[0003] In the prior art, an air-dissolving tank is used to mix gas and liquid. When the gas-liquid mixture moves upward from the bottom of the air flotation tank, the volume of the bubbles will be different, and there will be larger bubbles floating from the bottom of the pool, which will cause the gas to not cover the gas evenly. The cross section of the floating pool affects the air flotation effect, and the turbine is used to cut the large air bubbles into small air bubbles twice. At this time, the motor consumes a lot of energy when working in the water, which increases the cost of wastewater treatment.

The invention provides an air flotation tank for waste water treatment. The air flotation tank for wastewater treatment includes a treatment tank; a stirring mechanism; a water inlet mechanism; an air injection mechanism, and the air injection mechanism includes a nozzle pipe, a baffle plate, a return pipe, a dissolved air tank, an air injection fan blade and a first nozzle; a driving mechanism; a cutting mechanism , the cutting mechanism includes a second nozzle, a connecting ball, a fixed rod, a second turbine, a through hole, a fourth gear and a rubber pad; the fourth gear is fixedly connected to the fixed rod, and the side wall of the fixed rod is installed For the connection ball, the rubber pad is installed inside the connection ball, and the bottom end of the connection ball is inclined and equidistant to install the second spray head, and the second spray head is in contact with the rubber pad whose side wall is arc-shaped ; The bottom end of the fixed rod is equipped with the second worm wheel in the shape of a truncated cone, and the side wall of the second worm wheel is evenly provided with the through holes; the impurity removal mechanism. The air flotation tank for waste water treatment provided by the invention has the advantages of saving energy and evenly distributing air bubbles in the air flotation tank.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an air flotation tank for wastewater treatment. Background technique [0002] Air flotation is that the dissolved air system produces a large number of fine bubbles in the water, so that the air attaches to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state of density lower than that of water, and uses the principle of buoyancy to make it float on the water surface, so as to achieve solid- Liquid separation water treatment equipment. Air flotation is divided into super-efficient shallow air flotation, vortex concave air flotation, and advection air flotation. It is currently used in water supply, industrial wastewater and urban sewage treatment. The advantage of air flotation is that its solid-liquid separation equipment has the characteristics of less investment, small footprint, high degree of automation, and convenient ope...
