摘　　要：采用UASB厌氧反应器处理木薯酒精废水,实验运行周期为62d.在室温条件下,进水COD浓度逐渐从5 129mg/L提高到28 920mg/L.实验过程中COD去除率最高达95.9%,沼气中的甲烷含量最高达到73%,池容产气率最高达4.6m3/(m3·d),反应器运行良好.UASB厌氧反应器处理木薯酒精废水的效果显著.实验对UASB反应器的工艺参数进行了研究,为规模化、工程化处理高浓度木薯酒精废水提供参考.The cassava alcohol wastewater was treated with UASB anaerobic reactor. The experimen tal operation period was 62 days. At room temperature,the influent COD concentration gradually in creased from 5 129 mg/L to 28 920 mg/L. During the experiment,the COD removal rate was up to 95.9%,the methane content in biogas was up to 73%, the volume gas productivity was up to 4.6 m^3/（m^3·d）,the reactor was running well. The effect of UASB reactor on the treatment of cassa va alcohol wastewater was significant. The experimental parameters of the UASB reactor were stud led,which provided a reference for the large scale and engineering treatment of high concentration cas sava alcohol wastewater.
