新型人工湿地对磷的去除特征研究

Study on Phosphorus Removal Feature in New Constructed Wetland

人工湿地因其治理污染方面的诸多优势,为各国政府所重视。本研究通过设计6种新型人工湿地组合床试验,得出组合床对TP的去除率由大到小:再力花组合床>鸢尾组合床>鸢尾浮床组合床>菖蒲组合床>空白床>茭白组合床>美人蕉组合床;DIP去除率:再力花组合床>菖蒲组合床>鸢尾组合床>鸢尾浮床组合床>空白床>茭白组合床>美人蕉组合床。组合床对两种形态磷的去除率无明显的相关性。人工湿地去除磷污染相关研究中结合基质、水污染浓度和植物,特别是在植物选择中结合植物组织结构类型综合考虑组合达到最佳效果。

Because of its advantages in pollution control, the new constructed wetland had received great deal of attention from the governments all over the world. Phosphorus removal was studied in this paper by designing six compound beds of new artificial wetland. The total phosphorous removal efficiency of compound beds in descending order was ： another force flower combination bed 〉 iris flower combination bed 〉 iris floating bed combination bed 〉 calamus combination bed 〉 blank bed 〉 water bamboo blank bed 〉 canna combination bed ; DIP removal rate was： another force flower combination bed 〉 calamus combination bed 〉 iris flower combination bed 〉 iris floating bed combination bed 〉 blank bed 〉 water bamboo blank bed 〉 canna combination bed. The ccombination beds have no significant correlation for the two different kinds of phosphorus rates. The study related artificial wetland remove phosphorus pollution combining matrix, water pollution concentration and plants, especially in plants in the choice of combination of plant tissue structure types of comprehensive consideration of the combination to achieve the best effect.
