Design of Aeration Tank in Sewage Treatment Plant

In the equipment of urban sewage treatment plant, aeration tank, as the main link of activated sludge, is the largest energy consumption in the process of urban sewage treatment, and it is also the most obvious link of energy efficiency saving in sewage treatment. Therefore, in the process of urban sewage design, we need to start from the following aspects:

Reasonable selection of aeration equipment
There are two main types of aeration systems in urban sewage treatment plants: blast aeration and mechanical aeration. When selecting aeration equipment, scientific choices must be made according to the sewage treatment process, the scale of sewage to be treated, and the condition of sewage. At present, in the process of urban sewage treatment, the most used micro-porous aeration plate is to pay attention to the regular discharge of condensed water in the process of aeration design to avoid the increase of air line resistance caused by water accumulation in the air line.
