Title:
流入水ゲートを有する廃水処理タンクおよび外方に広がる部分を有する予備反応帯域部
Document Type and Number:
Japanese Patent JP4435421
Kind Code:
B2
Abstract:
A wastewater treatment tank with influent gates (24) and pre-react zone with an outwardly flared lower portion. Influent passes over influent gates (24), which introduce turbulence, causing aeration, and reducing flow velocity. As influent flows out of the influent gate housing (20), flow velocity is further reduced by contact with the surface of the wastewater in the basin and influent flow is directed laterally by an influent gate bottom (30). A pre-react zone director (34) spaced apart from the bottom (42) of the basin encloses the influent gate housing (20) and utilizes an outwardly flared lower portion, or flap (38), to further reduce flow velocity and enhance laminar flow. This results in minimal disturbance of settled sludge blanket, allowing it to act as a natural biological filter, which in turn results in a superior supernatant.
