不同水力负荷生态浮床对水体中氮磷的净化效果

Purification Efficiencies of Ecological Floating Beds to Nitrogen and Phosphorus under Different Hydraulic Loadings

选取4种生态浮床植物,研究不同水力负荷下(水力负荷0.5 m/d、1.0 m/d、1.5 m/d、2.0 m/d)各种植物生态浮床对水体中氮磷的净化效果。实验结果表明,水力负荷为0.5 m/d时对水体中氮磷净化效果最好,2.0 m/d净化效果最差,水力负荷为1.0 m/d与1.5 m/d时氮磷去除率相当。

Selected 4 plants for ecological floating beds, and studied the purification efficiencies to nitrogen md phosphorous under different hydraulic loadings （0.5 m/d, 1.0 m/d, 1.5 m/d and 2.0 m/d respectively）. The experi- nental results showed that the purification efficiency was best at the hydraulic loading of 0.5 m/d, worst at 2.0 m/d, md tile purification efficiency were equal at the hydraulic loadings of 1.0 m/d and 1.5 m/d.
