The air floatation method means that according to the dissolved gas water caused by the dissolved gas system software, the pressure is released quickly and released into the water, causing a lot of fine bubbles in the water. Suspended solids with a density less than 1 are raised to the surface of the river according to the buoyancy of water, and this is a method of purifying water by solid-liquid separation equipment. The high-efficiency shallow air flotation device is based on the traditional air flotation basic theory, and has successfully applied the basic principles of "shallow basic theory" and "zero speed". According to careful planning, it integrates cohesion, air flotation, The integration of skimming, settling, and scraping mud are high-efficiency machinery and equipment for this sewage purification solution.

    Floating air divided into 4 parts

    (1) Dosing and coagulating part (2) Flowing back water-soluble gas and releasing part (3) Air flotation purified water part (4) Household appliance operating part

    (A) the coagulation part

    The sewage is raised from the air oxidation tank to the air reflection tank. Set one end of the pipe mixer in the water inlet path. That would allow the potion and the sewage to be sufficiently mixed, which would cause the sewage to coalesce. The supply and demand of medicine is balanced by the dosing device.

    (B) the part released back to the water-soluble gas

    The key to the actual effect of tritium air flotation is the actual effect of returning water-soluble gas and releasing it. This air flotation uses high-efficiency environmental protection and energy-saving dissolved gas and released equipment. This machine is based on the technology of Shanghai Jiaotong University. After the air of the air compressor is compressed and resolved, the return water flow charged by the centrifugal pump will be fully mixed and dissolved in the dissolved gas tank to generate dissolved gas water. The pressure of the dissolved gas tank is 2 to 3 kg / cm2.

    (C) air purification water

    According to the sewage of the concrete sprayed into the air flotation tank, the dissolved water in the gas tank is suddenly relieved by the dissolved gas releaser under the water inlet, so that the gas dissolved in the water is released from the pressure to release a lot of micro steam Bubbles, microbubbles encounter suspended solids that have already agglomerated in the wastewater during the entire rise process, and the microbubbles adhere to the suspended solids, causing it to rise rapidly, so that all suspended solids resolved in the wastewater float on top Then they are scraped off and discharged into the silt pond by the scraper at the upper end of the air flotation, and the bottom end of the pond is discharged according to the cold water that is solved.

    (D) Operation part of household appliances:

   The home appliance control box attached to the machine and equipment can be adjusted and installed to achieve no actual operation. The electrical cabinet controls the operation of the dissolved-gas centrifugal water pump, foam scraper, and air compressor.

    1. Under the pressure standard, the solubility of the gas is large, and the total number of bubbles used for air floatation is large, which can achieve the actual effect of air floatation;

     2. The incorporated vapor is released after abruptly alleviating the pressure. The resulting bubbles are not only fine, the particle size distribution is uniform, the flow is large, and the upward adjustment is stable. Liquid separation equipment

    3. The whole process of processing technology and machinery and equipment are very simple, easy to manage and maintain; it is a part of the flow-back type, which has a remarkable and stable solution effect, which can greatly save energy consumption.
