摘　　要：采用颗粒污泥接种UASB厌氧反应器处理木糖醇生产废水，对废水进行预调配后，由电控柜控制间歇进水。试验结果表明：在进水COD为3～5g／L，COD容积负荷在2．70～4．64kg／（m^3·d）的范围时，有机污染物的去除率可稳定地保持在76％～88％，对厌氧出水再进行普通活性污泥法好氧后处理，出水COD可达到100mg／L以下，稳定地达到国家要求的废水一级排放标准。UASB reactor was used to do the treatment of xylitol production wastewater. After pre -treatment of the wastewater, the intermittent flow was controlled by control cabinet. The results revealed that the removal of organic pollutants remained stable at 76% -88% when COD in the influent was about 3 000 -5 000 mg/L and COD load volume was about 2.70 -4.64 kg/（m^3·d）. With an aerobic treatment of the anaerobic effluent, the COD could reach 100 mg/L.
