摘　　要：对水生植物凤眼莲、草芦、香蒲、菹草、浮萍等对氧化塘的NH3-N,COD和总磷及重金属的去除能力进行了测定,结果证明:草芦去NH3-N最高达93.6%,凤眼莲去COD最高达63.82%,菹草去总磷高达96.0%,凤眼莲根富集能力很强,其中对Cu富集倍数为886,Cd富集倍数为175,Cr6+富集倍数为2046,其中浮萍对Pb吸附最强,吸富倍数为858.The NH3-N,COD and total P removed by using aquaticplants in lagoons,changzhi,Shanxi were Studied.The results showed that the removed rates of NH3-N,COD and total P were 93.6%,63.82% and 96.0% for Eichhornia crassipes,Phragemites arundinacea,Typha angnsifolia and Lemna minor,respectively.The highest biorichment for the havery metal was Eichhorhia crossipes roots.The rates of biorichment for Cu,Cd and Cr6+ were 886,125,2046 repectively,while the rate of biorichment for Pb was 858 in Lemna minor.
