摘要
以凤眼莲浮床为研究对象,研究不同温度下浮床的净化效率、水生植物生长情况和植物体中氮磷的累积量。研究结果表明,凤眼莲浮岛对TN、TP的去除率与温度并不成正相关。浮岛的处理效果主要与浮岛植物的生物量有关,其处理效率随着生物量的增加而增加。凤眼莲浮岛25℃时处理效率明显高于35℃和15℃。在北方地区浮岛技术的生态学价值要显著于环境工程价值。
Taking Eichhornia crassipes floating bed as the research object,we studied the purification efficiency of floating bed,the growth of aquatic plants and the accumulation of nitrogen and phosphorus in plants at different temperature.The results showed that the removal rate of Tn and TP were not in positive correlation with temperature.The treatment effect of floating island was mainly related to the biomasses of floating island plants,and its processing efficiency increased with increasing biomass.The treatment efficiency of Eichhornia crassipes floating island at 25℃ was significantly higher than that at 35℃ and 15℃.In north area,the ecological value of floating island technology was superior to environmental engineering value.
