The inner and outer bead parts 420 and 430 formed therein and a partition wall 440 for dividing the inner space of the main body 410 into a plurality of spaces. In addition, the microorganism carrier 400 can be assembled in multiple stages while forming a ventilation space (S) with the neighbors, the structure for this is as follows.

First, the cylindrical body 410 is formed in a cylindrical shape having a predetermined height and open at both ends, and has a density of 0.92 to 0.96 g / cm 3 so as to flow smoothly inside the oxygen-free tank 300. ) It is preferably composed of synthetic resin.

First, the anoxic tank 300 is filled with microbial carriers 400, and anaerobic microorganisms adhere to the surfaces of the microbial carriers 400 and inhabit. In addition, when the waste water / waste water flows into the aerobic tank 100 through the inlet pipe 110, a part of it is introduced into the anaerobic tank 300 through the inlet (310).

In this state, when the air pump 220 is driven to blow air (oxygen) into the aerobic tank 100 in which the wastewater / wastewater is stored through the air-supply pipe 200, a considerable amount of oxygen is evenly mixed in the wastewater / wastewater. It flows inside the aerobic tank 100. That is, the wastewater introduced into the aerobic tank maintains an appropriate oxygen partial pressure, while contaminant concentrations are uniformly distributed, and organic materials are oxidized and decomposed.

Subsequently, some of the treated water primarily treated in the aerobic tank 100 enter the anaerobic tank 300 through the inlet 310 as described above.

On the other hand, if the waste water / waste water is continuously introduced into the aerobic tank 100 through the inlet 110, the water level in the anaerobic tank 300 also gradually increases.

At this time, the wastewater flowing out through the discharge pipe 320 is purified by the catalytic oxidation method through the microbial carriers 400 through which anaerobic microorganisms are growing. That is, the microbial carriers 400 are located inside the oxygen-free tank 300, and the microorganisms inhabiting the microbial carriers 400 purify the waste water by the catalytic oxidation method. At this time, in the microbial carrier 400 according to the present invention, the surface area is widened due to the inner / outer bead portions 420 and 430 and the partition walls 440, so that the microorganisms easily adhere to the microorganisms. Is done. In particular, while the microbial carriers 400 are located inside the oxygen-free tank 300, the water flow (water flow) is also through the aeration space (S) between the open and open ends of the body 410 and the microbial carriers 400 assembled in multiple stages. The waste water is purified more effectively.

As a result, only the purified wastewater / waste water passing through the microbial carrier 400 in the anaerobic tank 300 exits through the discharge pipe 320.

Of course, in the embodiment of the present invention, although the microbial carriers 400 are located only in the oxygen-free tank 300, the microbial carriers 400 may be disposed in the aerobic tank 100 according to the embodiment.
