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。
在漂浮植物脩複繫統中種植直葉生菜對豬場廢水進行淨化試驗。結果錶明:經過28 d種植之後,生菜對供試豬場廢水中總氮、氨氮、總燐、可溶性燐、COD的去除率分彆達51.73%、59.45%、57.52%、41.11%、60.15%,其貢獻量分彆達27.95%、30.08%、21.02%、15.56%、20.64%;在供試廢水中栽培直葉生菜的生物量顯著高于土壤栽培的生物量,而且生產植株體內NO3--N、P、Zn、Cu等含量均顯著低于土培後的生菜。

Lettuce(Sativa L. var. longigolia lam.) has been planted in a floating phytoremediation system for the de-contamination 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 contribu-tion 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.
