| 摘 要： | 目的]研究啤酒废水培养螺旋藻的可行性。方法]利用啤酒废水培养螺旋藻，研究不同废水浓度下螺旋藻的生长状况及其对废水中氮、磷、有机质的去除效率，以及在放大培养时螺旋藻的生物量、蛋白质和脂肪舍量。结果]螺旋藻可在啤酒废水中生存，且啤酒废水有缓冲培养液pH增加的作用，能使螺旋藻更长时间处于适宜生存的状态。50％啤酒废水、50％Zarrouk培养液最适宜螺旋藻生长，且产量达到最大。同时，螺旋藻可对啤酒废水产生净化作用。螺旋藻对100％啤酒废水中有机质、总氮、总磷的去除效率分别可迭55．95％、77．78％和42．62％。在最佳配比浓度条件下，放大培养的产藻量为0．794g/L，蛋白质和脂肪含量分别达到69．5％和8．11％。结论]该研究可使污水净化和螺旋藻利用相结合，达到环境与经济效益的统一。

| Abstract: | Objective ] The research aimed to study the feasibility of Spirulina cultivation with beer wastewater. Method ] By using beer wastewater to cultivate Spirulina, growth condition of the Spirulina under different wastewater concentrations, its removal efficiencies on nitrogen, phosphorus and organic matter in wastewater, biomass, protein and fat contents of Spirulina at enlarged cultivation were studied. Result] Spiruli- na could survive in beer wastewater. Beer wastewater played the role of buffering pH increase of culture solution, making that Spirulina was at the suitable survival state for long time. 50% of beer wastewater and 50% Zarrouk culture solution was the most suitable for the growth of Spirulina, and the yield reached the maximum. Meanwhile, Spirulina could purify beer wastewater. For 100% of beer wastewater, removal rates of the organ- ic matter, total nitrogen and total phosphorous respectively reached 55.95%, 77.78% and 42.62%. Under the optimal concentration ratio, Spir- ulina yield was 0. 794 g/L, and protein and fat contents respectively reached 69.5% and 8.11%. Conclusion ] The research could combine sewage purification with Spirulina usage to reach the unity of environmental and economic benefits. |
