Problems solved by technology

However, when the existing air flotation tank is running to treat wastewater, the bubbles attached to the suspended matter with a slightly larger specific gravity will burst during the rising process, forming secondary sedimentation, polluting the water quality in the separation area, thus restricting the water purification efficiency of the air flotation device play

Abstract

The invention discloses a novel air floatation tank. The novel air floatation tank comprises a reaction zone, an air floatation separation zone and a pressure dissolved air floatation device, whereinthe reaction zone is externally connected with a sewage inlet pipe, an air floatation contact zone is arranged between the reaction zone and the air floatation separation zone, and a water passing pipe communicated with the reaction zone and the air floatation contact zone is arranged between the reaction zone and the air floatation contact zone; a vertically arranged central pipe is arranged in the air floatation contact area, and the top end of the central pipe is connected with the water outlet end of the water passing pipe; a slag scraping plate is arranged above the air floatation separation zone and the air floatation contact zone, a filter layer is arranged at the inner side of the air floatation separation zone, and the filter layer is horizontally arranged to divide the air floatation separation zone into a to-be-purified zone located above the filter layer and a clear water zone located below the filter layer; and the pressure dissolved air flotation device comprises a pressure dissolved air tank connected with the clear water zone through a pipeline, and a dissolved air water releaser installed in the air flotation contact zone and connected with the pressure dissolved air tank through a pipeline. The novel air floatation tank can effectively improve the pollutant removal efficiency and reduce the resource waste and the production cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel air flotation tank. Background technique [0002] The air flotation treatment technology of water and wastewater is a water treatment technology that uses highly dispersed micro-bubbles as a carrier to adhere to suspended particles in the water, so that they can be separated and removed with the bubbles rising to the water surface. However, when the existing air flotation tank is running to treat wastewater, the bubbles attached to the suspended matter with a slightly larger specific gravity will burst during the rising process, forming secondary sedimentation, polluting the water quality in the separation area, thus restricting the water purification efficiency of the air flotation device play. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a novel air flotation...
