装置。 In sewage filtration equipment, a filter tank is filled with sand as a filter medium to form a sand layer, and raw water such as sewage mixed with suspended solids is passed through this sand layer, and the suspended solids are filtered during this time. A filtered water outlet and a suspended solids outlet are formed in the upper part of the filter tank, and an inlet for raw water such as sewage is formed in the lower part of the filter tank.
A raw water pipe is connected to this inlet, which sends the raw water to be introduced into the sand layer and at the same time induces fluidity in the sand layer to turn the sand layer into a fluidized bed. Filtration of sewage, etc., characterized in that a container is provided to receive the suspended solids, and an air lift pump is provided between the container and the suspended solids discharge port to suck up sand containing suspended solids accumulated in the container. Device.
