摘　　要：利用螺旋藻、由真菌和螺旋藻组成的菌-藻共生系统处理啤酒废水,旨在为啤酒废水的资源化利用提供一条可行的途径。由螺旋藻和真菌形成的菌丝球组成菌-藻共生系统处理啤酒废水,与螺旋藻单独处理废水作对比,比较两者的废水净化效果以及螺旋藻的生长情况。从2组实验对比情况来看,菌-藻共生系统对啤酒废水的处理效果更好。螺旋藻和菌-藻共生系统对啤酒废水中几种主要污染物的去除率分别为:COD 70.59%和77.81%,TN 70.17%和84.28%,TP37.99%和50.88%。螺旋藻在废水中生长积累的蛋白质含量最高可达49.71%,明显高于在Zarrouk培养基中的螺旋藻蛋白含量(38.57%)。研究结果表明,螺旋藻及菌-藻共生系统对啤酒废水有较好的净化作用,所得螺旋藻生物质可用于加工饲料、饵料、色素的提取等。In order to find a feasible way for brewery wastewater utilization, free Spirulina and a fungi-Spir- ulina symbiosis system were developed for brewery wastewater treatment. Wastewater purification effect and Spir- ulina growth were investigated in two wastewater treatment systems, respectively. It showed that fungi-Spirulina symbiosis system had a better wastewater treatment effect through the comparison of two groups of experiments. The removal efficiency of free Splrulina on total nitrogen, total phosphorus and COD were 70. 17% , 37.99% and 70.59% , and the fungi-Spirulina symbiosis system, 84.28% , 50.88% and 77.81% , respectively. Spirul- ina grow in wastewater accumulated more protein than in Zarrouk medium, the protein content can reach up to 49.71% of dry biomass. The results show that free Spirulina and fungi-Spirulina symbiosis system both have good purification effect of brewery wastewater and the Spirulina biomass can be used for feed processing, bait and extracting pigments after purification.
