[0026] The top of the treatment box 2 can be sealed and protected by the fixing plate 10 and the fixing plate 2 17. The wastewater pipe 1 passes through the filter plate 11, so that the wastewater can reach the bottom of the filter plate 11. The downward movement of the filter plate 11 can be used to filter the wastewater. The water pump 7 can accelerate the flow of the wastewater, so that the filtered wastewater can be quickly extracted. The servo motor 21 can drive the lead screw 22 to rotate stably, thereby driving the support plate 9 to reciprocate inside the treatment box 2.

[0029] The reduction motor 16 can be used to drive the stirring rod to rotate. The stirring blade 15 rotates with the stirring rod to accelerate the reaction between the hydrogen peroxide solution and the wastewater, oxidize the wastewater, and reduce the content of organic matter in the wastewater. The nozzle 19 is installed on the outer ring surface of the auxiliary disk 18. The use of multiple nozzles 19 can improve the uniformity of spraying the hydrogen peroxide solution. The connecting pipe 20 is convenient for delivering the hydrogen peroxide solution into the cavity of the auxiliary disk 18. Since the auxiliary disk 18 is rotatably connected to the stirring rod, the auxiliary disk 18 will not be disturbed when the stirring rod rotates.

The positioning plate 4 can limit the installation of the ultrafiltration membrane assembly 13, which is convenient for the installation and removal of the ultrafiltration membrane assembly 13 inside the processing box 2.

[0030] The method of use and working principle of the device are as follows: first, wastewater enters the cavity on the left side of the partition from the wastewater pipe 1, and the filter plate 11 is driven downward by the hydraulic push rod 12 to perform preliminary filtration on the wastewater. The filtered water reaches the top of the filter plate 11, and the stains and sediments remain under the filter plate 11. Then, the wastewater is discharged into the cavity on the right side of the partition by the water pump 7, and the solenoid valve on the drainage pipe at the bottom of the collection bucket 14 is closed. The hydrogen peroxide solution is introduced into the auxiliary disk 18 by the connecting pipe 20, and then sprayed out through the nozzle 19 to react with the wastewater in the cavity for oxidation. When the solution is sprayed out, the reduction motor 16 drives the stirring rod to rotate, thereby driving the stirring blade 15 to rotate, accelerating the reaction of hydrogen peroxide and wastewater, and the excess gas is discharged through the pressure relief valve 6. The wastewater after the reaction is discharged from the drain pipe and is filtered again by the ultrafiltration membrane assembly 13 to complete the overall treatment of the wastewater. The concentration of hydrogen peroxide is 0.15%, which will not affect the use of the ultrafiltration membrane assembly 13. The sludge pump is connected to the sewage pipe 3 to quickly discharge the sediment inside the processing box 2, and the ultrafiltration membrane assembly 13 can be removed and replaced by moving the positioning plate 4.
