摘要
介绍了一种用于城市河道整治工程的生态浮床结构及养护工艺,并通过工程现场试验研究生态浮床的净水效果。试验结果表明,生态浮床显著降低了水体中的COD、NH_(3)-N、NO_(3)-N、TN和TP质量浓度。污染物质量浓度随与浮床距离增加呈指数衰减,净化作用主要集中在距浮床2~3 m范围内。浮床对TP的去除效率最高,达53.8%,优于对COD与氮类污染物的处理效果。研究证实生态浮床兼具良好的生态修复与景观价值,具有推广应用前景。
This paper introduces an ecological floating bed structure and maintenance technology for urban river regulation projects,and studies the water purification effect of the ecological floating bed through on-site engineering experiments.The test results show that the ecological floating bed significantly reduces the mass concentrations of COD,NH_(3)-N,NO_(3)-N,TN,and TP in water bodies.The mass concentration of pollutants shows an exponential decay as the distance from the floating bed increases,and the purification effect is mainly concentrated within the range of 2 to 3 meters from the floating bed.The floating bed has the highest removal efficiency for TP,reaching 53.8%,which is better than its treatment effect on COD and nitrogen-based pollutants.The study confirms that the ecological floating bed has both good ecological restoration and landscape value and has prospects for popularization and application.
