摘要：

本文通过刺苦草对富营养化水体净化效果的研究，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55cm。由此证明刺枯草可作为净化富营养化水体的优良生物材料之一。

Abstract:

In this paper, the efficiency of eutrophic water with Vallisneria spinulosa. It was shown that pollutant removals from polluted water using Vallisneria spinulosa such as TN、TP、NH4+-N、COD were 66.64%、90.02%、91.94%、71.17%，the concentration of pH could be reduced from 7.7 to 7.43, the concentration of DO could be raised from 6.956 mg/L to 16.406 mg/L and the transparency reaching 55 cm, demonstrating that Vallisneria spinulosa is one of excellent biomaterials on the eutrophic water.
