If analytical equipment is available, purgesystem until oxygen content of residual gas is either less than or meets the process specification impurity level.
如果有分析仪器的话，一直净化设备，直到残留气体的氧含量或者低于或者满足工艺规范的纯度级别。

The closed back purgesystem and the condition of aerating turbulent flow can lighten the attenuation of membrane flux, at the same time, prevent the problem of nitrification inhibition.
通过密闭反冲洗系统、曝气紊流条件，可有效缓解膜通量的衰减，同时防止反应器内硝化抑制作用的产生。
