活性污泥法处理中污泥总量控制的讨论

Discussion of Total Sludge Mass Control in Activated Sludge Process

污水生化处理过程中涉及到的变量很多,但是真正可以用于调控污水处理厂运行过程的变量却很少,这使得污水处理厂的调控方式不是很灵活。重点研究了污泥总量控制,分别讨论了剩余污泥排放量、回流污泥排放量这两个操作变量在调控污水处理过程中的表现。

There are many variables involved in the process of biological sewage disposal,but only few of them can really be used as control variables in the control process,and this makes the control means of sewage disposal not that flexible.This paper discusses two of these variables,residual sludge wastage,re- gurgitant sludge wastage,and figures out their different effect in the control process.
