A wastewater advanced oxidation treatment device

Abstract

The application discloses a wastewater advanced oxidation treatment device, which comprises an adjusting tank and a reaction kettle, a forced circulation pipeline is arranged on the reaction kettle, a strong oxidant feeding device is connected to the forced circulation pipeline, a water outlet end of the adjusting tank is communicated with the forced circulation pipeline through a water inlet pipeline, a preheater is arranged on the water inlet pipeline, a water outlet pipeline is arranged at the bottom of the reaction kettle, the water outlet pipeline sequentially connects a wastewater cooler, a coagulation reaction tank and a sedimentation tank through the preheater, a steam pipeline is connected to the upper end of the reaction kettle, and a secondary steam cooler is connected to the steam pipeline. The application is provided with a wastewater preheater and a heater, the preheater is used for preheating fresh wastewater punched into the preheater by a water inlet pump by punching the reacted wastewater into the preheater by a drainage pump, so that the heat of the reacted solution is fully utilized, and the reacted wastewater is cooled, and heat loss is avoided.
