The wastewater treatment apparatus A includes an upper support member 2 made of a perforated plate at two upper and lower locations on the inner wall surface of a vertical treatment tank 1.
And the lower support member 3 are bridged.
Between them, a microorganism-filled layer 4 filled with a filler carrying aerobic microorganisms is formed. A raw water dispersion layer 6 is formed by laying a large number of spherical bodies 5 having a specific gravity lighter than water on the upper support member 2 in layers.

To purify raw water (effluent). In this way, the raw water (drainage) that has been treated and purified of the organic matter is discharged to an external river or another facility that performs post-processing via the drain pipe 10. The gas generated by the decomposition of the organic matter is exhausted from the exhaust pipe 11 by the exhaust fan 12 together with the air.

Clogging occurs. At this time, the raw water (drain) cannot pass through the raw water dispersion layer 6 and the raw water accumulates on the upper surface of the raw water dispersion layer 6, but floats on the surface of the raw water because the specific gravity of the spherical body 5 is smaller than the raw water (drain). As a result, the spherical body 5
A gap is formed between the raw water and the raw water (drainage) flows through the raw water dispersion layer 6 and flows into the microorganism-filled layer 4. In this way, the clogging that occurs in the raw water dispersion layer 6 is automatically released, and the raw water (drainage) is not prevented from passing through the raw water dispersion layer 6.

The aerobic microorganism-carrying filler, which accumulates therein or alternatively penetrates the microorganism-packed layer 4. When the filler is coated, oxygen is not supplied sufficiently, and the activity of the aerobic microorganisms gradually decreases and eventually dies. Therefore, it is necessary to periodically stop the operation of the wastewater treatment apparatus A to remove insoluble contaminants accumulated inside the treatment tank 1.

In this case, the filler must be replaced with a new aerobic microorganism-carrying material. As in the case described above, such replacement work requires a great deal of labor and work time, and thus has a problem that the stop time of the wastewater treatment device A is prolonged and a problem that maintenance costs are high.
