[Background of the Invention] A plurality of filter elements, each of which has a slit groove between plates of a large number of rotating plates fitted to a rotary shaft, are arranged such that adjacent ones of the filter elements are fitted into the slit groove of the other. A type of solid-liquid separation device that is arranged in a treatment tank in a crosswise manner is known. However, in this type of solid-liquid separation device, the entire outer peripheral surface of the rotary plate is not utilized, and only a part of the outer peripheral surface functions, so that the processing capacity is poor. In addition, as a drawback of the conventional multi-disc solid-liquid separation device, when the raw water concentration such as scum is low, the treatment amount is rate-controlled and the function cannot be fully exerted. It is necessary to supply it into the processing tank after concentrating it to the level.
