摘　　要：采用UASB反应器处理1,4-丁二醇生产废水时,分别接种颗粒污泥、絮状污泥及两者的混合污泥,研究不同接种污泥对处理效果的影响。结果表明,接种颗粒污泥的反应器处理效果最好,但接种混合污泥时亦能取得较好的驯化及处理效果;接种颗粒污泥可以提高系统的最大COD容积负荷、抗污染负荷冲击能力及产气量,同时可降低挥发性脂肪酸的积累对微生物活性的抑制;在保持COD去除率>70%的条件下,3组反应器的最大COD容积负荷分别为4.70、3.25和4.50 kg/(m3.d)。Three upflow anaerobic sludge bed （UASB） reactors inoculated with granular sludge,flocculent sludge and a combination of both types of sludge were used for treatment of wastewater from 1,4-butanediol production. The influence of inoculated sludge on the treatment efficiency was investigated. The results showed that the reactor inoculated with granular sludge achieved the highest treatment efficiency. The inoculation of granular sludge could improve the maximum COD volume loading rate, antiload capacity and biogas production as well as reduce inhibition of high VFA to microbial activity. The maximum COD volume loading rates of three reactors were 4.70 kg/（m^3· d）, 3.25 kg/（m^3 · d） and 4.50 kg/（m^3· d） respectively when the COD removal rate was more than 70%.
