引滦输水污染物对于桥水库水环境的影响

对引滦输水期及非输水期引滦沿线入库水体污染物研究，分析水体中悬浮物、TN、TP等污染物对于桥水库水环境质量产生的影响。结果表明：对于桥水库的水环境产生影响的主要水质指标为TN、TP，其主要来源为引滦输水的上游水库；悬浮物及重金属在引滦输水沿线水体中含量较大，主要来源于沿线两岸的铁矿砂及选砂堆积物，但进入于桥水库前沉积量较大，对水库水环境影响较小。

Effects of water pollutants from Luanhe-Tianjin water diversion on water environment of Yuqiao Reservoir

In this study , the characteristic water pollutants flowing into the Yuqiao Reservoir from the Luanhe-Tianjin Water Diversion during water diversion and non-water diversion periods were studied , and the effects of suspended matter , total nitrogen , and total phosphorus on the water environment of the reservoir were analyzed . The results show that the main factors influencing the reservoir ’ s water environment were total nitrogen and total phosphorus , which came from the upstream reservoir .There were large amounts of suspended matter and heavy metals in the water during the diversion , which mainly came from the tailings and deposits on both sides of the water diversion route .As the suspended matter and heavy metals were deposited in large amounts before they entered the Yuqiao Reservoir , they had an insignificant effect on the water environment of the reservoir .
