摘要：制盐废液(苦卤)资源化利用是实现盐化工行业可持续发展的关键。系统总结了苦卤资源化利用的主要技术路线,包括膜分离、化学沉淀、离子交换等,深入分析了各种技术的基本原理、工艺特点和应用前景。在此基础上,重点探讨了苦卤资源化利用在提取锂、镁、钾、硼等有价元素,以及废水处理、CO_(2)吸收等领域的应用潜力。针对苦卤资源化利用面临的技术瓶颈和挑战,提出了一系列前瞻性的对策建议,包括开发膜法与化学法耦合的新型分离技术、研制高选择性离子交换和螯合材料、优化蒸发结晶工艺等,以期实现苦卤资源的高效利用和废液的近零排放,推动盐化工行业的绿色转型和可持续发展,对于指导制盐废液的资源化利用实践具有重要的理论意义和应用价值。
The resource utilization of salt-making wastewater(bittern)is crucial for the sustainable development of the salt-making industry.This paper systematically summarizes the main technical routes for bittern resource utiliza-tion,including membrane separation,chemical precipitation and ion exchange.The basic principles,process charac-teristics,and application prospects of each technology are thoroughly analyzed.On this basis,the article focuses on the application potential of bittern resource utilization in extracting valuable elements such as lithium,magnesium,potassium,and boron,as well as in wastewater treatment and CO_(2) absorption.To address the technical bottlenecks and challenges in bittern resource utilization,this paper proposes a series of forward-looking countermeasures and suggestions,including of developing novel separation technologies that coupled with membrane and chemical meth-ods,designing highly selective ion exchange and chelating materials,and optimizing evaporation crystallization pro-cesses.The aim is to achieve efficient utilization of bittern resources and near-zero discharge of wastewater,and to promote the green transformation and sustainable development of the salt-making industry.This article holds signifi-cant theoretical and practical value for guiding the resource utilization of salt-making wastewater.
