摘　　要：采用基于陶瓷平板微滤膜所开发的CMBR工艺对高浓度含油废水进行了可行性处理实验研究。实验中,进水COD从300 mg/L逐步提升至7 500 mg/L,进水油类质量浓度从0 mg/L逐步提升至1 606.5 mg/L,COD有机负荷从0.1 g/(L·d)逐步升至2.03 g/(L·d)。结果表明,控制COD有机负荷在1.5 g/(L·d)时,COD去除率97.4%,油类去除率99.8%,CMBR工艺运行稳定,出水完全能达到GB 8978-1996中一级排放标准所要求值。The feasibility of treating high-concentration oil wastewater in CMBR process which was developed by ceramic MF membrane was studied. In the experiment,the concentration of influent COD was increased from 300 mg/L to 7500 mg/L while the concentration of oil was increased gradually from 0 mg/L to 1606.5 mg/L and COD organic load was from 0.1 g/（L·d） to 2.03 g/（L·d）. The results showed that COD removal rate is 97.4% with oil removal rate up to 99.8% when influent organic load was no more than 1.5 g/（L·d）. It was dedicated that CMBR process operated stably and effluent could totally meet the first class of the national emission standard.
