Impurities are separated by precipitation in this wastewater receiving tank A, and then the raw water is sent to the first treatment tank B1 by the raw water pump 4. An aerator 5 is installed at the bottom of each of the processing tanks B1 and B2, and air is sent from a blower 6. First treatment tank B1
An overflow weir 7 is provided on the wall between the first treatment tank B1 and the second treatment tank B2, and the treated water from the first treatment tank B1 flows over the overflow weir 7 into the second treatment tank B2. In the case of parallel processing, the circulation pump 8 circulates the processing liquid in the second processing tank B2 to the first processing tank B1. In addition, each processing tank B1, B
The amount of inflow to 2 will vary depending on the concentration of the inflowing sewage, but it should be approximately 1/3 or less of the tank capacity and the product of the dilute concentration and water amount within the BOD volumetric load.
