摘要
2011-2012年以哈尔滨市白鱼泡国家湿地公园为研究区域,选择区域内具有代表性的9种湿地植物为研究对象,应用小型模拟实验装置,通过计算湿地植物对污水的去除率,对区域内的典型湿地植物的净污能力进行研究。结果表明,9种湿地植物对生活污水均有净化效果,香蒲对生活污水的净化能力最强,最佳水力停留时间为5d。随着污水浓度的升高,7种湿地植物对COD、TN、和TP的去除率逐渐下降,且对低、中、高浓度污水的净化能力存在显著性差异,大部分湿地植物去除率显著高于对照。多种植物组合的湿地植物群落的净污能力要强于单种湿地植物的。
From 2011 to 2012, nine classic wetland plants were selected to study purification pollutants ability of typical wetland plants in Baiyupao national wetland park of Harbin. Through using small constructed system and calculating the removal rate of sewage, the purification ability of typical wetland plants was observed and studied. The results showed that nine wetland plants had the ability to remove the sewage. The purification ability of Typha orientalis Presl. was the best in the sewage. Comprehensive analysis to determine the HRT for five days was optimal hydraulic retention time. With the increase of concentration of sewage, the removal efficiency on COD, TN, TP of seven wetland plants decreased gradually and existed significant purification ability differences in low, medium and high concentrations of sewage（P〈0.05）, the removal rate of the majority of plant was significantly higher than that of the contrast（P〈0. 05）. Purification pollutants ability of the communities was significantly higher than the single-species.
