摘　　要：在漂浮植物修复系统中种植直叶生菜对猪场废水进行净化试验。结果表明:经过28 d种植之后,生菜对供试猪场废水中总氮、氨氮、总磷、可溶性磷、COD的去除率分别达51.73%、59.45%、57.52%、41.11%、60.15%,其贡献量分别达27.95%、30.08%、21.02%、15.56%、20.64%;在供试废水中栽培直叶生菜的生物量显著高于土壤栽培的生物量,而且生产植株体内NO3--N、P、Zn、Cu等含量均显著低于土培后的生菜。Lettuce（Sativa L.var.longigolia lam.） has been planted in a floating phytoremediation system for the decontamination of piggery wastewater.The results show that after lettuce has been planted for 28 days,the removing rates of total N（TN）,ammonia-nitrogen（NH4＋-N）,nitrate-nitrogen（NO3--N）,total P（TP）,soluble P（SP）,chemical oxygen demand（COD） by the plant are 51.73%,59.45%,57.52%,41.11% and 60.15% respectively,and contribution rates of TN,NH4＋-N,TP,SP and COD are 27.95%,30.08%,21.02%,15.56% and 20.64% respectively.The biomass of lettuce planted in the wastewater for experiments is obviously higher than that of lettuce planted in soils.Furthermore,the contents of NO3--N,P,Zn,Cu,etc.in the body of the plant in the floating phytoremediation system are significantly lower than that in soils.
