摘　　要：采用2株分离自海南海域的微藻——双眉藻(Amphora sp.BQW)和等鞭金藻(Isochrysis sp.HN)分别处理幼虾养殖废水。结果表明,双眉藻和等鞭金藻均能在幼虾养殖废水中生长,相对生长速率分别是0.168和0.05。培养8 d后,等鞭金藻和双眉藻对幼虾养殖废水总磷的去除率分别达到30.9%和70.9%,总氮的去除率分别为1.0%和28.7%,硝酸盐氮的去除率分别达到了72.0%和85.7%,亚硝酸盐氮无显著差异,而氨氮含量则显著升高。Two microalgae,Isochrysis sp.HN and Amphora sp.BQW,were isolated from coastal seawater in Hainan and cultured with juvenile shrimp aquaculture wastewater.Results showed that both strains grew well in shrimp breeding wastewater.The relative growth rate of Amphora sp.BQW cultured in shrimp breeding wastewater was 3.53 times higher than that of Isochrysis sp.HN.After 8 days of culture,Isochrysis sp.HN and Amphora sp.BQW removed the total phosphorus in the waste water by 30.9％ and 70.9％,the total nitrogen by 1.0 ％ and 28.7％ and the nitrate nitrogen by 72.0 ％ and 85.7％,respectively.However,nitrite nitrogen concentration in the wastewater was not significantly removed after the waste water was treated with the microalgae,and the ammonia nitrogen concentration in the waste water increased obviously after the treatment.
