    摘要:

    针对控制分流制系统径流污染的调蓄设施的设计,尝试引入反映径流与污染负荷之间函数关系的质量冲刷曲线,并利用SWMM(storm water management model)计算所需数据,作为调蓄规模的确定依据;同时辅以多属性决策模型,综合多种因素,对调蓄设施进行优化设计,从而建立一种较为科学、简明的控制分流制径流污染调蓄设施的优化设计方法。以山西省某县为实例进行计算,结果表明相比于传统的末端调蓄方案,优化方案的总调蓄规模增加6.3%,节点平均调蓄规模减少了47%,径流污染控制效果提升了5%,且能削减高重现期下的系统溢流。优化方案在实现径流污染控制目标的同时降低内涝的风险,表明了该方法的有效性和可行性。

    Abstract:

    Aiming at the design of regulation and storage facilities for pollution control in the separate system, this paper attempts to introduce the mass flush curve reflecting the functional relationship between runoff and pollution load, and use the data calculated by SWMM(storm water management model)model to determine the regulation and storage scale. At the same time, the multi-attribute decision-making model is used to optimize the design of the regulation and storage facilities, so as to establish a more scientific and concise optimization design method to control regulation and storage facilities of runoff pollution in the separate system. Taking a county in Shanxi Province as an example, the results show that compared with the traditional terminal regulation and storage scheme, the total regulation and storage scale of the optimized scheme is increased by 6. 3%, the average node regulation and storage scale is reduced by 47%, the runoff pollution control effect is improved by 5%, and the system overflow in the high return period can be reduced. The optimized scheme can achieve the goal of runoff pollution control and reduce the risk of waterlogging at the same time, which shows the effectiveness and feasibility of the optimized scheme.
