High variability, stringent effluent permits, and often extreme operating conditions define the practice of wastewater treatment in the chemical industry. This paper reviews the benefits and challenges of applying dynamic simulation to chemical-industry wastewater treatment plants by describing case studies at full-scale wastewater treatment plants (WWTP). The applications range from process troubleshooting to optimization and control. The applications have been valuable and useful in developing a deeper understanding of the plants as integrated systems. However there still remains substantial work to implement the dynamic simulations for daily real-time use by plant engineers and operators. This opportunity to improve plant operations is still largely untapped and will remain so until dynamic state estimation and data reconciliation are incorporated into simulation packages for use in developing the on-line simulations.
高变异性、严格的废水排放许可要求以及通常极端的运行条件，这些因素共同构成了化学工业废水处理的特点。本文通过描述全尺寸污水处理厂（WWTP）的案例研究，回顾了将动态模拟应用于化学工业污水处理厂的益处和挑战。其应用范围涵盖从工艺故障排查到优化与控制。这些应用在更深入理解作为集成系统的工厂方面具有重要价值且十分有用。然而，要让工厂工程师和操作员将动态模拟用于日常实时操作，仍有大量工作要做。改善工厂运营的这一机会在很大程度上仍未得到充分利用，并且在动态状态估计和数据协调被纳入用于开发在线模拟的模拟软件包之前，情况仍将如此。
