When the air flotation equipment is in use, the dissolved air of the multi-phase miscible aerosol dissolving tank also dissolves dissolved air (the air and water are mixed at a certain pressure), and the dissolving water is discharged through the decompressor and is released for processing. In the water. The air dissolved in the water is released from the water, and tiny bubbles of 20-40 μm are formed at this time. The sewage after the dosing reaction enters into the air-floating mixing zone, and the dissolving gas after the release is mixed and contacted. The floc adheres to the microbubbles and then enters the flotation zone.
When the flotation device is in use, the flocs float to the surface to form scum under the effect of buoyancy. After the lower layer of clean water flows to the clear water pool through the water collector, part of the reflux is used as dissolved gas, and the remaining clear water passes through the overflow. Outflow. After the scum on the surface of the flotation tank accumulates to a certain thickness, it will be scraped into the flotation tank and discharged by the scraper. The clear water enters the clear water tank from the lower part through the overflow tank.
For the pollutants in the sewage, this time will be divided into dissolved organic matter and non-soluble matter (ie, SS). Under certain conditions, dissolved organic matter will also be converted into non-solution properties. substance.
One of the methods of sewage treatment is to pay attention to the addition of coagulants and flocculants to convert most of the dissolved organic matter into non-dissolvable substances. Afterwards, all or most of the nonsolvent substances (ie, SS) can also be obtained. Removal is to achieve the purpose of purifying the sewage, but the main method for removing the SS is to use a multiphase miscible floater.
Air flotation equipment is a kind of solid-liquid separation equipment that is often used in the sewage treatment industry. When it is actually used, it can effectively remove suspended solids, grease, and glue substances in the sewage. In this regard, it is actually the same. One of the main types of pre-treatment equipment for wastewater treatment is also capable of effectively removing the frivolous and difficult-to-precipitate effluent from the wastewater in the case of a multi-phase miscible aerated flotation machine.http://www.shallowairfloatation.com
