两级UASB+A/O处理红薯湿淀粉废水

Application of Two-stage UASB and A/O Process for Sweet Potato Wet Starch Wastewater Treatment

介绍了采用两级UASB+A/O工艺处理红薯湿淀粉废水的工程实例。该工艺具有很好的耐冲击负荷能力,对波动性较大的工业废水处理尤为适合。结果表明,该工艺运行稳定,出水COD≤93 mg/L、NH_3-N≤7 mg/L,出水水质达到《淀粉工业水污染物排放标准》(GB 25461—2010)。

The application of two-stage UASB and A/O process for sweet potato wet starch treat- ment is introduced. The process has goodshock loading resistibility and is particularly suitable for fluctua- ting industrial wastewater. It is indicated that the system can run steadily with effluent COD no more than 93 mg/L and effluent NH3 -N no more than 7 mg/L, which meet the Discharge Standard of Pollutants for Starch Industry（ GB 25461 - 2010）.
