超声微电解生物氧化污水处理过程控制系统设计

Process control system of the wastewater disposal equipment based on ultrasonic micro-electrolysis and biological oxidation

文章介绍了污水处理工艺控制问题,针对污水多元模块化组合式处理设备的特点采用了集散控制系统。该系统以个人计算机为上位机,以PLC为下位机。通过对污水处理系统特性的分析,针对其处理过程无法用精确的数学模型来描述的特征,提出将模糊控制的方法应用到污水处理当中。

In view of the common problems of the wastewater processing plant and the features of the processing equipment which deals with multielement and is modular and combinatory,the Distributed Control System(DCS) is designed. In the system,the PC is used as the upper-level unit and the PLC as the lower-level unit. Considering the characteristics of the wastewater treatment system in which the process can not be expressed by the precise mathematic model, the method of fuzzy control is applied to the wastewater treatment.
