Abstract

The invention relates to the technical field of water treatment, particularly to an efficient air floatation tank for wastewater treatment. The efficient air floatation tank for wastewater treatment comprises a tank body, a water outlet tank and a reflux pipeline, wherein the water outlet tank comprises a high-water-level tank body and a low-water-level tank body, the tank body is communicated with the high-water-level tank body through an overflow port, the high-water-level tank body is communicated with the low-water-level tank body through an overflow port, and the tank body is also communicated with the high-water-level tank body through the reflux pipeline. According to the invention, the water outlet tank is divided into the high-water-level tank body and the low-water-level tank body, the high-water-level tank body provides required water for the reflux pipeline, and the low-water-level tank body is used for draining water, so that equivalently a water storage space is specially added for a 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 a high-efficiency 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 dissolved air tank cannot be guaranteed, which in turn affects the aeration effect of the release device, 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 a high-efficiency air flotation tank for wastew...
