【摘要】：以宁波市前塘河水作为实验水体,采用不同水生植物及组合、生态浮岛复合技术净化水中污染物。经过14d的水培实验发现,沉水植物COD去除能力高于浮水植物和挺水植物;水生植物组合对COD的去除率相对较低,但去除率仍不低于79.9%。水生植物组合对氨氮的去除效果好于单一种类植物。沉水植物去除总磷的效果好于浮水植物与挺水植物,不同水生植物及组合的总磷去除率均大于44.0%。生态浮岛复合技术对废水中污染物的去除能力较强,实验10d时COD、氨氮、总磷去除率分别为97.1%、100.0%、73.8%。由此可见,水生植物和微生物的协同净化作用使生态浮岛复合技术对污染物的降解效果非常显著。
[Abstract]:Taking Qiantang River water in Ningbo as experimental water body, different aquatic plants and combinations and ecological floating island compound technology were used to purify pollutants in water. After 14 days of hydroponic experiment, it was found that the removal ability of COD in submerged plants was higher than that in floating plants and tappet plants, and the removal rate of COD in aquatic plant combinations was relatively low, but the removal rate was still not less than 79.9%. The removal efficiency of ammonia nitrogen by aquatic plant combination was better than that of single plant species. The removal effect of total phosphorus by submerged plants was better than that by floating plants and water-supporting plants. The removal rate of total phosphorus by different aquatic plants and combinations was more than 44.0%. The removal ability of pollutants in wastewater by ecological floating island compound technology was strong. The removal rates of ammonia nitrogen and total phosphorus in COD, were 97.1%, 100.0% and 73.8% respectively on the 10th day of the experiment. It can be seen that the synergistic purification effect of aquatic plants and microorganisms makes the degradation effect of ecological floating island compound technology very significant.
