摘要:
分别研究垂直流、水平流和沟渠型人工湿地对生活污水中总氮(TN)、总磷(TP)、氨态氮(NH4+-N)、生物耗氧量(BOD5)、化学耗氧量(CODCr)的去除效果。结果表明:不同类型人工湿地对生活污水中各种污染物的净化效果存在一定的差异,对污水去除率均呈倒“V”形变化规律,不同时间的去除率排序基本表现为反弹期>稳定期>恢复期>启动期;综合比较可知,不同类型人工湿地均能有效促进水质的净化,其中垂直流人工湿地对污水中TP、BOD5、CODCr的去除率较大,水平流人工湿地对污水中TN、NH4+-N的去除率较大;从出水水质稳定性来看,垂直流人工湿地出水各项指标较稳定,水平流、沟渠型较差,说明不同类型人工湿地对污染物的去除效果和机制不同;不同类型人工湿地植被地上、地下生物量所占的比例各不相同,地上部生物量、氮、磷含量均高于地下部,并且地上地下生物量比(A/U)均大于1,不同类型人工湿地植被地上和地下氮、磷累积量均呈“V”形变化规律,各时期积累量排序基本表现为反弹期>稳定期>恢复期>启动期。相关性分析表明,不同类型人工湿地植被氮、磷积累量分别与生物量、氮含量、磷含量呈显著(P<0.05)或极显著(P<0.01)的线性关系,由此推测,可以通过生物量和植被氮、磷含量来评价湿地植被对氮、磷的去除作用。
