste water, and produces good economic benefits, social benefits and ecological benefits.
