摘　　要：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 perenneL.)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.Study on aquaculture wastewater treatment with botanical filters is a burgeoning field. Twelve botanical filters with 0.8 m^2 ryegrass （Lolium perenne L. ） were used to treat ammonia wastewater of 4 different concentration levels, The initial total ammonia nitrogen （TAN） concentration of wastewater were 21. 10, 49.99, 107, 46 and 145.96 mg·L^-1 , with the amounts of un-ionized ammonia （UIA） corresponded to 14.3, 40. 1, 91.7 and 125.2 mg·L^-1, respectively. After about one-day （22 h） treatment, results showed that TAN concentrations declined by 20.94, 45.39, 49.99, and 49.3 mg·L^-1 , and UIA declined by 14.3, 40.1, 90.78, and 103.66 mg·L^-1. It was also found that the UIA concentration had a significant effect on the growth of grass. At the end of the trial, the height of grass in group G1, G2, G3 and G4 were 32.28, 31.25, 19.85, and 17.48 cm respectively, with a fresh mass of 1. 86, 1.71, 0.49, and0.24 kg·m^-2, and a dry mass of 0. 21, 0.19, 0.06, and 0.04 kg·m^-2.The research provided foundation for purifying ammonia wastewater with ryegrass.
