摘要
在污水处理工程中采用活性污泥处理工艺极为普遍,其中曝气设备必不可少的关键设备,目前我国大中小型的污水处理采用的曝气设备一般有:鼓风机+曝气盘(底曝)系统、转刷/转碟系统、表曝机、潜水推流曝气机等,通常选用曝气设备的原则是:根据进水、出水水质,水量,运行费用,使用寿命,维护费用,一次性投资,负面影响及节能环保等方面综合考虑选用。
In sewage treatment works,activated sludge treatment process was very common and aeration equipments were essential and critical equipments.Aeration equipment of all sizes presently used by sewage treatment were aeration blower plate(bottom exposure) system,brush/rotating disk systems,aerators,submersible propeller flow aerators.Usually,aeration equipment selecting principles were in-water and out-water quality,water quantity,operating costs,service life,maintenance costs,one-time investment,and the negative impact of energy-saving and environmental protection should be taken into account in choosing the aeration equipments.
