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%。
The objective of this study is to investigate the purifying efficiency of Pistia stratiotes in aquatie wastewater including DO, NH4-N, NO2-N, NO3-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 NH4 .-N, NO, -N, NO3 -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.
