Abstract

The invention relates to a rotational flow shearing bubble aerator comprising an air inlet base, a one-way valve, an air distributor, a reaction outer barrel, a reaction inner barrel and a shearing bubble diffusion disc, wherein the one-way valve is arranged on the air inlet base, one surface of the one-way valve is connected with the air inlet base, and the other surface is connected with the reaction outer barrel; the air distributor is arranged in the one-way valve and the reaction outer barrel, the bottom of the air distributor is connected with the air inlet base, and the upper part is connected with the shearing bubble diffusion disc; the reaction inner barrel is arranged between the periphery of the air distributor and the reaction outer barrel; the bottom of the shearing bubble diffusion disc is provided with a first-stage rotational flow step and a second-stage rotational flow step; and the first-stage rotational flow step and the second-stage rotational flow step are provided with teeth. A broken bubble principle of a macropore (relative to a micropore) slit high-speed injecting air distribution and shearing bubble diffusion combined action is adopted in the invention, thus bubbles with more appropriate size are obtained and distributed more uniformly.

Description

technical field [0001] The present invention relates to aerobic biological treatment of sewage, in particular to a swirling shear bubble aerator for oxygenation of urban sewage treatment and upgrading of sewage plants, various organic industrial wastewater treatment and upgrading, and micro-pollution source water treatment . Background technique [0002] In the sewage aerobic biological treatment project, water treatment workers use aeration method to meet the oxygen content in the metabolic process of aerobic microorganisms. Therefore, aeration equipment becomes the most important component of this treatment method. The quality of the aeration equipment and the quality of its operation directly affect the efficiency of sewage treatment and daily operating costs, and some even affect the success or failure of the entire sewage treatment system. [0003] At present, the aeration equipment used in the domestic blast aeration system mainly includes large and medium bubble aer...
