Abstract
In this infiltration intake system, a structural body integrally includes a waster discharge direction control portion controlling a discharge direction for wastewater discharged from a filter toward a raw water side at a backwash time with a backwash mechanism portion in a prescribed wastewater discharge direction.
Claims6
An infiltration intake system comprising:
- a structural body, set on a water bottom surface of raw water, including a filter storage portion;
- a filter stored in the filter storage portion;
- a water guide portion for guiding treated water passing through the filter toward the side of a treatment equipment;
- and
- a backwash mechanism portion for washing the filter by refluxing water or air from a treated water side of the filter toward a raw water side, wherein
- the structural body integrally includes a wastewater discharge direction control portion for controlling a discharge direction for wastewater discharged from the filter toward the raw water side to a prescribed wastewater discharge direction at a backwash time with the backwash mechanism portion, and
- wherein the wastewater discharged from the filter is discharged upwardly and the wastewater discharge direction control portion includes a guide portion for guiding wastewater discharged upwardly from the filter to discharge the wastewater sidewise from the structural body as the prescribed wastewater discharge direction at the backwash time.
