[0002] Sewage refers to water discharged from daily life and production that has been contaminated to a certain extent. Water that has lost its original function is simply called sewage.

[0003] For example, the Chinese patent with publication number CN220098710U discloses a catalytic oxidation sewage treatment device, which belongs to the field of sewage treatment technology and includes a support rod, a rotating motor fixedly installed on the top surface of the support rod, the output end of the rotating motor passes through the support rod and is fixedly connected to a rotating shaft, the free end of the rotating shaft is fixedly connected to a limit plate, an air intake box is provided on one side of the support rod, the top surface of the air intake box is rotatably connected to a stirring box for catalytically oxidizing sewage, and a rotating wheel is fixedly provided on the peripheral side of the stirring box, a belt is provided between the rotating wheel and the rotating shaft, and a fixed column is provided in the inner cavity of the stirring box, and stirring rods are symmetrically installed on the peripheral side of the fixed column, the bottom end of the fixed column is fixedly installed on the top surface of the inner cavity of the air intake box, and a plurality of stirring rods are installed with hanging plates on the opposite ends. This catalytic oxidation sewage treatment device solves the problem that ozone cannot be evenly mixed with sewage, thereby improving the efficiency of the catalytic oxidation sewage treatment device in mixing sewage and ozone.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings during use. For example, several nozzles in the device are located near the bottom of the air inlet box, which causes the wastewater near the bottom of the device to be exposed to ozone first, while the wastewater near the top of the device is not immediately exposed to ozone, resulting in a slow mixing of wastewater and ozone. In addition, the device uses only one filter plate, which may not filter some dirty wastewater thoroughly enough. In view of this, we propose a catalytic oxidation wastewater treatment device. Utility Model Content

[0006] The purpose of the utility model is to provide a catalytic oxidation sewage treatment device to solve the problems raised in the above background technology.

[0015] In the above technical solution, further, the output shaft of the motor is rotationally connected to the L-shaped plate.

[0018] In this technical solution, several filter plates 2 can filter the impurities in the sewage for the first time, so that some impurities remain on the filter plate 2.
