【摘要】 淮河干流的突发性污染是危害淮河水质的重要原因之一,淮河干流的突发性污染,一般是由于源自支流的大污水团发生突发性汇入干流而形成的,这其中,颍河是淮河最大的支流,也被称为淮河水质好坏的“晴雨表”。以淮河干流突发性污染现象为研究对象,利用SMS软件建立鲁台子至凤台段的二维水动力模型,并在二维水动力模型的基础上建立二维水质模型,采用淮河干流发生突发性污染时期的实测数据对模型进行校准。研究中采用氨氮浓度为污染物指标,通过数值模拟得出突发性污染物的一般迁移规律,进一步模拟得出在不同来水量比和污染物浓度比情况下,颍河支流对淮河干流造成的污染程度,最终提出与流量比和浓度比相关的临界曲线,作为判断淮河是否可能发生突发性污染的判断依据。更多还原

【Abstract】 One of the most important reason for being a hazard to Huaihe River is the sudden Huaihe River pollution.The sudden Huaihe River pollution,which is generally due to the fact that a large waste water clumps from the tributaries import the main stream.Ying River is the largest tributary of the Huai River, which is also known as "barometer."of Huai River about the good or bad water quality.Taking the sudden phenomenon of pollution of Huaihe river as our object of study.By using SMS soft-ware, it is convenient for us to study by establish the two-dimensional water quality model of the basin which from Lu Taizi to Feng Tai and take advantage of the concentration of NH3-N as our pollute index. After we obtain the general migration of sudden phenomenon of pollution by numerical simulation,we can get further result,under the circumstance of different flow ratio and pollutant concentration ratio,that is the pollution of Huaihe river caused by its tributatry-ying river.In order to identify whether or not there is sudden phenomenon of pollution in Huaihe river,we have to find out the critical lines related to flow ratio and concentration ratio.更多还原
