摘    要:南水北调中线北京段应急工程拟缓解中线全线通水前北京市的用水问题。该段工程为管涵输水渠道,全长80.3km。全封闭式管涵输水可以确保水质不受外部环境的污染,但封闭管涵造成的厌氧状态也可能导致一些水质问题。本文类比调查管涵长75km的北京市密云水库至第九水厂的输水管涵水体,对北京段应急工程的管涵输水水质进行了预测研究,并对其它相关的一些水质影响问题进行了分析,在此基础上提出了应急工程输水水质的保护对策及建议。

关 键 词:南水北调中线  调水工程  封闭管涵  输水水质

Abstract:The emergency water supply project of the Beijing Section of the Middle Route Project of the South-to-North Water Transfer has been constructed, aiming at solving the water issues in Beijing before the whole Project is completely operated. An enclosed conduit, 80. 3km in length, is used in this section, which could effectively avoid water pollution on the way, but would weaken the re-oxygenation ability of water. Thus the transfer water quality is predicted by a comparative analysis of the water in the pipe culverts between the Miyun Reservoir and No. 9 Waterworks. Other relevant impacts are also studied. Based on the study, some countermeasures for water quality protection are put forward accordingly.
Keywords:Water Transfer Project from South-to-North ( middle route )  water transfer  enclosed conduit  water quality
