摘 要：
采用室内养殖方法,进行了利用NFT培多花黑麦草(LoliummultiflorumLam)净化尼罗罗非鱼(Oreochromisniloti-cus)养殖废水并回流循环利用的研究。为期30d的试验表明,(1)养殖池水质参数除TP(总磷)超标外,其余指标均满足淡水渔业水质标准;(2)草生长增加的净化能力不足以净化鱼生长增加的污染物,水质总体上呈现恶化趋势;(3)NFT培多花黑麦草的生物量和品质与土培多花黑麦草基本一致;(4)仅利用多花黑麦草净化废水不能实现高密度养殖,必须采用其它措施。

摘 要：
Recirculated wastewater froma tilapia(Oreochromis niloticus)culture tank was treated by Loliummu ltiflorumLamof NFT culture and reused.The 30days' results indicated that the water quality in the fish pond conformed to the requirements of Fishery Water Quality Standard(China)except for TP and tended to deteriora te because the increase of cleaning a bility fromthe grass growth was not sufficient to absorb polluta nts increased by the improved biomass of fish.The biomass and chemical components of Lolium multiflorum Lam by NFT culture were s imilar to those by soil culture.Inte nsive culture of fish could not succeed from cleaning wastewater only through Lolium multiflorum Lam culturing until other ap proaches were applied at the same tim e.
