明渠突发水污染导流退水工况的模拟

Simulation of diversion and recession flow for sudden water pollution accidents in open channel

我国是一个水污染事故多发的国家,在南水北调工程全面通水前,需要提前针对可能发生的突发水污染事故开展研究。通过利用SMS水动力学软件,以中线某段为例,模拟分析明渠中水的流动状态及突发水污染时污染物的扩散过程;并在此基础上分析采用设置导流坝配合退水渠进行污染团导流的应急处置效果。以期为渠道管理和污染事故处理提供理论和技术支持。

China is a country with water pollution accidents occurring frequently.Before full completion of the South-to-North Water Diversion project,we need to research the sudden water pollution accident that may occur in advance.Using the hydrodynamic software SMS,the flow state in open channel and the pollutants diffusion process were simulated when sudden water pollution occurred in a typical segment of the middle route main channel.Based on that,the emergency disposal effect with the use of setting the diversion dam and escape canal was analyzed.It provides technical support for channel management and pollution accident treatment.
