摘　　要：为解决稠油污水膜法资源化的预处理问题,采用无机碳膜处理油田生化出水。研究了跨膜压差和温度对膜通量大小以及膜通量稳定性的影响。研究表明:经40nm无机碳膜处理后SDI小于3,悬浮物含量小于0.1mg/L,浊度小于0.1NTU,满足反渗透进水要求;最佳工艺条件为跨膜压差0.3MPa,温度区间36℃～40℃。Carbon inorganic membrane was adopted for the treatment of the oilfield biochemical sewage to solve the problem of pretreatment on heavy oil sewage.Effect of ΔTMP and temperature on the magnitude and stability of membrane flux was studied.It is found that after being treated with 40 nm carbon inorganic membrane,water quality meets the requirements of inlet water quality for the reverse osmosis membrane,with SDI below 3,the turbidity under 0.1 NTU,and the suspended solids content less than 0.1 mg/L.The optimum processing conditions for the treatment are that the ΔTMP is 0.3 MPa and the temperature ranges from 36℃ to 40℃.
