摘要:
采用无机陶瓷微滤膜提纯凹凸棒石粘土,考察了陶瓷膜孔径、操作条件和料液性质对微滤过程的影响。实验结果表明,不同的膜孔径,微滤通量和截留率不同,采用孔径为0.2 μm的陶瓷膜,渗透通量为48.5 L/(m2·h),截留率超过99%。确定了合适的实验过程工艺参数:操作压力0.12 MPa; 膜面流速1 m/s; 凹土料液浓度20 g/L; 料液温度323 K; pH值6.0。
Abstract:
The microfiltration separation process of attapulgite clay was studied with inorganic ceramic membrane. The influence of operation parameters, including membrane pore size, operation condition(pressure and temperature), and the solution properties of the permeation flux and retention rate were studied respectively. The results showed that permeation flux and retention rate were different for different membrane pore size. The permeation flux was 48.5 L/(m2·h)and retention rate was above 99% when the pore size of membrane was 0.2 μm. The optimum parameters obtained include operating pressure 0.12 MPa, operating temperature 323 K, cross-flow velocity flux 1.0 m/s, mass concentration of the suspension 20 g /L and pH 6.0.
