摘　　要：在医药制造业中,乙醇作为一种关键的溶剂,在生产过程中广泛应用,其后处理会生成大量的含乙醇废水,若不经处理直接排放,将对环境造成严重污染[1]。通过回收纯化乙醇,不仅可以显著减少废水排放,也能有效降低药用乙醇的购买成本,从而具备了经济和环保双重效益。研究聚焦于在药品生产中乙醇醇沉步骤后,如何有效去除乙醇中的杂质。通过对人员、物料、机器、操作方法、环境和检测等方面进行分析,研究结果表明:采用不同的控制方法,如:采用动态累积间歇乙醇回收塔装置、分子筛吸附技术、膜分离技术等方法,最终达到符合要求的药用乙醇。In the pharmaceutical manufacturing industry,ethanol serves as a crucial solvent and is widely used in production process-es,generating a large amount of ethanol-containing wastewater during post-treatment.Direct discharge of this wastewater without treatment would cause severe environmental pollution[1].By recovering and purifying ethanol,not only can wastewater discharge be significantly reduced,but the pur-chase cost of pharmaceutical-grade ethanol can also be effectively lowered,thereby yielding both economic and environmental benefits.Focusing on how to effectively remove impurities from ethanol after the ethanol precipitation step in drug production,through analysis of personnel,materials,machinery,operating methods,environment,and testing,the research results indicate that the adoption of various control methods,such as the use of dynamic cumulative batch ethanol recovery tower units,molecular sieve adsorption technology,membrane separation technology,and other meth-ods,ultimately achieves pharmaceutical-grade ethanol that meets requirements.
