Problems solved by technology

[0002] Sewage usually contains a large amount of impurities and oil. At present, the common electrolytic air flotation sewage treatment method uses insoluble anodes and cathodes to directly electrolyze wastewater, and the tiny bubbles of hydrogen and oxygen generated by electrolysis will intercept and float the flocculated suspended matter to the water surface to achieve For the purpose of solid-liquid separation, although this method has a good treatment effect, there are problems of electrolysis energy consumption and electrode plate loss, and high operating costs.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a sewage air flotation treatment device. Background technique [0002] Sewage usually contains a large amount of impurities and oil. At present, the common electrolytic air flotation sewage treatment method uses insoluble anodes and cathodes to directly electrolyze wastewater, and the tiny bubbles of hydrogen and oxygen generated by electrolysis will intercept and float the flocculated suspended matter to the water surface to achieve For the purpose of solid-liquid separation, although this method has a good treatment effect, it has the problems of high electrolysis energy consumption and electrode plate loss, and high operating costs. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a sewage air flotation treatment device with simple structure, low energy consumption, low ope...
