Description

Technical Field

[0001] The utility model relates to a decanter, in particular to a decanter of a sewage treatment biochemical pool, belonging to the technical field of sewage treatment. Background Art

[0002] The decanter is a device used in the SBR process to remove clarified water regularly. It can automatically rise and fall with the change of water level during the drainage stage, and the clarified water is decanted from the static pool surface, while the scum on the surface is effectively trapped in the reaction pool. Since the SBR process adopts intermittent reaction, water intake, reaction, sedimentation, and drainage are completed in the same pool, and no secondary sedimentation tank and sludge return equipment are required, it has the advantages of small footprint, small investment, high efficiency, and good effluent quality.

[0003] A decanter for a sewage treatment biochemical pool is disclosed in the Chinese patent application publication specification CN215756655U. The device includes a power mechanism, a drainage structure and a filtering structure. The filtering structure includes a filter plate, an adjustment handle, a rotor and a water regulating plate. A water regulating plate is arranged above the filter plate. The water regulating plates are threadedly connected by the adjustment handle. Both ends of the water regulating plate are fixedly connected to the rotor. The device can not only filter the mixed debris in the clarified water through the power mechanism, the drainage structure and the filtering structure, but also adjust the water delivery direction, reduce the water flow speed, and avoid the pool bottom vibration caused by excessive drainage.

[0004] Although the suspended matter in the biochemical pool can be filtered in the implementation scheme of the above patent, it can only be blocked at the top. After long-term use, the debris on the pool surface accumulates more and more, which is easy to block the water inlet and reduce the decanting flow rate. If it is not cleaned in time, the pool surface will be polluted, thereby affecting the water quality of the decanter. Utility Model Content
