摘要
采用模拟栽植法对小叶丁香、小叶女贞、紫穗槐、胡枝子、东北连翘、金山绣线菊、红瑞木7种园林绿化常用灌木净化污水中TP、TN、COD的效果进行了比较研究。结果表明:各供试材料净化污水中TP、TN、COD的效果明显。其中,对TP的净化效果,金山绣线菊>紫穗槐>红瑞木>小叶女贞>胡枝子>小叶丁香>东北连翘;对TN的净化效果,紫穗槐>金山绣线菊>胡枝子>小叶女贞>红瑞木>东北连翘>小叶丁香;对COD的净化效果,金山绣线菊>红瑞木>小叶丁香>紫穗槐>胡枝子>小叶女贞>东北连翘。随着生长时间的延长,各供试材料对污染物的净化率呈现先下降后趋于稳定的变化趋势。
The potted simulation method was used to compare the purification effect of seven kinds of common shrubs for landscaping on TP,TN and COD in sewage.The results showed that these shrubs all had obvious purification effect on TP,TN and COD in sewage.The purification effect on TP was as follows,Spiraea japonica‘Gold Mound’>Amorpha fruticosa>Cornus alba>Ligustrum quihoui>Lespedeza bicolor>Syringa microphylla>Forsythia mandschurica.The purification effect on TN was as follows,Amorpha fruticosa>Spiraea japonica‘Gold Mound’>Lespedeza bicolor>Ligustrum quihoui>Cornus alba>Forsythia mandschurica>Syringa microphylla.The purification effect on COD was as follows,Spiraea japonica‘Gold Mound’>Cornus alba>Syringa microphylla>Amorpha fruticosa>Lespedeza bicolor>Ligustrum quihoui>Forsythia mandschurica.The purification rate showed a trend of decreasing first and then stabilizing with the extension of growth time.
