And a fluidized bed 20 and a stationary bed 21 are formed, and a diffuser 24,
In addition, an air lift pump 26 is provided below the stationary layer 21 so as to drain the cleaning drainage when the stationary layer 21 is washed. The fluidized bed 20 constantly discharges air from an air diffuser 24 provided below the fluidized bed 20 to perform aerobic treatment except when the stationary bed 21 described below is washed.

駆動源に空気を吐出させている。The stationary bed 21 carries out aerobic treatment by carrying over dissolved oxygen to the water transferred from the fluidized bed 20, and makes the filled carrier (filter medium) stationary to efficiently filter and remove SS. Let it. Therefore, the stationary layer 21
Washing is performed because the SS is gradually clogged by the trapped SS. In this washing, the dispersion provided at the lower portion of the stationary layer 21 in order to allow the carrier to flow and separate the trapped SS. Air is discharged from the trachea 25 for bubbling. In the cleaning of the stationary layer 21, the separated SS is extracted from the lower portion of the stationary layer 21 as cleaning drainage. An air lift pump 26 is used for the extraction, and air is discharged to a driving source of the air lift pump 26. Let me.

される。The cleaning of the stationary layer 21 is automatically performed according to a command from a timer or the like, and is performed periodically, for example, at a time when the inflow of sewage is small, for example, at midnight. Also,
The cleaning of the stationary layer 21 is usually performed once a day for about 1 to 30 minutes, but the cleaning frequency and the cleaning time are not necessarily limited to the above ranges. Note that the stationary layer 21 can be washed at any time by manual operation. On the other hand, while the stationary bed 21 is being cleaned, the supply of air to the air diffuser 24 below the fluidized bed 20 is stopped.

Furthermore, blowers (11, 1
The air from 2) is used, and the air is supplied to a part that discharges continuously (including a substantially continuous state) and a part that discharges for a short time (herein referred to as intermittent).
Therefore, in the septic tank 1 used in the present invention, the air supply destination in the septic tank 1 is divided into a continuous system and an intermittent system, and the air introduction port 9 provided in the septic tank 1 is connected to the continuous system pipe. Further, the air inlet 10 is connected to the intermittent piping so that the number of air inlets to the septic tank 1 from the outside is reduced as much as possible. This has the effect of simplifying the connection of the piping and preventing erroneous piping. In addition, the air inlet provided in the septic tank 1 is not limited to the two air inlets 9 and 10 described above, and two or more air inlets are provided by combining the continuous and intermittent air inlets.

From individually connected pipes, the pipes pass through the junction pipe 13 to branch pipes 14 and 15. An air switching valve 16 is provided in the branch pipe 14 and / or the branch pipe 15. When the air switching valve 16 is provided in the branch pipes 14 and 15, the operation state of each air switching valve 16 is reversed. For example, a two-way valve is used for the air switching valve 16 and the air switching valve provided in the branch pipe 14 is used. When the valve 16 is opened and the air switching valve 16 provided in the branch pipe 15 is closed, air can be supplied to the continuous air inlet 9. When supplying air to the intermittent air inlet 10, the air switching valve 16 provided in the branch pipe 14 is closed, and the air switching valve 16 provided in the branch pipe 15 is opened.

The pressure loss applied to the air inlet 9 series connected to 4 is made smaller, and a two-way valve is used as the air switching valve 16,
The two-way valve is closed. Thus, the air is supplied to the continuous air inlet 9 in a normal state. When supplying air to the intermittent air inlet 10, when the two-way valve of the air switching valve 16 is opened, air is supplied to the branch pipe 15 having a small pressure loss, while the branch pipe 14 having a large pressure loss is supplied.
