　　污水处理厂的控制系统设计基于现代先进控制思想，采用分散控制、集中监测管理的控制方式，采用以和利时公司LK系列可编程控制器(PLC)为核心的控制系统。基于LK自动化控制系统应用于污水处理厂，完全能满足污水处理工艺的要求，提供了一种高可靠性、低成本、更优化的控制方案。
　　整个系统由1个中央控制室、4个现场PLC控制站组成。现场PLC控制站，由可编程序控制器(PLC)系统及检测仪表组成，对污水处理厂各工艺过程进行分散控制;再由中央控制室(CCR)，对全厂实行集中管理。中央控制室、PLC控制站之间的数据通讯采用高速的、实时的工业以太网，网络结构为环形，通讯速率为100Mbps，传输介质为光纤。中央控制站设于综合楼中控室;现场控制站设4个，分别位于进水泵房(1#PLC控制站)、变配电间(2#PLC控制站)、鼓风机房(3#PLC控制站)、污泥浓缩脱水机房(4#PLC控制站)，均采用和利时公司 LK系列PLC。
　　整个系统采用二级网络结构，即生产管理网和生产控制网，将过程实时数据、运行操作监视数据信息同非实时信息及共享资源信息分开，分别使用不同的网络。有效地提高了通讯的效率，降低了通讯负荷。生产管理网采用工业以太网，网络结构为环形，传输介质为光纤。生产控制网采用现场总线形式，采用PROFIBUS国际通用的开放式现场总线，传输介质为屏蔽双绞线。
　　污水处理厂自动化控制系统控制方式设计为现场设备就地手动控制、自动化控制系统远程手动控制、自动化控制系统远程自动控制三种控制方式。三种方式的级别由高到低依次为就地手动、远程手动、远程自动。
