This equipment directly pours into the sewage with "microbubble" and need not to dissolve gas in advance, disperses "microbubble" in sewage on average through the impeller that looses, so whole operation process can not take place the blocking phenomenon. A large amount of 'micro bubbles' generated by the equipment are adhered to solid or liquid particles with the density close to that of water in the wastewater, so that the overall density of the particles is less than that of the water, the particles can rise to the water surface by means of buoyancy, solid and liquid are separated, and the sewage treatment effect is achieved.
The working principle is as follows: sewage enters an oil separation tank 3 through a fine grid 7, floating oil is removed, then the sewage enters a cavitation air flotation tank 5 through a water collecting tank, pollutants in the sewage are divided into soluble organic matters and non-soluble matters (namely SS), the soluble organic matters can be converted into the non-soluble matters under certain conditions, a coagulant and a flocculant are added to the front section of the air flotation tank 5 to convert most of the soluble organic matters into the non-soluble matters, a large number of micro bubbles are generated in the middle section, particles of the non-soluble matters are adhered, the overall density of the particles is smaller than that of the water, the particles can rise to the water surface by virtue of buoyancy, and the particles are hung out and collected by a slag scraper 11, so that all or most of the non-soluble matters (namely SS) are removed to achieve the purpose of purifying the sewage, and the equipment is used for treating the urban sewage and the industrial sewage without auxiliary equipment such as a pressure dissolving tank, an air compressor, a circulating pump and the like. The equipment can remove grease, jelly, solid suspended matters, COD and BOD in sewage, and can greatly reduce the biochemical secondary treatment if waste paper is used as raw material, and the waste water generated in the processes of deinking, bleaching and the like can be discharged up to standard or recycled on the scale of equipment without the biochemical secondary treatment, even can directly discharge up to standard without biochemical treatment process, thereby greatly reducing the total investment cost, and the equipment adopts a multi-element aeration head, the number of aeration machines is determined according to the difference of the treated water amount, and the power of each aeration machine is only 2.2kW; the mud scraping plate and the sludge screw propeller are driven by the same motor, and the power is 0.37kW-1.1kW. The cavitation air flotation equipment consumes extremely little power which is only equal to 1/8-1/10 of that of the traditional dissolved air flotation method, has extremely little maintenance and manual operation, does not need workers to keep during normal operation, and automatically and continuously removes the solid sludge from the wastewater in contrast to the gravity settling tank and the separation tank of the traditional grease collector. The sludge is removed and stored in a concentration mode, and the floating sludge collected by the equipment has low water content, so the operating cost of sludge treatment is also reduced; the performance is also very superior, and the removal rate of petroleum and Suspended Solids (SS) is over 80 percent. The removal rate of BOD and COD can reach more than 60 percent. While the dissolved air floatation system can only achieve about 35 percent of removal rate of BOD and COD. The oxidation of sulfide can be promoted, and the sulfur content in the sewage is reduced; finally, the treatment process of the equipment to the waste water is an aerobic process, and the problem of odor in the sludge is effectively solved.
