COAGULATING AND SEPARATING APPARATUS

摘要

COAGULATING AND SEPARATING APPARATUS A coagulating and separating apparatus is provided with a coagulating and separating tank (1) into which raw water is introduced. The raw water flows from a mixing tank (2) to the coagulating and separating tank (1) through a raw water introducing pipe (3), an arrangement (4) for adding high specific gravity, and a raw water introducing pipe (5). A current generator (11) is provided in the coagulating and separating tank (1) for stirring water to be treated to generate water current. Under the coagulating and separating tank (1), a sludge discharge opening (13) and a sludge collection box (14) are provided... The sludge in the sludge collection box (14) is transferred to a separator (8) through a sludge transfer pipe (15). The separator (8) separates material with high specific gravity from the sludge. and supplies it into the (arrangement (4) for adding the material with high specific gravity. (FIG. 1)
