    摘要:

    全过程自动化控制是未来城镇污水处理厂的发展方向,但由于污水处理过程具有非线性、多变量、时变性等特点,自控系统中关键运行参数的测量以及控制决策的制定都存在困难,目前实际应用的系统大多停留在实现单一参数或单一反应器控制的层面上。自动控制策略是整个自动控制系统的头脑,是充分发挥系统软硬件效能、保证系统鲁棒性的关键。总结了城镇污水处理厂自动控制方案依据的数学模型,描述了活性污泥模型(ASM)和仿真基准模型(BSM)的基本特征,综述了自动控制策略在城镇污水处理曝气、化学除磷以及多目标优化控制方面的研究进展,分析了目前研究中存在的挑战和机遇,发现理论研究与工程实践相结合是加快城镇污水处理厂自动化进程的必要途径。

    Abstract:

    Urban wastewater treatment plants are oriented to the entire process control, while automatic control systems encounter many problems in parameter measurement and decision making because the wastewater treatment process is nonlinear, multivariable and time-varying. Thus most of control systems in practice are merely aimed at single parameter control or single rector control by now. Automatic control strategies are the brain of control systems, which could fulfill the potential of the hardware and software in the system and ensure the robustness of the system. Thus the mathematical models applied in the automatic control strategies of the urban wastewater treatment are introduced, and the characteristics of Activated Sludge Models (ASMs) and Benchmark Simulation Models (BSMs) are summarized. The automatic control strategies in terms of aeration, chemical phosphorus removal and multi-objective optimization control are described respectively, and the challenges and opportunities in the recent research are presented. Combining the theoretical research and the engineering practice is necessary for the automation process of the urban wastewater treatment plants.
