摘　　要：采用一种新的工艺技术方法即水解酸化-改良UASB工艺处理玉米酒精废水。结果表明,在改良UASB运行60 d顺利启动完成后,进水COD在5 470～7 910 mg/L之间,TN在70～107 mg/L之间,TP在115～187 mg/L之间,SS在864～1 490 mg/L之间的条件下,水解酸化对COD和SS的去除率分别达50%和51%,NH3-N经过水解酸化后升高。改良UASB对COD的去除率达80%,对NH3-N、TN和TP也有一定去除,去除率分别为12%、17%和20%,经过水解酸化及改良UASB处理利于后续好氧处理。Hydrolysis acidification-improved UASB process was adopted to treat corn alcohol wastewater.The results showed that the removal rates of COD and SS reached 50% and 51%,respectively after the hydrolysis acidification process,when the improved UASB reactor was successfully launched after 60 d operation and the COD,TN,TP and SS concentratinons of the influent water were 5 470~7 910 mg/L,70~107 mg/L,115~187 mg/L and 864~1 490 mg/L,respectively;however,NH3-N concentration increased after hydrolysis acidification.Under the same experimental conditions,the removal rate of COD was up to 80% after improved UASB process,NH3-N,TN and TP were also removed partly,and the corresponding removal rates were 12%,17% and 20%,respectively.Hydrolysis acidification-improved UASB process was beneficial to the subsequent aerobic treatment.
