采用厌氧UASB-好氧接触氧化工艺对汽车脱脂废水进行连续处理实验研究.结果表明,在脱脂废水进水COD浓度为6 000 mg/L,厌氧水力停留时间为3.4 d,好氧水力停留时间为2.5 d条件下,COD总去除率平均为93%,厌氧段平均值为38%.厌氧段可以提高出水的可生化性,厌氧-好氧接触氧化工艺效果要明显优于好氧工艺.

In order to promote the removal rate of COD of automobile degreased waste water,anaerobic-aer-obic process was employed.When the influent COD concentration was 6 000 mg/L,HRT was 3.4 d in the anaerobic reactor and 2.5 d in the aerobic reactor,the average COD removal rate was 93%.The results show that the anaerobic reactor can improve the biodegradability of the effluent,the effect of anaerobic-aerobic process is better than aerobic process.
