The sewage enters the tank 1 through the water inlet 2, and particles are blocked by the grating 31 and accumulated in the water inlet 2 and are positioned at the bottom of the grating, as shown in fig. 2, the particles have a tendency to shift toward the grating as the sewage flows toward the grating. When cleaning is needed, an operator pushes the connecting rod mechanism, the bottom of the grating is displaced towards the impurity discharging port, and the displacement direction is opposite to the flowing direction of sewage in the water inlet. The grid 31 pushes the accumulated particulate matter toward the drain 201 through which the particulate matter exits the water inlet as shown in fig. 3. A collection container may be placed under the impurity discharging port 201 to collect the particulate matters falling from the impurity discharging port. After the cleaning of the particulate matters is completed, an operator pulls the link mechanism, the link mechanism pulls the grating 31 to reset, and simultaneously, pulls the valve plate 202 to reset, and the valve plate closes the impurity discharging port 201.
