摘　　要：文章介绍了采用高负荷UASB工艺处理L-乳酸废水的实验装置以及实验过程,分析了UASB有机负荷对CODcr去除率影响以及进出水CODCr的变化,并确定了UASB的产沼气率。研究表明,在中温(37±1℃)环境下,UASB有机负荷在6.5 kg CODCr·m-3·d-1左右时,CODCr去除率在80%左右,运行稳定。The experimental equipment and the process of the Up-flow Anaerobic Sludge Bed technology were introduced to treat Lactic acid wastewater. The affection of anaerobic organic loading to CODcr removal rate and the CODcr variety of the influent and the effluent were analyzed, and the biogas production rate was confirmed. The results showed the CODcr removal rate of UASB remained 80 % and ran steadily at the temperature of 37±1℃ and the organic loading of 6.5kg CODcr·m^3·d^-1 .
