Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment flocculation sedimentation filtering device. Background Art

[0002] The existing urban sewage mostly adopts biological phosphorus removal process, but it is difficult for the treated sewage to stably meet the Class A standard requirements for total phosphorus discharge. Therefore, it is necessary to further treat the secondary effluent after biological treatment to further reduce the phosphorus content in the water;

[0003] In the deep treatment, the removal of phosphorus mainly adopts the chemical phosphorus removal method, which is to add inorganic metal salt reagents, such as FeCl3, to combine with phosphate to form granular insoluble substances, which are then accumulated through chemical flocculation reaction to form larger flocs, and finally removed by filtration;

[0004] The existing device puts inorganic metal salt reagents into the sewage during sewage flocculation treatment, and filters impurities and flocculants through the filter. However, after the filtration is completed, the impurities and flocculants are above the filter and it is not convenient to clean them. Therefore, a sewage treatment flocculation sedimentation filtration device is proposed. Utility Model Content
