摘要
采用WASP6水质模型就实施南水北调中线工程对汉江襄樊段水质的影响进行了模拟.结果表明,南水北调中线工程调水后,即使按国家规定的污染物削减水平进行污染治理,汉江襄樊段水质仍将有明显下降,其中BOD5升幅为13.3%～26%(平均为19%),NH3-N升幅为14.3%～25%(平均为20.8%);DO值变化不大.襄樊市在调水前必须进一步加大污染防治的力度,以确保饮用水源的水质安全.
The influence of middle line of South-to-North project on water quality in Xiangfan section was simulated by using WASP6 water quality model. The result shows that after the middle line water diversion project is completed, the water quality in Xiangfan section will be dropped greatly,even if it is treated according to the national specified pollutants reduction level. Of which BOD5 rises in the range from 13.3% to 26% （19% in average）, NH3 -N from 14.3% to 25% （20.8% in average）, and no more variation in DO value. Therelore, Xiangfan City must strengthen the pollution control before water diversion, so as to ensure the safety of drinking water source.
