摘要
为研究水生植物净化水体的效果,研究不同密度的轮叶黑藻在静、动态水体中对污水处理的净化效果.结果表明,轮叶黑藻对总氮、总磷、化学需氧量均具有较好的去除效果.在静水、轮叶黑藻的密度为3束/dm^2的条件下,对地表劣Ⅴ类水的净化效果最佳;在动水、轮叶黑藻的密度为1.9束/dm^2的条件下,对水质的净化效果最佳.在受污染水体中可适当地种植轮叶黑藻进行生态修复.
In order to study the purification effect on water body of aquatic plants,the article chose representative submerged plant Hydrilla verticillata to investigate the purification effect of different density Hydrilla verticillata’s purification effect on sewage disposal in both static and dynamic water body.The result shows that,Hydrilla verticillata has good removal effect on total nitrogen,total phosphorus,and COD.The purification effects on five types of poor water on surface of the earth shows optimum under the condition ofρ3 is 3 beam/dm 2 of Hydrilla verticillata in static water;and the purification effect on water quality reaches the best under the condition ofρ2 is 1.9 beam/dm 2 of Hydrilla verticillata in dynamic water.Hydrilla verticillata can be configured appropriately in polluted water for ecological restoration.
