Study on anaerobic-aerobic treatment of automobile degreased wastewater
厌氧-好氧接触氧化处理汽车脱脂废水研究

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.
