| 摘 要： | 将伊乐藻引入生态型河道受损水体修复中，通过室内试验系统地研究了伊乐藻的净化效果，结果表明：伊乐藻是修复受损水体较理想的材料，伊乐藻对总氮（TN）、总磷（TP）和CODM。的累计去除率，在夏季分别为61％、89％和34％；在冬季分别为25．74％、26．59％和10．93％；伊乐藻对水体的净化能力高于菹草和金鱼藻。同时，探讨了修复过程中可能存在的二次污染问题。通过宏观的质量平衡估算，1g伊乐藻在1a内可以从1L水体中去除TN、TP和CODMn分别达到44．57、15．42和31．13mg。

| Abstract: | The cleaning effect of Elodea Canadensis Michx was experimentally studied in laboratory. It was found that, in summer, the accumulated removal rates rate of TN, TP and CODMn of this kind of plant were 61%, 89% and 34% respectively; but in winter, the removal rates were reduced to 25.74%, 26.59% and 10.93%. The cleaning ability of Elodea Canadensis Michx is higher than that of Potamogegeton Crispus Linn and Ceratophyllum Demersum Linn. The potential problem of secondary pollution due to the decomposed Elodea Canadensis Michx was also discussed. According to the calculation of mass balance, the annual total removal rate of TN, TP and CODMn were 44.57mg, 15.42mg and 31.13mg per lg of Elodea Canadensis Michx in 1 L water respectively. |
