水解酸化-改良UASB工艺处理玉米酒精废水
Treatment of corn alcohol wastewater using hydrolysis acidification-improved UASB
摘要
Abstract
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.关键词
