Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a flushing system for a lateral flow inclined plate sedimentation tank. Background Art

[0002] In the water treatment process, after the raw water and the reagent are mixed and enter the sedimentation tank, most of the flocs will settle to the inclined plate, and then slide from the inclined plate to the bottom of the sedimentation tank. However, due to the light weight of the flocs, a certain amount of flocs will remain on the inclined plate. After a period of accumulation, the flocs remaining on the inclined plate will continue to increase, which will not only block the inclined plate, affect the water flow cross-sectional area and affect the design flow rate, causing the turbidity of the outlet water to be unstable, but also increase the dead weight of the inclined plate, causing the inclined plate to exceed the load capacity and collapse during precipitation maintenance. Therefore, it is necessary to regularly flush the deposited flocs on the inclined plate.

[0003] At present, the inclined plate sedimentation tanks in water plants are usually flushed with regular manual high-pressure water, which requires water to be stopped and reduced in each cell. The flushing time is long and the labor intensity of the workers is high, which also has a great impact on the stability of the effluent water quality.

[0004] Therefore, it is very urgent to solve the above technical problems. Utility Model Content
