[0032] Working principle: The oxidizing agent can be poured into the reagent tank 2, and the wastewater can be poured into the treatment tank 1. The oxidizing agent in the reagent tank 2 can be pumped into the main pipe 401 by the liquid pump 8, and sprayed out through the nozzle 404 at one end of the branch pipe 402. At the same time, the driving wheel 1001 is driven to rotate by the motor 9, thereby driving the belt 1003 and the driven wheel 1002 to rotate, and further driving the main pipe 401 to rotate. The main pipe 401 and the branch pipe 402 are used to stir the wastewater while spraying the oxidizing agent into the wastewater.
