摘　　要：本文研究了异亮氨基酸生产中发酵废水的厌氧生物处理。在静态试验的基础上用上流式厌氧污泥床反应器（ＵＡＳＢ）进行了动态试验研究，试验结果表明了该发酵废水厌氧生物处理的可行性，ＣＯＤ去除率＞８０％。其工艺条件为：温度３５±１℃，停留时间１０ｈ，最大有机负荷８ｋｇＣＯＤ／（ｍ３·ｄ），沼气产生率６３Ｌ／ｋｇＣＯＤ。Abstract The anaerobic biological treatment of wastewater of fermentation from the process of isoleucine production is studied in this paper.Basted on the static experiment,a dynamic experiment is proceeded with a upflow anaerobic sludge bed (UASB)reactor.The experimental results show that the biological treatment of wastewater of fermentation is feasible and the COD removal efficiency is more than 80%.The Process conditions are that,the temperature is 35±1 degree Celsius,the hydraulic retention time (HRT)is 10h,the greatest organic load is 8kgCOD/m 3·d and the gas produce ratio is 6.3L/kgCOD.
