水处理系统不能小觑的曝气和那些曝气头

曝气类型大体分为两类:一类是鼓风曝气,一类是机械曝气。 鼓风曝气是选用曝气头分散板或分散管在水中引进气泡的曝气方法。一般乙烯厂的污水处理多选用这种方法。机械曝气是指利用叶轮等器械引进气泡的曝气方法。

这样,活性污泥才干处在佳的降解有机物的状况。依据实验标明,曝气池中溶解氧保持在3~4mg/L为宜,若供氧缺乏,活性污泥功用差,导致废水处理效果下降。为确保有满足的供氧,有必要依托一种设备来完成,例如曝气头

曝气拌和正是如此,详细的做法就是:减少气泡的巨细,添加气泡的数量,进步液体的紊流程度,加大曝气头的设备深度,延伸气泡与液体的触摸时刻。曝气设备正是根据这种做法而在污水处理中被广泛选用的。

鼓风曝气设备

鼓风曝气体系由鼓风机、曝气头和一系列连通的管线组成。鼓风机将空气经过一系列管道输送到设备在池底部的曝气头,经过曝气头3d走势图带连线图,使空气构成不同尺度的气泡。

气泡在曝气头出口构成,尺度则取决于空气分散设备的方式,气泡经?过上升和随水循环活动,最后在液面处决裂,这一进程发生氧向污水中搬运的效果。鼓风体系的曝气头首要分为微气泡、中气泡、大气泡、水力剪切、水力冲击及空气升液等类型。

4 微气泡曝气头

微气泡曝气头也称微孔曝气头,选用多孔性资料如陶粒、粗瓷等掺以适当的如酚醛树脂一类的粘剂,在高温下烧结成为分散板、分散管和分散罩的方式。依照设备的型式,可分为提升式微孔曝气头及固定式微孔曝气头
