水解酸化-改良UASB最佳运行参数研究
Study on the Optimum Operating Parameters of Hydrolysis Acidified and Improved UASB
摘要
Abstract
The technical parameters of treating corn alcohol wastewater by the hydrolysis acidified and improved UASB were studied to provide references for the wastewater treatment of alcohol production industry. The optimum operating parameters of the most representative hydrolysis acidified and improved UASB reactor were determined. The results showed that the best single factor conditions were: influent pH of 5. 5 -7.0 and 15 L/h flow rate, under such conditions, the removal rate of COD could reach to 45% and the concentration of NH3-N increased; when influent pH was 6.0, the time of hydraulic retention was 24 hours, the speed of ascent was 0.4 m/h in the improved UASB reactor, the effluent COD was stable around 450 mg/L, and the average removal rate was 81. 82% , the average removal rate of COD by the hydrolysis acidi-fied-improved UASB reactor was 87.52% , and could reach the maximum of 92.72%. The processing parameters mentioned above could be used for the waste water treatment in the alcohol processing industry, which could promote the water quality of effluent, and was advantageous to the follow-up treating unit of alcohol wastewater.关键词
