Description

Technical Field

[0001] The utility model relates to the technical field of air flotation and sedimentation integrated machines, in particular to an integrated coagulation and sedimentation air flotation integrated machine. Background Art

[0002] The flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by the dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby achieving solid-liquid separation. In addition, the coagulation and sedimentation equipment, under the action of coagulants, causes the colloids and fine suspended matter in the wastewater to condense into flocs, which are then separated and removed.

[0003] For example, a Chinese utility model patent (CN218290504U) discloses an integrated coagulation sedimentation flotation machine, which records: "The utility model starts a servo motor through the slag cleaning mechanism, drives the transmission wheel to rotate, thereby transmitting the transmission belt and rotating the slag cleaning plate. The slag cleaning plate in contact with the water surface pushes the slag to the inner side of the collection box. Then, when the slag cleaning plate rotates upward, it contacts the cleaning bar, thereby cleaning the remaining slag on the surface of the slag cleaning plate to prevent excessive slag from sticking to the surface of the slag cleaning plate." It also records: "In the prior art, the two are usually combined into an air flotation sedimentation machine to improve the treatment efficiency and quality of wastewater. However, when the slag cleaning equipment of the air flotation sedimentation machine is actually used, some slag will adhere to the slag cleaning plate in the process of pushing the floccules on the water surface to the collection box. If it is not cleaned in time, the slag cleaning efficiency will be reduced." Technical problems.

[0004] In summary, the device still has the following technical problems: flocculants need to be added to the sewage before flocculation, and then the sewage and the flocculants are quickly mixed by stirring. However, the current sewage treatment often encounters the problem of insufficient mixing of flocculants and sewage, which results in the treated sewage still failing to meet the discharge standards. For this reason, it is necessary to propose an integrated coagulation, sedimentation and flotation machine to provide a new technical solution to solve the technical problems mentioned in the above patents.
