| 摘 要： | 以刺苦草植株为试验材料,通过对不同时期水中氮、磷、pH等的测定,研究其对富营养化水体的净化效果,为利用水生植物净化富营养化水体提供理论依据。结果表明:刺苦草对富营养化水体的TN、TP、NH4+-N、COD的去除率分别为66.64%、90.02%、91.94%、71.17%;pH从7.7降至7.43;DO从6.956 mg/L回升至16.406 mg/L,透明度达到55 cm。由此证明,刺苦草可作为净化富营养化水体的优良生物材料之一。

| Abstract: | The purification of eutrophicated water by Vallisneria spinulosa was studied by determining the TN,TP and pH,and this will be used to purify the eutrophicated water body with aquatic plants.The results showed that the removal rate of TN,TP,NH4+-N and COD with Vallisneria spinulosa were 66.64%,90.02%,91.94% and 71.17%,the pH value reduced from 7.7 to 7.43,the DO raised from 6.956 mg/L to 16.406 mg/L and the transparency was 55 cm.So Vallisneria spinulosa could be used to purify the eutrophicated water body. |
