摘　　要：煤化工行业用水量巨大,废水排放是制约煤化工产业高质量发展的重要瓶颈之一。因此,加强煤化工“零排放”技术,是实现煤化工产业转型和高质量发展的必然要求。多效蒸发技术是一种将多个蒸发器串联起来,通过多效蒸发和冷凝,实现废水中水分和溶质的有效分离的技术。基于此,针对多效蒸发及冷凝技术进行了分析和探讨。The coal chemical industry consumes a huge amount of water,and wastewater discharge is one of the important bottlenecks that restrict the high-quality development of the coal chemical industry.Therefore,strengthening the"zero emission"technology of coal chemical industry is an inevitable requirement for achieving the transformation and high-quality development of the coal chemical industry.Multi effect evaporation technology is a technique that connects multiple evaporators in series and achieves effective separation of water and solutes in wastewater through multiple evaporation and condensation.The article analyzes and explores this.
