| 摘 要： | 介绍了泡板型浮岛在污染河水中的脱氮试验.实验表明浮岛植物的脱氮效能依次为:风车草>香根草>菖蒲.研究了去除负荷与覆盖率及进水负荷之间关系,结果表明以30%覆盖率为分界点,去除负荷与覆盖率之间的关系有明显的变化;去除负荷与进水负荷之间满足二次函数关系.最后得出了实验条件下的最适宜的覆盖率和进水负荷.

| Abstract: | We conducted a nitrogen removal test using floating islands in polluted rivers.The results show the nitrogen removal efficiency of Cyperus alternifolius exceeds that of Vetiveria zizanioides which in turn is greater than flagleaf.The relationship among removal loading,coverage rate and inflow loading was studied.The boundary of coverage rate was 30%.There was a significant change in the relationship between removal loading and coverage rate.The relationship between removal loading and inflow loading follows... |
