Abstract:

An UASB （upflow anaerobic sludge bed） reactor has been used for treating the highly concentrated saponin wastewater. The experimental results show that the COD removal efficiency can be over 90% as the reactor temperature is 35-40 ℃， pH is between 6.8 and 7.5， and the COD loading rate remains at 6.0 kg/（m³·d）.

Key words: saponin wastewater, upflow anaerobic sludge bed, anaerobic biological treatment

摘要：

采用UASB厌氧反应器处理高浓度皂素废水,试验结果表明,当温度控制在35～40℃、pH在6.8～7.5之间、COD容积负荷保持在6.0kg/(m3.d)时,COD去除率可达到90%以上。
