In order to make environmental protection work more smoothly, shallow air flotation is currently used in sewage treatment. The system can generate relatively large centrifugal force through high-frequency rotation speed during operation, so that the concentration of dissolved soda water can reach the concentration standard in a few seconds, and the speed of sewage treatment is very fast.

First, the sewage flows into the sump through the discharge channel. After flowing into the pool, the sewage can be balanced, and then the lift pump will bring the sewage to the shallow air flotation tank. When the sewage enters the shallow air flotation tank, the force of the system can make the sewage into a static state, so that the water flow speed can be controlled.

In the process of systematic treatment, some pollutants in the sewage will be slowly separated, and these pollutants will also float on the water surface, and then they can be picked up by special equipment, and the clean water in the lower layer can be transported to the clear water tank for circulation use.

As a relatively efficient and energy-saving sewage treatment equipment, shallow air flotation plays a great role in wood industry wastewater. The discharge of the water in the shallow air flotation is carried out after the solid-liquid separation, and the scum is isolated and removed instantaneously. High solid rate.

The water distribution device is a rotary type. With the rotation of the water distribution device, the bubbles that have been fully and evenly mixed with the sewage can fill the entire purification tank very uniformly, and there is no air floating dead area or uneven bubble area, thus greatly improving Purification efficiency. With a new type of releaser, not only the pressure drop is steep, but also the energy dissipation is uniform, the micro-bubble release environment is quiet and without turbulence, the diameter of the released micro-bubble is very small and uniform, the removal rate of suspended COD is significantly improved, and the dosage can be greatly reduced. quantity.
