摘要
研究了几种人工生态强化净化技术对滞流景观水体水质保持与改善的效果,结果显示:碳素纤维生态草表面可形成稳定的生物膜,对水质改善的效果最好,NH3-N、TN、TP和COD的去除率可分别达到94%、92%、92%和85%,生态草对浮游藻类增长和水体色度增加均有较好的抑制作用,并且随着密度的增加作用增强;间歇曝气充氧法对水中氮磷的去除和对色度增加的抑制效果较好,但与其他方法相比,曝气扰动会使水中COD增高,还可能会促进藻类的增殖;美人蕉浮岛对氮磷的去除和对色度增加的抑制作用低于生态草和间歇曝气,但对COD的去除和抑藻效果均好于间歇曝气。
The comparison result of several manual strengthened methods to improve the water quality of landscape river showed that the surface of cellulose-ecological-grass could form stable biofilm, and so it worked best in the improvement of water quality. Under the action of ecological grass, the removal rate of NH3-N、TN、TP and COD could achieve 94%、92%、92% and 85%, respectively. Ecological grass also played a better role in curbing the multiplication of floating algae and the increase of water color. And the density of ecological bigger, the improvement effect of water quality was stronger. Intermittent aeration method had good effect on the removal of nitrogen and phosphorus, also could resist the increase of color, but with higher COD and frequent algae proliferation compared to other methods. The comprehensive effect of aquatic canna floating island on the maintenance of water quality from the respect of nitrogen, phosphate, COD removal and algae inhibition was better than intermittent aeration. But the role of aquatic canna in controlling the increase of water color was little worse.
