水栽培蔬菜对养鱼废水的水质净化效果

Effect of hydroponic vegetables on water quality purification of aquaculture waste water

在上海水产大学设施渔业研究所设计的闭合循环水产养殖与蔬菜水栽培综合生产系统中进行暗纹东方养殖和蔬菜水栽培技术研究。水栽培蔬菜对养鱼废水的净化效果表明 ,水栽培蔬菜对氨氮、亚硝氮、硝氮、总氮、磷酸盐和COD的最大去除率分别为 5 7.4 6 %、5 1.72 %、3.7%、10 .6 7%、9.72 %和 2 1.78% ;水栽培蔬菜进水和出水的平均N/P比分别为 6 .6 0 :1和 6 .5 3:1。

Obscure puffer (Fugu obscurus Abe) and hydroponic vegetables were cultured in closed circulation aquaculture and hydroponic economy crop integration production system, designed by, Research Institute of Aquaculture engineering, Shanghai Fisheries University. The results of water quality purification effect of hydroponic vegetables indicate: The hydroponic vegetable's maximal purification rate of ammonia N, nitrite N, nitrate N, total N, phosphate P and COD is 57.46%, 51.72%, 3.7%, 10.67%, 9.72% and 21.78% respectively; Average N/P ratio of inlet and outlet is 6.60∶1 and 6.53∶1 respectively.
