摘要:
通过模拟垂直流人工湿地污水系统,研究湿地植被鸢尾(Iris tectorum Maxim.)、菖蒲(Acorus calamus L.)、茭白(Zizania latifolia)和芦苇(Phragmites communis Trin.)对生活污水总氮(total N,简称TN)、总磷(total P,简称TP)、氨氮(NH4+-N)、硝氮(NO3--N)、生物耗氧量(biochemical oxygen demand,简称BOD5)和化学耗氧量(chemical oxygen demand,简称CODCr)的去除效果。结果发现,人工湿地4种植被对各种污染物的净化效果存在一定的差异,净化效果基本表现为鸢尾和芦苇高于菖蒲和茭白;人工湿地4种植被对氮素的去除效果较好,对TP的去除效果较差,说明4种湿地植被对生活污水中氮素的吸收效果较好;人工湿地4种植被地上部和地下部生物量、根系活力和基质酶活性均表现为鸢尾和芦苇高于茭白和菖蒲;4种植被地上部生物量均大于地下部生物量,就植株体内的N、P含量而言,地上部分N和P积累量高于地下部分;回归分析结果表明,人工湿地不同植被N、P积累量分别与生物量N、P含量呈显著的线性关系(P<0.05),由此推测,通过生物量和植被N、P含量来评价湿地植被对N、P去除的作用;相关性分析结果表明,人工湿地植被对生活污水各指标的去除率与植被自身生理特性密切相关,从相关系数来看,人工湿地植被对生活污水各指标的去除率与其根系活力和基质酶活性密切相关;除此之外,人工湿地植被对TN的去除与自身体内氮素密切相关,对TP的去除与自身体内磷素密切相关。
