摘　　要：为避免糖蜜酒精废水厌氧处理中硫酸盐还原菌(SRB)对产甲烷菌(MPB)的基质竞争性抑制,并消除硫化物对MPB的毒性作用,在30℃下,利用厌氧折流板反应器(ABR)对糖蜜酒精模拟废水进行了历时92d的启动试验。结果表明,采用低COD和低SO42-负荷启动,是ABR反应器成功启动的关键;成功启动后,各隔室出现明显的相分离(产酸还原硫酸盐相和生成硫单质产甲烷相)特征,说明在微氧/厌氧环境中,酸化菌(AB)可与SRB共存,无色硫细菌(CSB)可与MPB共存;在反应器的第4隔室生成大量单质硫颗粒,可以达到回收利用单质硫的目的。可见,采用ABR处理糖蜜酒精废水是完全可行的。In order to avoid substrate-competitive inhibition of sulfate reducing bacteria （SRB） on methane producing bacteria （MPB） in anaerobic treatment of molasses alcohol wastewater and reduce toxicity inhibition of sulfide on MPB, the three-stage start-up experiment for treatment of simulated molasses alcohol wastewater was conducted with an anaerobic baffled reactor （ABR） at 30℃ and lasted 92 days. The results show that low COD and SO4^2- loading are critical to the start-up of ABR. After the successful start-up, a significant separation phenomenon between acidogenic （or sulfate-reducing） phase and meth-anogenic （or sulfur-producing） phase occurs in each compartment, which shows that acidogenie bacteria （AB） can co-exist with SRB, and colorless sulfur bacteria （CSB） can co-exist with MPB in oxygen-limited anaerobic environment. Also, an abundant amount of granular sulfur produced in the fourth compartment of ABR can be reused. The feasibility of treating molasses alcohol wastewater in ABR is evident.
