摘　　要： 针对微生物烟气脱硫工艺的工业应用问题,设计了容积为96L的上流式厌氧污泥床反应器并用于烟气预处理废水的生物还原。用硫酸盐溶液模拟废水,葡萄糖作为硫酸盐还原菌的碳源,在pH=6.0的条件下启动反应器。在反应器内形成成熟颗粒污泥的基础上考察了水力停留时间、进水负荷波动和设备应急停运对反应器性能的影响。结果表明:接种厌氧污泥30 d即成功启动反应器,在加入厌氧污泥后获得了成熟的颗粒污泥;适宜停留时间为12 h;反应器停运20 d,经7 d再次启动成功。该工艺可满足生产中进水浓度波动或间歇性的处理需求。 Aiming at the industrial application problems of biological flue gas desulphurization process,a 96L up-flow anaerobic sludge blanket reactor is designed for the biological reduction of flue gas pre-treatment wastewater.Sulfate solution is prepared as simulated wastewater and glucose is added as a carbon source of sulfate reduction bacteria.The reactor starts up at pH=6.0.After the mature granular sludge is formed,the effects of different hydraulic retention time（HRT）,changeable loading capacity of influent and emergency shutdown on operation performance of the reactor are discussed.The results show：the reactor starts up successfully in 30 days and the mature granular sludge is obtained after the anaerobic sludge is added;the optimal HRT is 12 hours;after a shutdown of 20 days,the reactor is recovered and restarts up in 7 days.The process can meet the demand of intermittent operation and fluctuating concentration of influent wastewater.
