| 摘 要： | 沉水植物常用于水质净化与生态修复工程.本实验通过室内模拟与测定,分析比较4种常见沉水植物在6个种植密度梯度(0.5g·L-1～3g·L-1)下对世博后滩公园生态水系氮、磷污染物的去除率.30d模拟实验结果表明,4种沉水植物对水体中过量氮、磷均有较高的去除率,在种植密度为3g·L-1时,轮叶黑藻(HydriHa verticillata)对TN去除率最高达到6%,马来眼子菜(Potamogeton malaianus)对TP的去除率最高为88%.在种植密度为0.5g·L-1～3g·L-1的范围内时,各沉水植物实验组随种植密度的增大,对氮、磷的去除率升高.

| Abstract: | Submerged plants are commonly used in water purification and ecological restoration.The removal rates of four common submerged plants on nitrogen and phosphorus in the water of Houtan Park were analyzed through 30 days laboratory simulation and determination under six different planting densities.The results show that four submerged plants have significantly high removal rates of excessive nitrogen and phosphorus in eutrophic water.Removal efficiency of total nitrogen(TN)by Hydrilla verticillata reaches the... |
