| 摘 要： | 以膜-生物反应器(MBR)为预处理工艺,构建了MBR-纳滤组合系统并应用于生活污水和大型超市废水的处理,考察MBR作为纳滤预处理的可行性,评价纳滤膜的出水水质,分析不同操作模式和不同进水水质对纳滤膜的渗透性能的影响。研究表明,MBR作为纳滤的预处理是完全可行的。MBR-纳滤组合工艺处理生活污水的出水平均值:浊度0.09～0.44 NTU,电导率553.7～902.3μS/cm,TOC 1.75～5.57 mg/L,TN 1 1.3～12.5 mg/L,TP0.2 mg/L;MBR-纳滤组合工艺处理超市废水的出水平均值:浊度0.075～0.26 NTU,电导率143.2～388.9μS/cm,TOC 2.71～5.03 mg/L,TN为1.6～3.3 mg/L,TP0.2 mg/L。纳滤系统的出水水质低于城市生活饮用水标准中绝大多数常规检测项目中所规定的限值,也可满足循环冷却水用再生水水质标准。
