The invention discloses a PPCPs type waste water processing system. The PPCPs type waste water processing system comprises a water inlet device, a membrane distillation device, a water circulation device and a water collection device. The water inlet device is used for leading PPCPs type waste water in the membrane distillation device. A graphene bismuth tungstate PVDF photocatalysis membrane is arranged in the membrane distillation device. The membrane distillation device is used for generating a catalytic reaction through the graphene bismuth tungstate PVDF photocatalysis membrane under triggering of visible light so as to degrade waste water, and then driving water vapor to penetrate through the graphene bismuth tungstate PVDF photocatalysis membrane and enter the water circulation device by heating the two sides of the graphene bismuth tungstate PVDF photocatalysis membrane to generate the vapor pressure difference. The water circulation device is used for liquefying the water vapor penetrating through the graphene bismuth tungstate PVDF photocatalysis membrane into water through water circulation, and then bringing the water into the water collection device. The water collection device is used for collecting the processed water. The PPCPs type waste water processing system can process waste water in a harmless mode.
