摘要
百乐卡是一种多级活性污泥污水处理工艺,溶解氧浓度控制是其典型的控制任务。针对污水处理过程中水质水量波动,溶解氧控制的非线性和滞后性,无法建立精确数学模型的问题,提出了采用模糊控制与PID控制相结合的方法。通过对溶解氧浓度控制系统的方案设计、硬件组成、模糊控制器设计及实现的剖析,给出了具体的工程实践,溶解氧变化曲线更趋平滑,系统运行能耗有效降低。
Biolak is a multilevel activity mud and sewage disposal processing, and the dissolved oxygen control is its typical control task. Aimed at the problem that the accurate mathematic model could not be built because of the fluctuation of water quality and quantity in sewage treatment process and the nonlinear and hysteresis of dissolved oxygen control, the article brings out using the control method of combination of FUZZY control and PID control. Through expounding the project design, the hardware component, the fuzzy controller design and implementation of the dissolved oxygen concentration control system, the specific engineering practice is given, the dissolved oxygen curve is smoother, and the system energy consumption is markedly decreased.
