摘要:通过在北京市延庆县建立湿地植物筛选池,模拟自然条件下7种湿地植物和7种植物配置对总磷(TP)、总氮(TN)、化学需氧量(COD)的去除效果。结果表明:不同湿地植物及组合对COD和TN、TP的净化效果不存在显著性差异(P>0.05)。除香蒲夏秋两季对COD的净化效果存在显著性差异外(P<0.05),其他湿地植物及组合对COD的净化效果不存在显著性差异(P>0.05)。7种湿地植物单种和7种湿地植物配置都表现为是夏季对'TN的去除效果要优于秋季。除芦苇+睡菜、香蒲+蒿柳夏秋两季对TN的净化效果存在显著性差异外(P<0.05),其他湿地植物及组合对TN的净化效果不存在显著性差异(P>0.05)。7种不同湿地植物配置对TN的净化效果存在显著性差异(P<0.1)。夏秋两季。不同湿地植物单种之间对TP的净化效果不存在显著性差异(P>0.05);而夏季不同湿地植物配置对TP的净化效果存在显著性差异(P<0.05),秋季不同湿地植物配置对TP的净化效果不存在显著性差异(P>0.05)。除菖蒲+茭白、芦苇+睡菜夏秋两季对'TP的净化效果存在显著性差异(P<0.05)外,其余湿地植物及组合对TP的净化效果不存在显著性差异(P>0.05)。
A wetland plant screening was constructed at Yanqing County, Beijing to simulate the effectiveness of 7 natural wetland plants and their combinations in purifying eutrophic water and removing TP, TN and COD. The results showed that the purification effectiveness of wetland plants and any of their combinations were not significantly different (P〉0.05) for COD, TN and TP; no significant difference (P〉0.05) exists on COD purification between summer and autumn, except for Typha orientalis (P〈0.05). These 7 wetland plants and 7 combinations showed 1) higher effectiveness on TN removal in summer than in autumn; 2) no significant difference on TN purification between summer and autumn (P〉0.05), except for Phragrnites australis + Menyanthes trifoliate, Typha orientalis + Salix viminalis (P〈0.05); 3) no significant difference on TP purification by any individual wetland plant between summer and autumn (P〉0.05); 4) no significant difference on TP purification between summer and autumn, except for Typha orientalis + Zizania aquatic, Phragmites australis + Menyanthes trifoliata (P〈0.05); 5) but a significant difference on TN purification among 7 different wetland plants combinations (P〈0.1).
