中文摘要 |
用热带假丝酵母在 1.5L气升式内循环生物反应器中处理啤酒生产中的洗糟废水 ,同时生产热带假丝酵母 .探讨了 pH,温度及氮源对降解废水动力学的影响 .实验结果表明 ,用热带假丝酵母既可以有效地降解洗糟废水中的 COD,又可以产生一定数量可作单细胞蛋白的酵母 .对于含糖 0.3%左右的洗糟废水可获得约 500 mg/L(干重 )的酵母 ,并可使废水 COD降解约 80% . |
英文摘要 |
The wastewater from brewery's grains washing procedure was treated in an 1.5L airlift bioreactor for cultivation of Candida tropicalis and simultaneously degradation of COD of the wastewater.Influence of pH,temperature and nitrogen source on the kinetics of wastewater degradation was discussed.The results showed that COD could be degraded efficiently and yeast could be produced at the same time.For the wastewater with 0 3% sccharides,500mg/L yeast (dry) could be obtained and COD could be degraded nearly 80%. |
