ã€working principle】
The treated part of the wastewater is circulated into the dissolved gas tank. Under the pressurized air state, the air is supersaturated and dissolved, and then mixed with the raw water to which the flocculating agent is added at the inlet of the air floating pool, and the supersaturated air is released due to the pressure reduction. Microbubbles are formed, which quickly adhere to the suspended matter and lift it to the surface of the flotation machine, thereby forming a sludge floating layer that is easily removed, and the heavier solid matter is deposited at the bottom of the tank and is also removed.
[Scope of application]
It is suitable for purifying sewage with high chroma, low dissolved oxygen and many organic impurities. It is especially effective for sewage purification with low water temperature. This process is suitable for industrial wastewater treatment and production water treatment after printing, dyeing, electroplating, tanning, paper making, chemical, textile, meat processing, oil refining, canned food, etc. It is also suitable for the separation of biological mud film and water in biological treatment. .
ã€Process Features】
1. Under the pressurized condition, the solubility of air is large, and the number of air bubbles used for air supply and floating is large, which can ensure the air floating effect;
2. The dissolved gas is released under sudden decompression, and the bubbles are not only fine, uniform in particle size, large in density, stable in floating, and small in disturbance to liquid, so it is especially suitable for solid-liquid separation of loose flocs and fine particles;
3. The process and equipment are relatively simple, easy to manage and maintain; especially the partial reflux type, the treatment effect is remarkable and stable, and the energy consumption can be greatly saved.
