以铜钱草（Hydrocotyle vulgaris L.）为试材,在3种浓度梯度的城市生活污水中进行培养,研究了铜钱草对城市生活污水的处理效果.结果表明,铜钱草在3种浓度的城市生活污水中均生长良好,其株高、根长及生物量均有显著增加;铜钱草对高质量浓度（CODCr 287.21 mg/L,TN 14.68 mg/L,TP 3.87 mg/L）、中质量浓度（CODCr 191.62 mg/L,TN 9.69 mg/L,TP 2.74 mg/L）和低质量浓度（CODCr 139.24 mg/L,TN 6.94 mg/L,TP1.46 mg/L）城市生活污水中CODCr的去除率分别为94.99%、84.97%和88.71%;对TN的去除率分别为76.85%、65.24%和57.34%;对TP的去除率分别为92.17%、84.71%和73.24%.表明铜钱草对城市生活污水具有良好的净化效果,可作为城市生活污水治理的优良物种进行推广.
以銅錢草（Hydrocotyle vulgaris L.）為試材,在3種濃度梯度的城市生活汙水中進行培養,研究瞭銅錢草對城市生活汙水的處理效果.結果錶明,銅錢草在3種濃度的城市生活汙水中均生長良好,其株高、根長及生物量均有顯著增加;銅錢草對高質量濃度（CODCr 287.21 mg/L,TN 14.68 mg/L,TP 3.87 mg/L）、中質量濃度（CODCr 191.62 mg/L,TN 9.69 mg/L,TP 2.74 mg/L）和低質量濃度（CODCr 139.24 mg/L,TN 6.94 mg/L,TP1.46 mg/L）城市生活汙水中CODCr的去除率分彆為94.99%、84.97%和88.71%;對TN的去除率分彆為76.85%、65.24%和57.34%;對TP的去除率分彆為92.17%、84.71%和73.24%.錶明銅錢草對城市生活汙水具有良好的淨化效果,可作為城市生活汙水治理的優良物種進行推廣.

Three kinds of ecological floating beds made of Hydrocotyle vulgaris L.were used to study the removal effects on CODCr,nitrogen and phosphorus in municipal domestic wastewater.The experiment was implemented for 32 days.The results indicated that H.vulgaris was adaptable to grow in municipal domestic wastewater of three concentrations,and their biomass,height and root significantly increased at the end of experiment.The removal rates of CODCr in high-concentration,medium-concentration and low-concentration of municipal domestic wastewater were 94.99%,84.97% and 88.71%,respectively;the removal rates of TN were 76.85%,65.24% and 57.34%,respectively;the removal rates of TP were 92.17%,84.71% and 73.24%,respectively.Based on the good purifying effect on CODCr,nitrogen and phosphorus removal,H.vulgaris is recommended as a specie of aquatic vegetation in phytoremediation of municipal domestic wastewater.
