通过构建生态浮床净化临江河重污染河水,全面考察了温度对浮床系统的影响.结果表明,温度对生态浮床系统有明显的影响作用,对生态浮床系统氮、磷净化效果的影响呈抛物线型.在水温为2~29℃时,生态浮床对TN和TP的去除率随温度的增加而明显增加;当水温超过29℃时,系统对TN和TP的去除率随温度的增加呈下降趋势;且温度对TN去除效果的影响要大于对TP的影响.研究表明,浮床系统的最佳运行水温为25~29℃,此时浮床植物的平均株高为209.9cm,对氮、磷的平均累积量分别为69.84,19.73g/m~2;浮床对TN和TP的去除率分别为38.7%~44.1%和38.6%~43.6%.

In order to investigate the effect of temperature on the ecological floating bed system,the ecological floating bed was constructed to treat heavily polluted fiver water of Linjiang River.The temperature influenced the ecological floating bed system significantly,among which the effect on the purification of TN and TP could be best described as a notably parabolic relationship.The removal efficiencies of TN and TP increased significantly with the increase in the water temperature from 2 to 29℃,but exhibited a decreasing trend with the increase in temperature was higher than 29℃.In addition,temperature showed a greater effect on TN removal than on TP removal.The optimal operating temperature Of the ecological floating bed was 25~29℃,when the average height of plants was 209.9 cm.the average amounts of nutrient storage in plant tissues was 69.84 g/m~2 for nitrogen,19.73 g/m~2 for phosphorus;and the removal efficiencies of TN and TP were 38.7%~44.1%,38.6%~43.6%,respectively.
