采用两相厌氧—好氧工艺,在厌氧接触池投入塑料环,后接自行研究开发的厌氧挡板反应器(内设20μm沸石载体),再接SBR反应池处理白酒淘洗生产废水。重点介绍了废水处理工程的设计特点和运行效果。运行结果表明了处理效果十分稳定,进水COD_Cr在3000mg/L左右,出水均在100mg/L以下,并对调试运行中出现的问题进行了讨论。

Two phase anaerobic- aerobic process is invest igated for the t reatment of w hite w ine w astewater.T he anaerobic contact pond of this process is packed w ith plast ic ring, then a SBR pond anaerobic baff le reactor fo-l lows.The present study focuses on the desig n feature and operat ing result s of wastewater treatment.The operating result s show that the t reatment ef fect is fair and stable.The inlet COD_Cr is around 3 000 mg/ L, and that for the ef fluent is lower than 100 mg/ L, and the problem in operat ion is summarized.
