Abstract

PURPOSE: To treat polluted water automatically and continuously by the procedure in which activated sludge is moved circularly and high-concentration oxygen is supplied to the confluence with polluted water.
CONSTITUTION: Polluted water is flowed from the polluted water supply port 17 to the lower part of the aeration tank 8 to combine with circulating sludge at the same place and also the mixed gas of high-concentration oxygen from the high-concentration oxygen source 18 and recover gas from the water surface of the aeration tank 8 is supplied through the blower 23 and the gas bubbler 21. The polluted water reaches the upper part of the aeration tank 8 while being mixed with aerated activated sludge and introduced to the bottom of the inside tank 5 of the reaction separating tank 1 through the mixed liquid inlet pipe 14, and then the sludge grows by taking up pollutants present in polluted water, goes up the inside tank 5, and then forms a sludge layer on the upper part. Treated water is filtered through the sludge layer as a filter and then discharged from the upper end of the reaction separating tank 1 to the treated water discharge drain 28. The sludge layer in the inside tank 5 gradually moves up the sludge collecting tank 6, then flows down and gradually sedimented, and lastly sent to the lower part of the aeration tank 8 again. In this way, polluted water is treated by circulating sludge.
