摘　　要：以南昌市前湖水系为研究对象,根据片区规划设计情况构建基于MIKE+平台的区域管网、河网、汇水区及水质模型,模型中包含了初期雨水截流管道、智能截流井、调蓄池等径流污染控制措施。采用污染物累积/冲刷模型,分析了单次降雨的径流污染情况。对智能截流井的3种控制方式进行了对比分析,并讨论了截流系统对径流污染的控制效果。模拟结果表明,径流污染具有明显的初期效应。智能截流井根据调蓄池水位进行控制时,既能发挥调蓄池的全部能力,又能较好地保证初期雨水不被稀释。截流系统对河道水质具有一定的保护作用,不同污染物的控制效果与其冲刷特性关系密切。This paper constructed the regional pipe network,river network,catchment area and water quality model of Qianhu River system in Nanchang City based on MIKE+platform according to regional planning.The model included runoff pollution control measures such as initial rainfall interceptor pipe,intelligent intercepting well and storage pool.The runoff pollution of a single rainfall was analyzed by pollutant buildup/washoff model.Three methods for intelligent interceptor well control were analyzed,and the performance of intercepting system for runoff pollution control was discussed.The simulation results showed that the runoff pollution had obvious initial effect.When the intelligent interceptor well was controlled according to the water level of the storage pool,the full capacity of the storage pool was utilized without obviously diluting the initial rainwater.The intercepting system was capable of protecting the water quality of the river to a certain extent,and the control performance of different pollutants was closely related to its washoff characteristics.
