摘要
文章介绍了基于物理化学法的油田污水处理工艺流程,论述了工业控制中的均流控制,提出了三段式的磁滞回线的流体均流控制方法,并提出了基于PPM比值控制的污水加药控制方法及控制系统。
This introduces the process of oilfield sewage disposal based on physicochemical method,describes the flow balance control in the industrial control,proposes fluid flow balance control by three-segment hysteresis loop,and puts forward the control method of adding medicine in sewage based on ratio control by PPM.
