摘要： 为了改善城市污水处理过程出水氨氮的处理效果,提出一种城市污水处理过程出水氨氮优化控制方法.首先,基于机理特性分析影响出水氨氮浓度的性能指标,建立一种基于自适应核函数的性能指标与控制变量的关联模型,并通过粒子群优化算法获取控制变量溶解氧浓度的优化设定值;其次,设计自适应模糊神经网络控制器,完成溶解氧浓度优化设定值的跟踪控制;最后,将出水氨氮优化控制方法应用于基准仿真平台BSM1.实验结果表明,该优化控制方法不仅提高了出水氨氮的去除效果,而且有效降低了能耗.

Abstract: To improve the treatment effect of effluent ammonia nitrogen in municipal wastewater treatment process, an optimal control method was proposed in this paper. First, the performance index of effluent ammonia nitrogen concentration was analyzed by using the mechanism characteristics. Then, a relationship model with the adaptive kernel function between the performance index and the control variables was established. Next, a particle swarm optimization algorithm was used to obtain the optimal solutions of dissolved oxygen concentration. After that, an adaptive fuzzy neural network controller was designed to complete the tracking control of dissolved oxygen concentration. Finally, the proposed optimal control method was applied to the benchmark simulation model No.1 (BSM1). The results demonstrated that the proposed optimal control method can not only improve the treatment effect of effluent ammonia nitrogen, but also effectively reduce the energy consumption.
Key words: municipal wastewater treatment process, effluent ammonia nitrogen, optimal control, adaptive fuzzy neural network controller
