【摘要】 在全球能源危机加剧和气候变暖的背景下，针对淡水资源短缺危机问题，提出了热膜耦合海水淡化系统。建立了反渗透（RO）和多效蒸馏（MED）海水淡化数学和经济建模，基于能量流和物质流，提出了4种不同的耦合工艺方案，通过冬季和夏季两工况分别优化了各工艺方案。综合分析各耦合工艺方案，冬季工况下，方案三中RO与MED产水比为8∶2时，经济性最佳，产水成本为0.81 USD·m^-3，相比独立的RO和MED产水分别降低了26.3%和13.8%。同时该工艺具有较高的淡水回收率，回收率高达65.4%。研究的热膜耦合工艺可与可再生能源进行耦合获得更好的经济效益和社会效益。更多还原

【Abstract】 In the context of the escalating global energy crisis and climate change,addressing the crisis of freshwater scarcity,a hybrid thermal-membrane desalination system was proposed.Mathematical and economic modeling of reverse osmosis （RO） and multi-effect distillation （MED） seawater desalination was established,and four different coupling process schemes were presented based on energy and material flows.The various coupling process schemes were optimized under winter and summer operating conditions.Comprehensive analysis of the coupling process schemes revealed that under winter conditions,scheme three with an RO to MED water production ratio of 8∶2 was the most economically viable,with a water production cost of 0.81 USD·m^-3,leading to reductions of 26.3%and13.8%in water production costs compared to standalone RO and MED processes,respectively.Additionally,the process exhibited a high freshwater recovery rate,reaching 65.4%.The hybrid thermal-membrane desalination system process studied can be further integrated with renewable energy sources to achieve improved economic and societal benefits.更多还原
