Description

Technical Field

[0001] The utility model relates to the technical field of sludge thickening, in particular to a sludge thickening and sludge discharging device. Background Technique

[0002] The sludge generated in the wastewater treatment process has a very high water content, so the volume of the sludge is relatively large, which causes difficulties in the treatment, utilization and transportation of the sludge. Sludge thickening is to reduce the water content and volume of the sludge by sludge thickening, so as to reduce the subsequent treatment cost. The commonly used methods for sludge thickening are gravity thickening method, air flotation thickening method and centrifugal thickening. At present, in the market, small-volume sludge thickening usually adopts a gravity sludge thickening tank.

[0003] For example, the high-efficiency sludge thickening tank with the publication number CN108147642A. This sludge thickening tank has a long residence time through gravity sedimentation and has no chemical conditioning function, which prolongs the sludge thickening time. Moreover, for some sludge thickening and sludge discharging devices, when adding chemicals, the chemicals are simply poured into the sludge thickening tank, making it impossible for the chemicals to fully contact the sludge. Therefore, a sludge thickening and sludge discharging device is proposed. Content of the Utility Model
