摘 要:在变化的水质条件下,透光率脉动混凝投药控制系统设定值的在线自修正问题,一直影响这一技术在常规法度水中的应用。利用Takagi-Sugeno模糊推理形式,设计了透光率脉动混凝投药系统设定值在线自修正模糊逻辑推理系统,完成了基于SIEMENS小型可编程控制器的透光率脉动混凝投药模糊控制系统的编程。利用某处理量为400L/min的中试试验模型验证了该系统的性能。中试试验结果表明,根据水质参数变化,该系统能够及时调整系统设定值,调节投药量,并且在整个调节过程中沉淀出水稳定、合格。The on - line modification of coagulation control system set points, based on fluctuation of transmitted light, has its influence on the application of this technology in water treatment plants for a long time. A fuzzy control system incorporating the photometric dispersion analyzer was utilized in this coagulation control system. Proposed is a fuzzy logic inference control system by using Takagi and Sugeno' s fuzzy if- then rule for the self - correction of set points on line. Programmed is the dosing rate fuzzy control system in SIEMENS small - scale programmable logic controller. A 400 L/min middle - scale water treatment experiment was utilized to simulate the reaction. With the changes in raw water quality, the set point as well as coagalant dosing rate was modified correctly in time, and the residual turbility before filtration was eligible and stable. Results show that this fuzzy control system performs well on the auto - coagulation control system based on the technology of transmitted light.
