摘　　要：基于黄姜废水处理工程运行实际,着重分析了pH值、温度、COD及容积负荷等因素对UASB反应器启动的影响。该工程利用预处理+厌氧+好氧+混凝、脱色组合工艺处理黄姜废水,在进水COD和色度分别达12000mg/L和600倍的情况下,出水COD和色度分别为110mg/L和50倍,COD去除率达99%。废水经处理后出水水质符合《皂素工业水污染排放标准》(GB20425-2006)。Based on the process of turmeric wastewater treatment,influence factors including pH value,temperature,COD and volume load to the start-up stage of UASB reactor were analyzed.The sapogenin wastewater was treated by adopting the technology of Pretreatment ＋ aerobic digestion ＋ coagulating sedimentation and oxidation decolor.The results showed that the COD fell from 12 000 mg/L to 600 and the chromaticity from 110 mg/L to 50.COD removal rate could reached 99%。Treated wastewater effluent quality accord with the national ＂saponin industrial water pollution discharge standards＂（GB20425-2006）.
