Embodiment 1
[0023] like figure 1 As shown, a kind of sealed dissolved air flotation machine provided by the present invention comprises air flotation tank, suction pipe 7, suction pump 10, bubble releaser 9, dissolved air system, gas-liquid separation tank 4; Described air flotation tank is Sealed box structure, the air flotation tank is provided with a first partition 5 and a second partition 6, the first partition 5 and the second partition 6 divide the air flotation tank into contact tank 1, scum separation tank 2 and clean water pool 3; the gas-liquid separation pool 4 is a sealed box structure.
[0024] The bottom of the scum separation tank 2 is provided with a clean water pipe 8, which is a tubular structure extending along the length of the scum separation tank 2, and a plurality of small holes are evenly arranged at the bottom of the clean water pipe 8. The clean water pipe 8 One end of it is closed, and the other end passes through the second dividing plate 6 and communicates w...

The invention relates to a sealed dissolved air floatation machine, which consists of an air floatation tank, a suction pipe, a suction pump, a bubble releaser, an air dissolving system and a gas-liquid separation tank. The air floatation tank is a sealed box structure, and the air floatation tank is internally equipped with a contact pool, a separation pool, a clear water pool and a scum pool. The gas-liquid separation tank is a sealed box structure. The air dissolving system includes a reflux pump, a dissolved air pot and an air compressor, one end of the reflux pump is connected to the clear water pool, and the other end is connected to a water inlet of the dissolved air pot, a water outlet of the dissolved air pot is communicated with the bubble releaser, and an air inlet of dissolved air pot is connected to the air compressor. The suction pipe is mounted above the scum separation pool liquid level, the suction pump sucks the scum, stink and poisonous gas in the scum separation pool into the gas-liquid separation tank through the suction pipe, the scum and gas are separated in the gas-liquid separation tank, then the gas enters the dissolved air pot and mixes with sewage in the dissolved air pot to form air dissolved water again, and the air dissolved water enters the contact pool, stink or poisonous gas is not discharged into the air directly, no secondary pollution is generated, and the gas loss is little, and is close to zero.
Description
technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a dissolved air flotation machine. Background technique [0002] At present, the pollution brought by industrialization has greatly deteriorated the human living environment. All kinds of water sources are polluted to some extent. People use the air flotation process to remove suspended solids, colloids, grease and other impurities in sewage in the process sections such as tap water pretreatment and municipal sewage standard discharge. [0003] Dissolved air flotation technology is a solid-liquid separation technology, which has the characteristics of high processing efficiency, short start-up time and small footprint, and is widely used in the field of water treatment. The air flotation process is a method of relying on the formation of tiny bubbles in the water to carry the flocs up to the liquid surface to purify the water. The condition is that the bubbles attached...
