双极膜电渗析技术在工业高含盐废水中的应用
Application of bipolar membrane electrodialysis for industrial high-salinity brine valorization
摘要
Abstract
Bipolar membrane electrodialysis(BMED)as an advanced separation tool can effectively generate acid and base from its corresponding salts, respectively. Currently, the application of BMED for valorization of industrial high-salinity brine becomes a hot topic due to its technological superiority. However, some difficulties restrict its real practical application. In this paper, we comprehensively reviewed the application status of BMED for industrial high-salinity brine valorization in recent years and systematically discussed three critical barriers including the technical barrier associated to acid-base concentration and purity, techno-economic barrier related to process cost and economic barrier for investment cost, which hindered the large-scale industrial application of BMED technology. In view of these barriers, the further research and development of BMED technology is suggested which should focus on the reduction of bipolar membrane cost and elimination of co-ion leakage and water migration through ion exchange membrane. Presently, the reuse of prepared acid and base solution in the system process is strong recommended due to low acid-base quality as commercial product. Furthermore, this reuse process can decrease the expense of acid-base outsourcing so as to create extra economic benefit to offset the high investment cost of BMED technology.关键词
