The air outflow valve 34 is opened to release the air in the lower chamber B to the atmosphere, and the drain siphon destruction valve 20 is opened.
When the drain siphon valve 30 is opened, the water in the upper chamber A in the drain siphon vacuum tank 26 drops, and the water level difference in the lower chamber B increases, as shown in FIG.
When the water in the upper chamber A falls, the air in the upper part of the drain siphon 18 is guided into the upper chamber A of the drain siphon vacuum tank 26, and the water level in the drain siphon 18 rises. A siphon begins to form.

The water in the filtration basin is discharged to the drain 17,
When the water level falls below the drain gutter 6, due to the difference in water level with the water level in the filtrate chamber 8, the filtrate flows through the communication port 9, passes through the water collection chamber 5, backwashes the filter media layer 4, and the cleaning wastewater flows into the drain gutter 6.
Flows from drain culvert 17 by drainage siphon 18.
is discharged. After backwashing the filter layer 4 in this manner, the drain siphon valve 30 is closed and the drain siphon destruction valve 20 is opened to destroy the siphon action of the drain siphon, and the backwash process is completed.
