| 摘要: |
| 为将含高质量浓度铁锰及氨氮的地下水处理成为洁净的饮用水，以哈尔滨市江北某水厂的高铁、高锰、高氨氮地下水(总铁、二价铁、锰及氨氮质量浓度分别为14.67、11.23、0.83和2.22 mg/L)为处理对象，运用接触氧化法-超滤组合工艺对其进行处理，同时考察不同通量条件下超滤膜的污染问题.结果表明，该组合工艺出水水质满足《生活饮用水卫生标准》(GB5749—2006)的要求，且产生高品质出水：总铁、二价铁、锰及氨氮质量浓度平均分别为0.06、0.03、0.04和0.44 mg/L，出水浊度在0.10 NTU以下，对细菌的去除接近100%.扫描电子显微镜-能量弥散X射线谱(SEM-EDS)结果表明，在低通量(20 L/(m2·h))条件下超滤膜污染最轻.

| Abstract: |
| To investigate the operational efficiency of the combined process of contact oxidation and ultrafiltration for the pollutants removal of groundwater, which contained high concentration of Mn(II), Fe(II) and ammonia, a pilot-scale system was conducted and operated in Harbin. Moreover, membrane fouling potential was also investigated under different fluxes. The concentrations of total iron, Fe2+, Mn2+ and NH4+-N in the feed water were approximately 14.67, 11.23, 0.83, and 2.22 mg/L, respectively. Experimental results showed that the effluent water quality of the combined process met Chinese Drinking Water Standard (GB5749—2006), with an average concentration of iron, manganese and ammonia in the effluent of 0.06, 0.04 and 0.44 mg/L, respectively. Furthermore, the turbidity of UF effluent was lower than 0.10 NTU, and with a bacteria removal efficiency of approximately 100%. SEM-EDS results demonstrated a low flux would be beneficial to alleviate the membrane fouling.
