SETTLING FILTRATION TANK, SEWAGE TREATMENT EQUIPMENT USING THE FILTRATION TANK AND METHOD THEREOF

摘要

PURPOSE: A settling filtration tank, a sewage treatment equipment using the filtration tank and a method thereof are provided, which can produce settling tank and filtration tank in a monolithic combined tank and so can maximize space utilization, increase settling rate by providing settling tank of lamella constitution and increase treatment efficiency of SS. CONSTITUTION: The system comprises the followings: (i) a sludge concentration tank (10) that is set beneath a sludge settling tank (30) and has a conical bottom for collecting sludge (S) contained in sewage and for discharging; (ii) a sludge settling tank (30) that is installed on the sludge concentration tank (10) with an angle to the horizontal plane, in which lamella pipes (32) are installed at a fixed distance; and (iii) a sludge filtration tank (50) that is set above the sludge settling tank (30) in which a filtering device (70) and sludge filtering tank (50) are installed.
