  • 摘要: MBR-NF截留液是一类难处理的高浓度有机废水,其所含有机物几乎都是腐植酸,可考虑资源利用。实验室内采用纳滤对其所含腐植酸进行分离浓缩。引入分离因子来表征纳滤的分离效果。实验结果表明,分离因子(SF)与体积浓缩倍数(CF)有很好的线性关系,浓缩倍数为5时,截留液中有机碳浓度为9 413 mg/L,重金属浓度处于mg/L水平,分离因子达到2.76,表明纳滤可有效地将MBR-NF截留液中的腐植酸与无机盐分离,并进行浓缩。
    Abstract: The retentate from membrane bioreactor (MBR) and nanofiltration (NF) combined process for landfill leachate is difficult to be treated due to high content of refractory organic matter.Since the components of refractory organics in the rtentate are almost humic acids (HA),the laboratory-scale experiments were conducted to investigate separation and thickening of HA from MBR-NF retentate of leachate by NF.Separation factor (SF) was applied to evaluate separation efficiency of NF.The data indicate that SF is strongly correlated with concentration factor (CF).The retentate from NF test performed at CF=5,contains relatively high amount of dissolved organic carbon with a value of 9 413 mg/L and insignificant concentration of heavy metals at the level of mg/L.The SF value is 2.76.These results demonstrate that NF could effectively separate and purify HA in the concentrate from landfill leachate MBR and NF treatment system from inorganic components.
