| 摘 要： | 为了选择适合我国资料条件的河流控制断面污染物负荷估算方法,采用渭河下游潼关吊桥断面长期周水质监测数据和渭河华县断面逐日流量资料,选择了8种方法分别计算出潼关吊桥断面年污染负荷,并将各种方法的计算结果与实际负荷对比。结果表明:方法 7,即用流量加权浓度乘以年流量,分别计算丰、平、枯各季负荷,然后相加求和来计算年污染负荷的方法精度较高。最后对部分方法提出了改进措施。

| Abstract: | In order to select the estimation methods of pollution load for rivers,the paper choose 8kinds of methods to calculate the load of Tongguan drawbridge section by using weekly water quality data of Tongguan drawbridge and Huaxian' daily flow, and compared each result with the actual load respectively. The results showed that the precision of method 7is the highest.In method 7,period flux average concentration is multiplied by the period average flow to calculate the pollution load in wet,flat,dry season and then summed to calculate the annual pollution load. The paper finally proposed the improvement methods. |
