SEWAGE TREATMENT EQUIPMENT

摘要

PURPOSE: Provided is a sewage treatment equipment capable of surely exhibiting sewage treatment capacity. CONSTITUTION: The sewage treatment process comprises transferring treated water in an activated sludge vessel(61) to an electrolytic tank(70) employing electrodes(71,72); subjecting the transferred treated water into electrolysis in order to supply iron ion or aluminium ion to the electrolytic tank(70) thereby coagulating phosphorous compounds in the treated water; and transferring the resulting coagulated floc to the activated sludge vessel(61) employing a magnet(61a) in order to attract the coagulated floc of the phosphorous compounds to the magnet(61a).
