A plurality of distribution ports 5 are arranged on the side wall of top cover 2 and surround water inlet pipeline 4, the aperture of a plurality of distribution ports 5 is same, according to fluid dynamics principle, when water flows into cylinder 1 from high water inlet pipeline 4, due to the taper design of the end of water inlet pipeline 4, water flow rate increases, leading to the pressure drop of the end of water inlet pipeline 4, creating a negative pressure area, that is, vacuum effect, so that the sewage around distribution port 5 is affected by pressure difference and is attracted into distribution port 5, and then flows into cylinder 1 through the negative pressure area of the end of water inlet pipeline 4, realizing the guidance and distribution of sewage, ensuring that the sewage can be evenly distributed when entering cylinder 1, improving the mixing effect in the pool body, promoting hydrolytic acidification reaction.
