Biochemical oxygen demand, chemical oxygen demand and SS due to various dissolved organic components or insoluble suspensions can be reduced by the digestive activity of bacteria.

The treatment tanks (2, 3, 4) are integrated into three or more stages according to the wastewater treatment system, and are configured or separated into one body (1). Can be. In the treatment tanks 2, 3 and 4, through the two boundary surfaces 10 and 10 ', the central aeration chamber 2a: 3a: 4a as the inlet part and the left and right settling chambers 2b: 3b: as the outlet part are provided. 4b) are distinguished and are connected to each other internally.

At the bottom of the aeration chambers 2a: 3a: 4a, a plurality of air holes 9 are formed at 45-60 degrees, respectively, so that the sediment is not accumulated and the entire surface is aerated. The diffuser 8 which consists of a large number of left and right holes 9 for air diffusers, while the untreated water is introduced into the aeration chamber 2a of the first treatment tank 2 through a predetermined length of pipe (not shown). Air is uniformly blown through) so that the aeration is constant in the aeration chamber 2a during the production.

On the other hand, the aeration chamber (2a: 3a: 4a), as shown in Figure 2 is stirred with the biochip as a treatment medium with the treated water introduced as shown in FIG. 2b: 3b: 4b), and this settling chamber (2b: 3b: 4b) supplies the supernatant water after the sedimentation treatment as treated water to the aeration chamber of the next treatment tank through the treated water channel (5: 6: 7).

That is, the sedimentation chamber 2b of the first treatment tank 2 is the aeration chamber 3a of the second treatment tank 3 and the second treatment tank is the treatment water passage 6 as the treatment water passage 5. The sedimentation chamber 3a of (3) is the aeration chamber 4b of the 3rd treatment tank 4, and the sedimentation chamber 4a of the 3rd treatment tank 4 is the next pair, respectively, with the other process water flow path 7, respectively.
