Abstract

The invention discloses a rotary-type aeration apparatus and an integrated aeration method by mechanical and air compression. The rotary-type aeration apparatus comprises aeration elements, a rotation support, an aeration tank body and a driving device, the driving equipment is connected with a center revolving shaft of the rotation support in a driving mode, the rotation support is erected on the aeration tank body, and the aeration elements are uniformly distributed on a connection end of the rotation support. The rotary-type aeration apparatus and the method have the advantages of high economic performance, efficient and stable operation, simple structure, and convenient operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of aeration for sewage treatment, and is especially suitable for domestic sewage treatment in rural areas and small towns and aeration of industrial wastewater. Background technique [0002] As an important process link of the sewage aerobic biochemical treatment system, aeration is to aerate the reactor with oxygen to ensure the dissolved oxygen required for microbial biochemical action, and to maintain the microorganisms, substrates, and dissolved oxygen in the reactor, that is, The full mixing of mud, water and air provides favorable biochemical reaction conditions for microorganisms to degrade organic matter. At the same time, aeration is also the process link with the highest operating cost in the sewage aerobic biochemical treatment system. The power consumption of aeration and oxygenation generally accounts for 60% to 70% of the total power consumption. Therefore, the aeration device with low energy c...
