摘要：在快速城市化地区，建立污水处理设施以改善重污染河流的水质日益重要。为了最大限度减少废水处理成本同时又满足一定的水质标准，优化模型被广泛用于确定针对不同污染源的污染物处理级别。水质评估通常是在规定的空间或时间点。因此它不能反映具有明显时空变化的感潮河流的整体状况。在本文中，提出新的时空水质标准并应用于中国深圳的污水处理系统的优化。新的标准考虑在整个模拟河段上和其模拟全时间过程中，河流水质是否违反特定水质标准。结果表明，基于针对整条河流的一个长时间段内的水质，而并非仅仅限于在规定的空间和时间点所提出的水质标准的优化措施更有利于提高污水处理系统的性能。此外，应用新的新标准在进行成本和水质优化过程中其帕累托解集的收敛性和覆盖度更优。因此，它应该被当作污水处理系统规划中衡量感潮河流空间和时间变化的标准。

Abstract: There is an increasing need to establish wastewater treatment facilities for improving water quality of heavily polluted rivers in rapidly urbanizing areas. Optimization models are widely used to determine the pollutant removal levels at different pollution sources, with the aim of minimizing the wastewater treatment cost and satisfying certain water quality criteria. Water quality is usually evaluated in a prescribed space or time point. Thus it cannot reflect the overall status of a tidal river that has significant spatio-temporal variations. In this paper, new spatio-temporal water quality criteria, which consider the water quality violation against specified water quality standards during the whole simulation period of time for the entire river simulated, are proposed and then applied to optimization of a wastewater treatment system in Shenzhen, China. The results indicate that the optimization based on the proposed criteria facilitates an improved performance of wastewater treatment systems in terms of water quality along the whole river during a long time period, instead of just in a prescribed space or time point. Furthermore, use of the new criteria derives a better Pareto front of cost and water quality in terms of convergence and coverage compared with the conventional criteria and thus they are recommended as the water quality criteria to measure spatial and temporal variation in a tidal river for wastewater treatment system planning.
