Then, a signal is transmitted from the control device 31 to the second valve 26, the second valve 26 is opened, and the first storage tank 1 is opened.
The wastewater 11 stored in No. 2 falls in the first pipeline 23 and is discharged into the column 17 due to the height difference between the first storage tank 12 and the column 17. The wastewater 11 is filtered while descending in the filter medium 18 and, as a result, becomes treated water from which specific contaminants have been removed, but since the first valve 25 is still open, the treated water is discharged from the drain port 21. Is discharged to a river or the like through the first valve 25 and the drainage pipe 22. This is the wastewater treatment process.

Then, from the control device 31, the valves 25, 2
A signal is transmitted to 6, 27 and the first valve 25 and the second valve 2
When 6 and 6 are closed, the third valve 27 is opened, and the timer built in the control device 31 is turned on. Then, while the discharge of the treated water from the drain port 21 and the inflow of the waste water to the column 17 are stopped, the fresh water 13 stored in the second storage tank 14 is stored in the second storage tank 14 and the column 17. It drops in the second pipe line 24 due to the height difference and is jetted from the drain port 21 into the column 17 via the third valve 27. Along with this, the water level in the column 17 gradually rises, but this water overflows from the drain port 19 and the drain pipe 2
It is discharged to rivers after passing 0.

To be closed. As a result, the water level in the column 17 is gradually lowered, and the filter medium 18 is settled downward in the column 17. Here, the specific gravity of the filter medium 18 is A as described above.
Since <B <C <D, the filter medium 18 is again held in the column 17 in the order of symbols A to D from above as shown in FIG. This is the drainage process. That is, the initial state of FIG. 3 indicates the final stage of the drainage stroke.

Since both the waste water 11 and the fresh water 13 passing through the column 17 are stored in the storage tanks 12 and 14 installed above the column 17, the waste water 11 and the fresh water 13 are both valve 26. , 27 are simply opened, and due to the height difference between the storage tanks 12, 14 and the column 17, they are automatically introduced into the column 17. Therefore, it is not necessary to use power such as a pump for pumping the waste water 11 or the fresh water 13.
