摘要： 以水生植物-梭鱼草作为湿地植物，新型填料蜂巢石作为湿地填料，构建了同时具有美化景观与净化黑臭水体的垂直流人工湿地，并将其成功应用于黑臭水体除磷的中试研究.试验结果表明，人工湿地的TP去除率为58.13%~83.25%，且TP去除率的变化趋势与气温变化趋势相一致.TP的去除效果具有一定的时空变化规律，在运行时间小于2个月时，蜂巢石表层20 cm表现出较其它深度更强的除磷效果；运行时间大于2个月时，不同深度蜂巢石的除磷能力差异不大.利用SPSS V13.0分析5个月中蜂巢石20 cm深度处三价铁与磷含量的相关性，得到皮尔森相关系数 r =-0.692， P =0.018<0.05，表明三价铁含量与磷的含量呈现显著负相关性.

Abstract: Aquatic plants ( Pontederia cordata ) and packing material (pumice) were chosen to construct vertical flow constructed wetlands (VFCW) which have functions of both landscaping and purification of malodorous water body. The pilot study on phosphorus removal from malodorous water body by pumice VFCW was conducted successfully. The concentration of total phosphorus (TP) in influent and effluent of VFCW were detected at different times. The results show that removal rate of TP ranged 58.13%~83.25% and the changing trend of TP removal rate is in accordance with that of temperature. The TP removal effect varies with time and space: In case of short experimental runs (less than 2 months), the surface (less than 20 cm thick) of pumice displays stronger removal effect of phosphorus than other depths; in case of more than 2 months, the removal effects of phosphorus have small variations in different depths. Study on the correlation between ferric iron and phosphorus in the depth of 20 cm by SPSS V13.0 shows Pearson correlation coefficient r =-0.692, P =0.018<0.05, which indicates a negative correlation between the concentrations of ferric iron and the phosphorus.
