| 摘 要： | 针对污水处理厂进水水质和水量的不确定性,考虑进水水量、TSS、BOD5、TN、TP的区间变化,以出水时TSS、BOD5、TN、TP的质量浓度标准为约束条件,单元面积为决策目标,以费用最小为目标函数,建立基于一级动力学污染物去除模型的人工湿地污水处理系统区间数优化设计模型。该模型包含初沉池、人工湿地床(表面流和潜流式)两个单元,考虑了设计中的不确定性因素。实例计算表明,模型适用性较好。

| Abstract: | Considering the uncertain water quality and quantity of inflow to a sewage treatment plant and the variation interval of inflow water quantity, TSS, BOD5, TN and TP, an optimal wastewater treatment system for constructed wetlands was developed based on first-order kinetics. The constraint conditions of the model are effluent standards for TSS, BOD5, TN and TP. The objective function of the model is minimum cost, and the decision-making goals are the area of the primary sedimentation tank and the constructed wetland bed （SFCW or SSFCW）. Uncertainties in the system are considered. A case study shows that the model has high applicability. |
