Abstract

PURPOSE: To efficiently purify sewage with a simple device by bisecting a purifying tank to upper and lower halves, and removing solids from the sewage by supplying the sewage being given swirling flow into the lower chamber of the tank then conducting the same in upward current into the upper chamber provided with contact materials.
CONSTITUTION: If the sewage flowed into an inflow tank 10 is blown into the lower chamber B of the tank through a water feed pipe 12 while swirling flow is being thereto by an underwater aerating pump 11, those of larger particles or of heavier specific gravities in the sludge of the sewage settle directly or their own weights while being flowed along the circumferential surface of a purifying tank 1, by the swirling flow, and they are collected in a sludge collecting tank 3. Those which are relatively light or of small specific gravities are conducted together with the sewage into the upper chamber A of the tank through the holes of a middle bottom 6, and at the time when they move in upward current in contact filter media 7, they are oxidized and purified by purifying micro-organisms on the filter surfaces. The purified water overflows from the top end of the tank and is conducted into a treated water tank 8.
