摘  要：
为了解凤眼莲对农村微污染小型水域的修复效果,以流经郑州郊区农村的十八里河河水作为对照(A组),向其添加有机质、氮磷营养物质的B、C 2组为微污染水样,采用凤眼莲静态培养,通过测定水样中化学需氧量(COD)、总磷(TP)、总氮(TN)及氨氮(NH3-N)含量,监测凤眼莲对污染水样的净化效果。结果表明,凤眼莲对水样中COD、TP、NH3-N的去除率增幅随时间增加而减小,在最初6d都表现出较高的去除率,且各指标的初始质量浓度越高,去除率亦越大;对TN的去除率增幅随时间增加表现为先增加后减小,TN的去除是一个相对缓慢的过程。在18d内凤眼莲对水样中COD、TP、TN和NH3-N的去除率分别介于69.27%～74.15%、69.20%～83.61%、71.86%～75.01%和64.26%～94.50%。可见,凤眼莲对微污染水域中COD、TP、NH3-N、TN均具有较好的净化效果,可用于修复该类水体。

摘  要：
To investigate the purification effect of water hyacinth on micro-pollution water,suburban river and its confected water by adding organic matter,nitrogen and phosphorus nutrients were chosen as water samples.The content of COD,TP,TN and NH3-N was monitored every 6 days through static culture experiment.The results showed that the amplifications of removal efficiencies of COD,TP and NH3-N by water hyacinth were decresed with time of culture,theremoval efficiencies were higher in the first 6 days;the higher that the initial concentrations of COD,TP,TN and NH3-N were,the higher that the removal efficiencies were.The amplification of removal efficiency of TN by water hyacinth increased at first and then decreased with time;the purification for TN was a relatively slow process.Removal rates of COD,TP,TN and NH3-N were 69.27%-74.15%,69.20%-83.61%,71.86%-75.01% and 64.26%-94.50%,respectively,in 18 days.In conclusion,water hyacinth had a good purification effect on COD,TP,TN and NH3-N,which could remediate the micro-pollution water.
