Fine bubble membrane diffuser with rocker arm is widely used in the first-class biochemical system with heavy production load and bad sewage quality because of its high utilization rate of oxygen and easy maintenance; fixed dynamic aerator is generally used in production because of its low utilization rate of oxygen but long-term maintenance, difficult maintenance but long service life. Two grade biochemical system with lower load and better sewage quality.

There are many kinds of aerators. After continuous renewal and development, their structure and performance are changing with each passing day. This paper introduces only a few of them, and the discussion is only based on the situation of a limited number of sewage treatment plants in the region. Some views have great one-sidedness and limitations. In fact, the selection of aerator should be based on the following factors:

1. The air diffusion device should have higher oxygen utilization and power efficiency, and has better energy saving effect.

2. It is not easy to jam, and it is easy to eliminate failures, so that it is easy to maintain and manage.

3. The structure is simple and easy to install, and the cost of the project and the cost of the device itself are relatively low.

In addition, the quality of sewage, regional conditions, aeration tank type and water depth should also be considered.
