水花生去除富营养化水体中氮磷及抑藻效果的实验研究

A Experimental Study on the Removal the Nitrogen Phosphorus of Eutrophication-water and Restraint of Algae by Alternanthera Philoxeroides

研究了水花生对超富营养化水体、富营养化水体的总氮总磷的去除能力及抑藻效果。实验结果表明,水花生对总氮总磷的平均去除速率用平均生物量法计算处理3最高,分别是79.2mg/kg·d,23.7mg/kg·d;而对总氮总磷的相对去除率处理5最高,分别是91.6%和95.1%;同时研究了水花生的生长量、抑藻效果、体内总氮总磷含量,进一步探索了水花生在水质净化中的应用。

Has studied the Alternanthera Philoxeroides to the ultra eutrophication water body, eutrophication water body total nitrogen total phosphorus elimination ability and damps the algae effect..Had ended after the experimental cycle,the Alternanthera Philoxeroides processes 3 high to the total nitrogen total phosphorus average elimination speed with the average biological mensuration computation,Respectively is 79.2 mg/kg＊d,23.7 mg/kg＊d,But to total nitrogen total phosphorus relative elimination rate processing 5 highest,Respectively is 91.6% and 95.1%,Simultaneously studied the Alternanthera Philoxeroides growth quantity,has damped the algae effect,in vivo total nitrogen total phosphorus content,Further explored the Alternanthera Philoxeroides to purify in the water quality the application.
