| 分别以凤眼莲、黄花水龙、空心莲子草、水鳖和浮萍5种水生植物对总氮超过40mg/L 的生活污水进行了3个月的生态修复处理，结果表明水生植物对总氮具有较好的去除效果，平均水平达到60%以上，五种水生植物的除氮率最高的为凤眼莲（86%），空心莲子草最低（58%）。不同水生植物对其他形态氮的去除率也具有各自的特点，凤眼莲对氨氮的去除率最高（88%），黄花水龙最低（14%）；浮萍和凤眼莲对硝态氮的去除率相当，高达85%以上，空心莲子草对硝态氮吸收较低（23%）。 |
| 英文摘要: |
| The three-month ecological restoration treatment on the sewage of TN more than 40mg/L by the five aquatic plants of
water hyacinth, yellow water dragon, alligator grass, water turtle and duckweed. The results indicate that the average removal of TN is more than 60%, the highest removal with 86% is water hyacinth and lowest with 58% is alligator grass. The removal of the other forms of nitrogen in Different aquatic plants has their own characteristics. The highest and lowest of ammonia nitrogen removal rate are water hyacinth 88% and yellow water dragon 14%, duckweed and water hyacinth have more than 85% nitrate removal, and alligator grass is 23%. |
