摘要
通过开展芦苇与香蒲两种大型水生植物对水体的净化效果的动态研究,可以发现这两种植物均可以有效地去除水体中的TN与TP,去除率均在70%以上,其中芦苇的总体效果最好,对TN和TP的去除率分别为86.53%和78.17%;香蒲的去除率分别为72.05%和89.98%。经过试验期的净化作用,使原本处于劣V类水的水体质量提高到III类水以上。证明这两种植物可以作为小型景观水体的净水植物。
Water purifying effects of Phragmites australis( Car. ) Trin. ex Steud. and Typha orientalis Presl were researched. The results showed that two plants can effectively remove the TN and TP in water, the removal rate was above 70% ; the effect of Ph. australis was the best, its TN and TP removal rates were 87% and 78% respectively, T. orientalis of that were 72% and 90% respectively. Class V water was purified to Class III above after a purification trial period. It is proved that these two kinds of plants can be used as a small lake and alternative greening of man - made water body and water purification plant. These two kinds of plants can be used as water purification plant in small - scale landscape water body.
