摘要
采用0.2μm无机陶瓷膜精滤工业碳酸钠溶液.并对精滤前后的碳酸钠溶液的清澈度,有价金属杂质离子含量等进行了对比分析.试验表明,精滤后的碳酸钠溶液清晰、透明,有价金属杂质离子含量降低,精滤后的碳酸钠溶液物理和化学指标接近或达到分析纯要求.采用陶瓷膜精滤工业碳酸钠溶液,能够保持较高的通量,而且受污染的膜经过清洗和再生,通量可以恢复,能满足工业生产的要求.
Filtration of industrial sodium carbonate solution was carried out using inorganic ceramic membrane with pore size of 0.2 μm. The experimental results show that the permeate was clear, and the content of metal ion was decreased. The membrane flux was increased and stable. Ceramic membrane flux can be recovered by chemical cleaning. In the experiment, the concentration of sodium carbonate solution can not affect obviously ceramic membrane flux. The result shows that the ceramic membrane technology used to treatment the industrial sodium carbonate solution was reasonable, and can be used in the industrial application.
