摘　　要：EGSB(Expanded Granular Sludge Bed,膨胀颗粒污泥床)厌氧反应器虽处理能力大、效率高、抗冲击能力强,但启动较困难,若操作不当,易发生酸化现象,致使启动失败。特别是采用絮状污泥接种情况下,EGSB启动时间较长。采用城市污水处理厂厌氧消化污泥(絮状)接种,在启动过程中,合理控制升温速度、选择恰当的启动负荷、严格控制出水pH值和挥发酸,避免反应器酸化,可有效缩短EGSB反应器启动时间并取得较好处理效果。EGSB （Expanded Granular Sludge Bed） is an anaerobic reactor and is widely used in highstrength alcohol distillery wastewater treatment due to its high treatment capacity,efficiency,and stability.However,the EGSB reactor often causes much trouble during startup.The improper operation can cause acidification of reactor very easily and then lead to a failure startup.Furthermore,EGSB reactor needs a long startup period,especially when sludge flocs is used as a seed during startup.When anaerobic digestion sludge flocs from a municipal wastewater treatment plant is used as a seed,the startup period can be reduced significantly with minimum acidification of reactors and the treatment performance can also be improved by controlling the heating rate,the appropriate start-up loading,effluent pH and volatile acids.
