| 摘 要： | 利用4个连续进水的垂直流人工湿地,比较分析水位对污染物去除效果的影响,研究湿地中植物对氮磷去除的贡献,阐析湿地中脱氮功能菌数量的演变规律。3个湿地栽种黄花鸢尾,水位分别控制在19、51和84cm,另一个湿地不栽种植物,水位为51cm。结果表明,水位对氮和有机物的去除有显著影响(p<0.05),栽种植物的湿地中,51cm水位时总氮去除率(67.4%～79.2%)最高,19cm水位时氨氮(85.3%～93.0%)和COD(81.8%～92.9%)去除效果最好。试验中黄花鸢尾均生长良好,植物吸收对总氮(Total nitrogen,简称TN)和总磷(Total phosphorus,简称TP)去除的贡献分别为19.2%～27.3%和14.7%～19.2%;植物地上部分发挥更重要作用,其TN和TP含量及对TN和TP的吸收量均高于地下部分。湿地表层基质中3种脱氮功能菌数量均随运行时间的增加而显著提高,亚硝化细菌和硝化细菌数量分别为10~4～10~6和10~5～10~7 MPN/g,随水位升高而减少;反硝化细菌数量为10~3～10~6 MPN/g,随水位升高而增加。
