选用型号为NFW的纳滤膜处理维生素C(简称维C)废水,进水COD、TOC平均浓度和电导率分别为160 mg/L、18.21 mg/L和18.62 mS/cm,COD和TOC去除率为93.75％和95.67％,脱盐率为38.01％.采用响应面法分析了膜运行主要操作条件(操作压力P;温度T;进水流量Q)与膜污染评价指标(膜通量和污染指数)的关联性并建立了拟合方程,在此基础上获得了最优操作条件.结果表明:关于膜通量和污染指数的二次拟合方程,决定系数(R2)分别是97.53％和90.04％,拟合结果良好.该拟合方程获得的纳滤膜处理维C废水的最优操作条件为:压力P=966 kPa,温度T=24℃,进水流量Q=456 L/h.实验验证结果表明,上述最优操作条件结果可靠.
