摘　　要：以河南某酒精厂的高浓度废水处理工程为对象深入研究厌氧复合床（UBF）反应器的启动过程.废水水质CODcr为12 000~15 000 mg/L;BOD5为6 000~8 000 mg/L;pH3.7~5.0.本次启动研究了反应器内COD去除情况、pH变化、颗粒污泥形成、填料的作用等内容,共历时5个月.启动完成并进入稳定运行期后,出水COD去除率为90%以上、pH值保持在6.6~7.8,并形成沉淀性能良好、具有一定机械强度、粒径为1~4mm的颗粒污泥.To study in-depthly the start-up performance of the full-scale upflow blanket filter（UBF） reactors,an alcoholic wastewater treatment project in Henan is used as research object in this paper.The waste water quality is as follows： CODcr,15000~18000mg/L;BOD5,8000~10000mg/L;and pH 3.5～5.0.The start-up studies the COD removal,PH changes,the formation of granular sludge and the role of filler content,the whole process lasting five months.After the operation of UBF reactor is stable,the removal rate of COD is above 90 %,pH value keeps at 6.5～7.5,and the reactor forms granular sludge（parameter as 1～4 mm） with good settling behavior and mechanical strength.
