Abstract

The invention discloses rotational-flow static-state mixed aeration apparatus used for sewage treatment aeration. The apparatus comprises a cylindrical outer shell, an air inlet pipe joint, a one-wayvalve, a square air inlet flow guide pipe, an air inlet volute fluid director, a rotating air deflector, a spiral groove-typed bubble cutting device and a top fixing ring, after compressed air tangentially enters the air inlet volute fluid director through the square air inlet flow guide pipe, a rotational flow is produced, the rotation of the rotational flow is strengthened through the rotating air deflector in the rotational-flow rising process, the strengthened rotational flow collides with the spiral groove-typed bubble cutting device to form fine bubbles and generate vortexes, aeration oxygen supply and stirring are performed on sewage in a tank, so that the fine bubbles and the sewage are fully contacted, the oxygen utilization rate is effectively improved, and the apparatus has theadvantages of high oxygen dissolving efficiency, small resistance loss, strong stirring force, no clogging, intermittent operation, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment aeration equipment, in particular to a cyclone static mixing aeration device. Background technique [0002] Aerobic treatment is a process unit commonly used in sewage treatment technology. The activated sludge microorganisms in the sewage of the aerobic pool degrade organic pollutants under the condition of air supply and oxygenation, so as to achieve the purpose of removing various organic pollutants. [0003] The aerator is an essential equipment for aeration and oxygenation in the aerobic process of sewage treatment. The blower generates pressure air, which is transported to the aerator through pipelines, and the oxygen is evenly distributed in the sewage to provide the oxygen source required by microorganisms. When the air bubbles formed by the aerator come into contact with the sewage, the oxygen in the air bubbles is dissolved in the water. The indicator for evaluating the effect ...
