不同水力负荷生态浮床对水体中氮磷的净化效果

摘要

选取4种生态浮床植物，研究不同水力负荷下（水力负荷0．5m／d、1．0mid、1．5m／d、2．0m／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0．5m／d时对水体中氮磷净化效果最好，2．0m／d净化效果最差，水力负荷为1．0m／d与1．5m／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.
