研究了以猪粪废水培养一株三角褐指藻（ Phaeodactylum tricornutum）的可行性．结果表明：猪粪废水经30 g／L盐水适当稀释后可直接用于三角褐指藻的培养，无需添加其他营养物质．在污水稀释率为25倍时，藻细胞可良好地生长，最高密度为合成培养基的1．52倍．同时三角褐指藻有效去除了污水中的氮磷，总氮、氨氮和总磷的去除率分别为23％，93％和93％．与合成培养基养殖的藻相比，猪粪废水养殖的三角褐指藻的二十碳五烯酸和多不饱和脂肪酸的含量略有上升，实现了培养三角褐指藻转化废水为生物量并积累多不饱和脂肪酸的资源化．

The feasibility of using the diluted piggery wastewater as nutrient supplement to culture Phaeodactylum tricornutum was investigated.The results showed P.tricornutum could be cultivated in the piggery wastewater diluted with 30 g/L salt water, without other nutrition ingredients.When the piggery wastewater was diluted 25 times, P.tricornutum grew well and the maximum cell density was 1.52 times that of the synthetic medium.Meanwhile, nitrogen and phosphor were removed efficiently.The removal rate of total nitrogen, ammonia nitrogen and total phosphorus was 23%,93%和93%respectively.The contents of eicosapentaenoic acid and polyunsaturated fatty acid of P.tricornutum cultivated in piggery wastewater were a little more than that of P.tricornutum cultivated in synthetic medium.Recycling of piggery wastewater for the accumulation of biomass and polyunsaturated fatty acids was therefore realized by the cultivation of P.tricornutum.
