| 摘 要： | 本研究提出了平原河网地区面源污染前置库技术,以去除地表径流中的氮、磷污染物质,提出其系统结构,以及关键技术,并开展了示范工程规模上的研究。工程实施后水质和景观得到明显改善,污染负荷得到削减。无降雨和小降雨输入期间,TN、TP、SS的平均去除率分别达到65.1%、45.3%、62.9%;强降雨时,降雨初期TN、TP、SS污染物去除率分别为70.5%、84.6%、90.9%,而处理后期,TN、TP、SS的去除率达到91.7%、96.2%、96.8%。

| Abstract: | Studies is made on the front damming technologies for NPS pollution control of river network in plain areas, so as to remove nitrogen and phosphorus of runoff. Its system structure and key technologies are presented and pilot project is implemented. It is found that water quality and landscape are improved dramatically after project implemented and pollution is reduced. During no rain or less rain season, elimination rate of TN, TP and SS is 65.1%, 45.3% and 62.9% respectively. During strong rain season, elimination rate of TN, TP and SS is 70.5%, 84.6% and 90.9% in the early period of rain and is 91.7%, 96.2% and 96.8% after treatment measures. |
