摘要
AAO+MBR工艺是一种常见的城市污水处理工艺,但工艺运行过程中普遍存在总氮去除率较低、能耗较高的问题.通过采用VACOMASS曝气精确分配与控制系统,针对AAO+MBR工艺特点及运行情况,实时定量分配与控制相应曝气控制区的曝气量,满足对生物池的溶解氧和曝气量进行精细化控制的需求,从而实现提高总氮去除率以及节能降耗的目的.
AAO+MBR process is a popular treatment process in WWTP with the disadvantages of low remove rate and high energy.The VACOMASS air distribution and control system applied in AAO+MBR process,can distribute and control the air flow of each tank base on process demand,guarantee the air flow and DO(dissolved oxygen)of each tank which can be controlled precisely.Higher TN remove rate and less energy use are finally realized.
