摘　　要：采用中温厌氧UASB反应器对汽车脱脂废液进行预处理,在去除COD的同时,还能够提高废液的可生化性。结果表明,在废水与淘米水相混合的情况下,脱脂废液质量浓度达到6g·L-1左右,通过无机酸调节进水碱度为3.5g·L-1时,COD的总去除率可达到84%。出水中挥发酸的含量占COD的40%～50%,有利于后续好氧反应的进行。Thermophilic anaerobic UASB process was used for the pretreatment of automobile degreased wastewater.Besides the removal of COD,improve the biodegradability of effluent.Take the degreased wastewater with rice-washed water together,the concentration of degreased wastewater was about 6 g·L^-1,influent alkalinity concentration was 3.5 g·L^-1,the total removal of COD was up to 84%,VFA in the effluent was 40%～50% of COD,it＇s propitious for the continuous aerobic process.
