多年生黑麦草对氨废水净化效果的试验研究

对以植物滤器净化设施养殖废水的研究是一个新兴的领域.研究了采用陆生多年生黑麦草(Lolium perenne L.)滤清4种不同浓度的含氮废水.结果表明在各氨氮(TAN)初始浓度为21.10,49.99,107.46和145.96 mg·L-1,非离子氨(UIA)浓度为14.3,40.1,91.7和125.2 mg·L-1条件下,经过约1 d(22 h)的处理后,4组TAN浓度分别降低:20.94,45.39,49.99和49.3 mg·L-1,UIA下降:14.3,40.1,90.78和103.66 mg·L-1.表明高浓度的UIA对牧草有显著的抑制作用,试验结束时(21d),G1,G2,G3,G4的植株高度分别为32.3,31.3,19.9和17.5 cm,鲜草产量为1.86,1.71,0.49和0.24 kg·m-2,干物质产量为0.21,0.19,0.06和0.04 kg·m-2.
