WASTE WATER TREATMENT DEVICE USING MICROBE CARRIER

摘要

PURPOSE:To provide a waste water treatment device using microbe carriers in a precipitation tank to be separated from treated water without the fear of clogging. CONSTITUTION:A separation plate 6 for circulating microbe carriers 7 along the water flow in an aeration tank 1 is installed with a clearance for treated water inflow formed at its lower end in the vicinity of an outlet of the aeration tank 1 in which microbe carriers 7 are floated. The microbe carriers 7 and floating sludge are carried on the water flow along the separation plate 6 and circulated in the aeration tank 1, and only treated water separated from the carriers flowing into the clearance formed between the separation plate 6 and the side face of the aeration tank 1 is transferred from the clearance to the precipitation tank.
