摘　　要：受高含铁煤矿废水污染的都匀市杨柳街河,经采用在河流上修建一座人工水坝形成小水库,在自然曝气和小水库库区沉淀作用下,使得部分河段水中总铁浓度有了显著降低,河水颜色由深黄变绿,水质有了明显改善。本文通过这座水坝修建前后的河水水质监测结果对比,验证了其治理效果。The Yangliujie River in Duyun City was polluted by wastewater from high-iron coal mines.An artificial dam was built on the river to form a small reservoir.Natural aeration and sedimentation in the small reservoir area resulted in the decrease of the total iron concentration in some river sections,where the color of the river has changed from dark yellow to green,and the water quality has been significantly improved.This paper verifies the pollution control effect by comparing the monitoring results of the river water quality before and after the construction of the dam.
