Abstract

The invention relates to the technical field of water treatment, particularly to an air floatation tank for wastewater treatment. The wastewater treatment air floatation tank comprises a tank body, a water outlet tank, a reflux pipeline and a water outlet elbow pipe, wherein the tank body is communicated with the water outlet tank through the reflux pipeline, the outlet end of the water outlet bent pipe is communicated with the water outlet of the water outlet tank, the inlet end of the reflux pipeline is communicated with the water outlet tank, and the setting height of the inlet end of the reflux pipeline is lower than that of the inlet end of the water outlet bent pipe. According to the invention, the arrangement height of the inlet end of the reflux pipeline is lower than the arrangement height of the inlet end of the water outlet bent pipe, so that water in the water outlet tank cannot be completely discharged, equivalently, a water storage space is specially added for the water return pipeline, and the aeration effect of the releaser is prevented from being influenced by insufficient water.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an air flotation tank for wastewater treatment. Background technique [0002] At present, the incoming water of the conventional wastewater treatment air flotation tank device is aerated by the releaser, and the outlet pool is directly connected to the water outlet. However, part of the water in the outlet pool needs to be returned to the pressure dissolved air tank through the dissolved air pump. Due to excessive drainage in the outlet pool, etc., During the operation process, the required water volume of the pressure dissolving tank cannot be guaranteed, which affects the normal operation of the pressure dissolving tank, resulting in poor aeration effect of the releaser, and seriously affects the effluent water quality index of wastewater treatment during production. Contents of the invention [0003] The first object of the present invention is to provide an air flot...
