The coarse debris is intercepted by a coarse screen, and the fine debris is intercepted and removed by a fine screen. In the existing treatment process, a rotary drum fine screen is often used to remove fine debris. That is, the centrifugal force between sewage and impurities is different, so that the fine debris adheres to the surface of the grid drum, and the sewage flows away through the gap of the grid drum. The debris attached to the surface of the grid drum is separated from the surface of the grid drum to the outside by the scraper plate.
[0003] The existing rotary drum type fine grid has steel bars evenly arranged on the outside, and the steel bars are used to reinforce the fine grid inside. However, the steel bars are usually welded to the support ring, so there are the following disadvantages:
