答：曝气的作用在污水治理工艺中，一般选用罗茨风机或沉水风机，架设管道连接曝气盘，向污水中强制加入空气，使池内污水和空气接触充氧，并搅动液体，加速空气中的氧气向液体中的转移，防止池内悬浮体下沉，加强池内**物与微生物和溶解氧的接触，对污水中**物进行氧化分解，这种向污水中强制增氧的设备称为曝气设备。

　　其作用如下：

　　1,、将空气中的氧转移到混合液中的活性污泥絮体上，以供应微生物呼吸之需

　　2、搅拌，混合是曝气池内的混合液体处在剧烈的混合状态，是活性污泥中的**污染物三者充分接触。同时也起到防止活性污泥在曝气池内沉淀的作用！

以上两点就是污水曝气的作用！

　　Answer: the role of aeration is in the sewage treatment process. Generally, roots blower or submerged blower is selected. Suppose that the pipeline is connected with the aeration disk, and air is forcibly added to the sewage, so that the sewage and air in the pool contact and oxygenate, and stir the liquid, accelerate the transfer of oxygen in the air to the liquid, prevent the suspension in the pool from sinking, strengthen the contact between the organic matter in the pool and microorganisms and dissolved oxygen, and oxidize and decompose the organic matter in the sewage, This kind of equipment for forcibly adding oxygen to sewage is called aeration equipment.

　　Its functions are as follows:

　　1. Transfer the oxygen in the air to the activated sludge flocs in the mixture to supply the needs of microbial respiration

　　2. Mixing and mixing means that the mixed liquid in the aeration tank is in a violent mixing state, and the organic pollutants in the activated sludge are in full contact with the three. At the same time, it can also prevent activated sludge from settling in the aeration tank!

　　The above two points are the function of sewage aeration!
