[0026] During use, sewage enters the box body 1 through the water inlet pipe 2. After entering the box body 1, the sewage will pass through the filter frame 7 and fall to the bottom of the box body 1, while the garbage in the sewage will be intercepted by the filter frame 7 and remain in the filter frame 7. Then, the box cover 5 is opened through the locking assembly 6, and the medicine is added into the box body 1. The medicine and sewage are stirred and mixed by the stirring mechanism 13. Finally, the valve 4 is opened to allow the sewage that has been preliminarily treated in the box body 1 to be discharged through the drain pipe 3.
