抚顺市三宝屯污水处理厂自控系统设计

污水处理过程是一个复杂的非线性、多变量的控制过程，传统污水处理厂的控制多采用常规的仪表进行控制，以手动控制为主，完全依赖于操作工人掌握的知识和经验。采用这种方式的水处理质量不稳定，劳动生产率低，系统信息分散。为了提高水处理质量，降低水处理成本，必须应用先进的自动控制设备和技术，设计一套全自动控制的污水处理厂自控系统。

The Automatic System Design of Sewage Treatment Plant in Sanbao Village,Wushun City

Sewage treatment is a complex nonlinearity and multivariable control process. The traditional sewage treatment plants usually adopt regular apparatuses to control, which are normally controlled by hands and completely based on operators＇ knowledge and experiences. Therefore, sewage treatment that relies on this traditional method is featured by low quality, low efficiency and with decentralized information system. In order to improve the quality of sewage treatment and reduce the treatment costs, advanced automatic control equipments and techniques should be applied. In this case, a set of automatic controlling system could be built in a sewage treatment plant.
