The filtered sewage is purified through the activated carbon plate 18. The sewage continues to flow into the lower part of the shell 2, and then the ozone generating box 21 and the pump bodies 22 on the left and right sides are turned on. The ozone generating box 21 starts to produce ozone gas, and the pump bodies 22 on the left and right sides are operated to respectively transport the treatment agent in the reagent box 20 and the ozone gas in the ozone generating box 21 to the two delivery pipes 23. The treatment agent and ozone gas in the two delivery pipes 23 are respectively discharged from the guide frame 24 to the lower part of the shell 2, and then the motor 6 is turned on. The output shaft of the motor 6 rotates to drive the second rotating rod 7 to rotate, and then the stirring plate 8 rotates to stir the sewage, so that the sewage is fully mixed with the treatment agent and the ozone gas. When the treatment agent is mixed with the sewage, the sewage is treated. When the ozone gas is mixed with the sewage, the color and odor in the water are removed and the dissolved oxygen in the water is increased, so as to achieve the purpose of improving the water quality. After the sewage treatment is completed, the water outlet 25 is opened for drainage.
