The V-shaped filter tank is a filtering device commonly used in sewage treatment, the name is obtained because the water inlet grooves at two sides of the tank are in a V shape, water inlet of the existing V-shaped filter tank enters the filter tank usually through water distribution holes distributed on a V-shaped groove weir, and water inlet points entering the filter tank cannot be uniformly distributed at all parts of the filter tank due to the limitation of the V-shaped groove fixed at two sides of the V-shaped filter tank and the size of the groove weir, so that the local hardening of the filter tank is serious. Therefore, the filter tank needs to be backwashed after running for a period of time, and for sewage with large flow and high suspended matter content, the backwashed period of the filter tank is often required to be shortened, and the backwashed time is increased, so that the filtering efficiency of the filter tank is reduced, and the running cost is increased.
