- 摘要:
- 以菖蒲、鸢尾、芦苇、香蒲等4种植物为试材，比较了4种植物在不同时期对污水中NH4+-N和全磷（total phosphorus，TP）的净化效果，分析了植物不同部位试验前后生物量及氮磷含量的变化，探讨了影响植物净化效率的因素。结果表明：植物在快速生长时期的净化效率高于稳定时期的净化效率。4种植物对污水中NH4+-N的最大去除率表现为香蒲>鸢尾>菖蒲>芦苇，去除率分别为98.3%、98.2%、97.7%、96.8%，对污水中TP的最大去除率表现为香蒲>菖蒲>鸢尾>芦苇，去除率分别为96.7%、96.4%、95.9%、95.2%。植物对污水中NH4+-N和TP的去除率与植物地下部的生物量有关，地下部生物量大植物吸收的氮磷多，植物的去除率高。
- Abstract:
- This study compared the NH4+-N and total phosphorus (TP) removal rate of calamus，Iris tectorum，reed and cattail in different periods，analyzed the changes of biomass，and nitrogen and phosphorus content of different plants，also discussed the factors affecting purification efficiency of plant.The results showed that the purification efficiency of plants in the fast growth period was higher than the purification efficiency of plant in the stable period.The NH4+-N removal rate of the four plants followed that cattail>Iris tectorum>calamus>reed，and the removal rate was 98.3%,98.2%,97.7%,96.8%，the TP removal rate of the four plants followed that cattail>calamus> Iris tectorum>reed，and the removal rate was 96.7%,96.4%,95.9%,95.2%.The NH4+-N and TP removal rate were related to the biomass of the underground part of plant.
