Background technique

The fine grating is a solid-liquid separation equipment that is composed of a group (or multiple groups) of parallel metal grating bars and frames, and is installed on the inclined channel to continuously remove the debris in the fluid. The fine grating is used to remove the coarse grating. After intercepting the coarse suspended solids, the smaller suspended solids in the sewage are further intercepted to ensure the normal operation of the subsequent treatment facilities. The fine grating is a solid-liquid separation equipment that can continuously remove the debris in the fluid.
