摘要
通过川蔓藻和篦齿眼子菜对天津泰达景观河道水体氮磷去除的室内试验研究和实际水体测量结果,考察了不同形态的氮和磷酸盐的去除情况.在对试验结果(TN的去除率为42.40%～43.48%、NO3-N的去除率为38.02%～41.51%、NH3-N的去除率为96.54%～99.73%、PO4-P的去除率为94.31%～99.70%)和实际水体测量结果(TN的去除率为60.45%、NO3-N的去除率为51.83%、NH3-N的去除率为46.08%、PO4-P的去除率为66.39%)进行对比分析的基础上,提出了通过适时收割川蔓藻和篦齿眼子菜来去除水体中氮磷的有效途径,为防治再生水景观河道水体富营养化的发生发展提供理论依据和技术指导.
Based on the pilot research in indoor laboratory and through the actual water body monitoring on using Ruppia maritime and Potamogeton pectinatus to remove the nitrogen and phosphorus in TEDA Landscape River body,the removal efficiency of different form of nitrogen and phosphate was evaluated.The results demonstrated that using Ruppia maritime and Potamogeton pectinatus could significantly remove the nitrogen and phosphorus in water,especially in TEDA Landscape River body whose nitrogen and phosphorus nutrients was concentrated.Moreover,the removal efficiencies of TN,NO_3-N,NH_3-N,PO_4-P were 42.40%～43.48%,38.02～41.51%,96.54%～99.73%,94.31%～99.70% respectively in pilot researches,and they were 60.45%,51.83%,46.08%,66.39% respectively in actual monitoring water body.We also analyzed the effect difference between the both experiments results.It could be effective to control nitrogen and phosphorus content of the water body by timely harvesting the Ruppia maritime and Potamogeton pectinatus,which supported theory basis and technological references for operators to restrain the eutrophication bust in TEDA Landscape River body.
