摘要
通过浮床静态栽植豆瓣菜,研究其对4种不同程度富营养化水体的净化效果。研究结果表明,豆瓣菜对富营养化水体中总氮(TN)、总磷(TP)、氨态氮(NH4+-N)、硝态氮(NO3--N)均有较好的去除效果,去除率与水体初始浓度呈正相关。在试验初期,TN、TP、NH4+-N的去除速率较快,后期去除速率逐渐减慢。其中豆瓣菜对重度富营养化水体中TN、NO3--N和NH4+-N去除率最高,达90.73%、87.64%和95.54%,对极度富营养化水体中TP的去除率高达94.61%。与对照比,均差异极显著。
With static floating bed planting watercress,this paper studied the purification efficiency in different degrees of eutrophic water bodies. The results showed that,the removal rate of total nitrogen（TN）, total phosphorus（TP）, ammonia nitrogen（NH4＋-N） and nitrate nitrogen（NO3--N） in the eutrophic water body was positively correlated with the initial concentration of the water body, and have good removal effect. The removal rate of TN、TP and NH4＋-N fell quickly in the early days of the experiment, while gradually slow down. The removal rate of TN、NO3--N and NH4 ＋-N in severe eutrophication water bodies was higher than other groups,up to 90.73%,87.64% and 95.54%,the removal rate of TP in Eutrophication of water bodies reached 94.61%. The difference was very apparent compared with the control group
