Title:
WATER TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/213305
Kind Code:
A1
Abstract:
The present invention provides a water treatment device 1, equipped with a stirring tank 10 containing water W2 being treated, and a settling chamber 20. The settling chamber 20 has at least a water-being-treated channeling part 21 channeling the water W2 being treated, and a treated water flowout part 22 through which treated water W3 flows out at a position higher than the water-being-treated channeling part 21. The settling chamber 20 is partitioned from the outside under the water surface of the water W2 being treated in the stirring tank 10, and causes solids such as sludge to settle. In the water treatment device 1, inflow water W1 flows into either the stirring tank 10 or the settling chamber 20, the treated water W3 flows out from the treated water flowout part 22 to the exterior of the stirring tank, and the water W2 being treated in the stirring tank 10 circulates on the outside of the settling chamber 20 in a vertical cross-section passing through the settling chamber 20.
