【摘要】 利用生活污水处理厂氧化沟中的微生物作为菌源,加入糖蜜酒精废液进行微生物驯化,以微生物量、TOC、COD和BOD5为主要指标,研究了不同温度条件对糖蜜酒精废液处理效果及微生物蛋白回收量的影响.结果表明,驯化后所得微生物菌种对糖蜜酒精废液有较强的降解效果,在30℃下反应6 d后,微生物量最高为4.61 g/L,微生物增加量3.71 g/L,COD去除率、BOD5去除率和TOC去除率分别达到48.5%、96.7%和51.9%.本实验为利用糖蜜酒精废液生产微生物蛋白的资源化方法提供了理论和实验依据.更多还原

【Abstract】 The microorganism from oxidation channel as microbe source is domesticated to treat molasses and alcohol wastewater.The biomass,the removal rates of TOC,COD and BOD₅ are used as index to study the influence of temperature on the treatment.The experiment result indicates that the microbes after domesticating can be applied to treat such wastewater with high efficiency.The biomass obtained after 6 days domesticating at 30℃ is measured to be 4.61 g/L with an increase of 3.71 g/L.The removal rates of TOC,COD and BOD₅ are determined to be 48.5%,96.7% and 51.9%.更多还原
