自动控制系统在污水处理中的应用

Application of Automatic Control System in Wastewater Treatment

根据中国污水处理运行管理的需要,简述了污水处理自动控制的国内外现状、设计思路和设计要求,并对目前污水处理设施运行管理中存在的问题,提出了一种操作简便,安装方便,便于管理的污水处理自动控制系统,并对系统的组成以及功能的实现作了初步的探讨。结合污水处理的工艺流程,简要分析了各个流程的控制特性。该系统以现场控制层和管理控制层两个层次为主,形成集中监视、分散控制的非阶层性控制策约。总结了自动控制系统与传统的人工控制相比在实际应用中的现实意义。

To meet the requirement of wastewater treatment management, it is presented the present situation at home and externally, design considerations and requirements of self-control system in wastewater treatment, and the wastewater treatment system is modified to aiming at solution of existing problems. The system is explained, such as composition and carrying out function. The control characteristic was analyzed to combine with the craft of wastewater treatment. The system is great part of locale control and manage, formed centralizing stakeout and decentralization control of the non - estate of control strategy. The practice meaning was summarized for application of self - control system in wastewater treatment.
