- 摘要:
- 菖蒲、睡莲、香蒲、芦苇、藨草、荇菜和眼子菜对废水具有较好的净化效果，通过对这7种植物进行组合搭配，以只有洗沙的无植物空白试验作为对照组，测定试验前后的水中的氮磷指标。筛选合适的去污水生植物组合，以便在生产上推广应用。结果表明：供试植物在富营养化水体中均能正常生长，且对富营养化水体中的氮磷均有一定的吸收，香蒲+睡莲和芦苇+荇菜这2种组合氮磷去除率和生物量的增加相对较高。
- Abstract:
- Nymphaea tetragona，Typha angustifolia L，Phragmites communis Trirn，Nymphoides peltatum，Scirpus triqueter L.，Potamogeton perfoliatus L.and Acorus calamusLinn.are effective hydrophytes in cleaning waste water.This study was designed to screen a more efficient combination of such dydrophytes from different combination assays for developing an optimized decontamination group for practical usage.The blank control consists of washed sand without any hydrophytes growing.The nitrogen and phosphorus inside the water would be measured before and after the assays.The results showed that all hydrophytes grew well through the study，and each of them was effective in absorption of nitrogen and phosphorus.Comparatively，Nymphaea tetragona and Typha angustifolia L combination and Phragmites communis Trirn with Nymphoides peltatum combination were two groups that were more efficient in decreasing the nitrogen and phosphorus as well as promotion of biomass inside the entrophic water than others.
