| 摘 要： | 利用聚乙烯板作为浮床栽植水芹(Oenanthe javanica),观测其对4组不同富营养化程度水体的净化效果。结果表明,水芹对总磷(TP)有较好的去除效果,初始浓度越高去除率越低,去除率范围53.3%～84.0%;水芹对低于5mg/L的总氮(TN)有较好的去除效果,去除率也随初始浓度升高而降低,去除率范围36.1%～85.7%,如果总氮浓度过高(达到20mg/L左右),去除效果不明显。试验组氨氮(NH3-N)的浓度虽然有明显的降低,但与对照组比没有明显优势,水芹对亚硝酸盐氮(NO2--N)的去除作用不明显,硝化细菌对氨氮和亚硝酸盐氮的去除起主要作用,水芹通过降低水中总氮水平对氨氮和亚硝酸盐氮有一定间接的去除作用。在整个试验过程中,各组高锰酸盐指数(CODMn)维持在较低水平(<3mg/L),未观察到栽植水芹对高锰酸盐指数的降低作用。

| Abstract: | Java waterdropwort (Oenanthe javanica) were planted in Expandable polyethylene boards, to detect the purification effect on eutrophic water at 4 different levels. The results showed that Java waterdropwort had a high ability to remove total phosphorus (TP), and the water with higher initial concentration had a lower removal rate. The removal rates of TP ranged from 53.3% to 84.0%. Java waterdropwort had a high ability to remove total nitrogen (TN) when the concentration of water was lower than 5mg/L. The groups with higher initial concentration of TN also had a low removal rates. The removal rates of TN ranged from 36.1% to 85.7%. There was almost no purification effect when the concentration higher than 20mg/L. Although concentrations of ammonia nitrogen(NH3-N) in treatment groups decreased obviously, and there was no advantage compared to the control. Java waterdropwort had few purification effects on the concentration of nitrous nitrogen(NO2-N). Nitrobacteria played an important role in the removal of ammonia nitrogen and nitrous nitrogen. Java waterdropwort could remove ammonia nitrogen and nitrous nitrogen indirectly through the decrease of total nitrogen. The permanganate index kept at a low level (<3mg/L) during the whole experiment period, the removal effect of permanganate index had not been observed. |
