【摘要】 为提升浐溪流域河道生态系统的完整性、可持续性及生物多样性，同时创造自然景观和亲水空间，研究了人工湿地在流域有机质污染水体治理中的应用。通过在浐溪流域实施人工湿地工程，采用水质指标测定、营养状态指数评估、污染指数法等方法评估人工湿地对有机质污染水体的治理效果，结果显示人工湿地显著降低了总磷和化学需氧量浓度，其中总磷降幅达58.9%,氨氮达82.3%,化学需氧量达43.5%。20天后净化效果稳定。此研究不仅验证了人工湿地在流域水体污染治理的高效性，也为类似水环境治理提供了可行方案。更多还原

【Abstract】 In order to improve the integrity, sustainability and biodiversity of the channel ecosystem in Chanxi Basin and create natural landscape and hydrophilic space, the application of constructed wetland in the treatment of organic matter polluted water bodies in the basin was studied. Through the implementation of the constructed wetland project in CED River Basin, water quality index measurement, nutrient status index assessment, pollution index method and other methods are used to evaluate the treatment effect of constructed wetland on organic matter polluted water bodies. The results show that the constructed wetland has significantly reduced the concentration of total phosphorus and chemical oxygen demand, among which total phosphorus has decreased by 58.9%, ammonia nitrogen has decreased by 82.3%, and chemical oxygen demand has decreased by 43.5%. After 20 days, the purification effect is stable. This study not only validates the high efficiency of constructed wetland in water pollution control, but also provides a feasible scheme for similar water environment control.更多还原
