摘    要:研究了水浮莲(Pistia stratiotes)在可控条件下对水产养殖排放污水中的氨氮、亚硝酸氮、硝酸氮、总氮、总磷、化学耗氧量等水质指标的去除效果。试验结果表明,水浮莲对水体中的氨氮、亚硝酸氮、硝酸氮、总氮、总磷和COD均有一定的净化效果,各水质指标的含量均有不同程度的降低,其最大去除率分别为42.4%、47.5%、23.2%、5.80%、51.5%和25.9%。

关 键 词:水产养殖  排放水  水浮莲  水质净化  去除率

Abstract:The objective of this study is to investigate the purifying efficiency of Pistia stratiotes in aquatic wastewater including DO,NH 4-N,NO-2-N,NO-3-N,TN,TP,COD.The result indicates that Pistia stratiotes has prominent purification function on the nitrogen,phosphorus and organic matter in the wastewater.The maximal removal rates of NH 4-N,NO-2-N,NO-3-N,TN,TP and COD are 42.4%,47.5%,23.2%,5.80%,51.5% and 25.9% respectively.It leads to extensive using for water treatment of aquiculture.
Keywords:aquiculture  aquatic wastewater  Pistia stratiotes  water quality purification  removal rate
