纳滤膜回收离交酸、碱废水技术的研究

Research for technology of Nanofiltration membrane recycling waste water from IX acid-base

介绍了功能糖生产中离交酸碱废水处理过程中存在的问题,通过分段回收酸碱废液,利用纳滤膜分离技术分离纯化酸液、碱液,并优化工艺参数,解决了离子交换脱盐工序酸碱消耗高、产生废液多、运行成本高、污染环境等问题。

Introduce the problem which in the process of deal with the Ion exchange pH wastewater. In the production of the functioanl sugar will generate pH wastewater. Through section recovery the pH wastewater,use the technology of nanofiltration membrance to separate purification acid,lye and optimization of process parameters,solve the problem high consumption of acid base,producing much waste,high operating costs,pulluting the environment in the process of ion exchange desalting.
