[0012] The beneficial effects of the present invention are as follows: (1) The present invention provides an oblique inlet to guide sewage into the horizontal pipe. During the falling process, the gravitational potential energy is converted into kinetic energy, so that the sewage can move in the horizontal pipe. During the movement of the sewage, impurities in the sewage may block the pipe. Under the impact of the water flow, the rotating shaft rotates, thereby driving the sliding groove to rotate, and then the centrifugal force generated by the rotation drives the sliding block to slide up and down.

During the rotation process, the centrifugal force generated causes the chemical agent in the medicine box to flow out from the medicine outlet and combine with the sewage, thereby generating a chemical reaction to solidify the harmful components in the sewage.
