摘要
对鱼草、伊乐藻、金鱼藻三种沉水植物在不同条件下净化受污水体进行了研究。研究表明,三种沉水植物能较好地去除N、P类营养物,对NH3-N、PO43-的去除率可分别达85%～95%和70%～80%,同时可提高水体的DO、pH和透明度,对高锰酸盐指数也有一定的去除效果。综合分析表明,三种沉水植物对受试水体都有良好的净化效果,其中鱼草比较适用于园林水体修复。
Research on purification of polluted water by different submerged macrophytes, Cabamba carolirruma Gray, Elodea Canadensis and Ceratophyllurn demersurn L., was carried out under different conditions. The results showed that three species of submerged macrophytes were capable of removing nutrients, such as ammonium nitrogen and phosphorus. The removal of NH3-N and PO4^3- reached ＇about 85%-95% and 70%-80% respectively. At the same time, the three species could increase the dissolved oxygen, pH and transparency of water, and effectively remove the CODMn. It was shown that the three submerged macrophytes had good effect in remediation of the polluted water, and Cabamba carolimana Gray was better for remediation of park water.
