The invention provides an ultramicro bubble generating device as well as a water purification system and method. The ultramicro bubble generating device comprises a high pressure air supplying machine, a jet device, a high pressure water pump and an air water mixer, wherein the high pressure air supplying machine is connected with the air water mixer; the high pressure water pump is connected with the jet device, and the high pressure water pump is used for generating a high pressure water body and feeding the high pressure water body into the jet device; and the air water mixer is used for enabling high pressure gas and vaporific water drops to contact so as to achieve over-saturation solvation, thus forming an over-saturation air-water salvation solution. The ultramicro bubble generating device as well as the water purification system and method provided by the invention have the beneficial effects that the air-water salvation efficiency and rate are remarkably improved through changing a high pressure water state by the jet device, gas solvation volume is also increased, the volume of the air water mixer is greatly reduced, and although the jet device needs energy dissipation, the unit energy consumption of gas solvation is reduced as the gas solvation amount is greatly improved.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to an ultramicro bubble generating device, a water purification system and a method. Background technique [0002] Water environment treatment is the weakness of my country's environmental protection. For example, nearly 30 billion yuan has been invested in the treatment of Dianchi Lake, but the quality of water environment has not improved. [0003] With the advancement of science and technology, the water treatment technology using microbubbles to purify water has developed from the laboratory stage to the practical application stage. At present, there are ultra-micro bubble water treatment technology, micro-nano bubble generation technology and other technologies commonly used in China. However, from a comprehensive point of view, this kind of technology has not yet matured, mainly because a large number of ultra-micro bubbles cannot be generated stably and uniformly. As for the ...
