Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a water decanter for efficient filtration in an SBR tank. Background Art

[0002] The water decanter can accurately discharge clarified water from the upper layer of the static water surface without disturbing the sediment, which is crucial for maintaining the effluent quality. To ensure the efficient operation of the SBR process and meet the requirements of high water volume and water quality changes, the water decanter has the advantages of small floor area, low investment, and simple operation. However, when the existing water decanter is in use, the interception of debris in the sewage only relies on the slag-blocking floating cylinder at the front end of the water decanting tank. When the water surface is relatively calm, the floating cylinder can only block the larger debris in front, but the smaller debris enters the filter opening through the slag-blocking floating cylinder under the action of the water flow. At the same time, when it is not calm, the larger debris will follow the water wave through the floating cylinder into the filter opening. The floating substances and sediments in the influent may cause the blockage of the filter opening of the water decanter. The debris at the filter opening cannot be cleaned in time, resulting in poor effluent quality and unqualified treated water being discharged, thereby polluting the receiving water body and failing to achieve the expected treatment effect. For this reason, we propose a water decanter for efficient filtration in an SBR tank to solve the above problems. Summary of the Utility Model

[0003] The utility model provides a water decanter for efficient filtration in an SBR tank, which solves the problems that the floating substances and sediments in the water may cause the blockage of the filter opening of the water decanter, the debris at the filter opening cannot be cleaned in time, resulting in poor effluent quality, unqualified treated water being discharged, and the failure to achieve the expected treatment effect.
