摘要
发展燃料乙醇是人类应对石油等化石燃料日渐枯竭及汽车尾气等环境问题的积极举措,也被许多国家视为维系能源战略安全和发展低碳经济的必然选择。因此,全球燃料乙醇产量在过去的几十年中急剧增加。但是,废水处理的问题与此同时也日益加剧,目前已成为阻碍乙醇工业发展的限制因素。为了实现燃料乙醇产业的可持续发展,开发新型的废水处理工艺具有重要意义。国内外研究者开发出了许多乙醇废水处理技术,包括蒸发、回用、单细胞蛋白(Single cell protein,SCP)/生物制品生产、耕地灌溉、厌氧消化和乙醇-沼气双发酵耦联工艺等技术。作者对这些技术进行了系统地总结,阐述了这些技术的原理、特点和优缺点,以期为乙醇废水处理的深入研究提供参考。
Fuel ethanol is developed to resolve the problems of fossil energy draining and vehicle air pollutant. This cleaner fuel is also considered as inevitable choice to keep energy strategy safe and develop low carbon economy. Therefore, worldwide ethanol production has increased sharply fbr last decades. However,wastewater handling problem become increasingly severe at the same time. It is very important to improve the wastewater treatment technology to achieve sustainable development of bioethanol industry. The domestic and foreign researchers developed many ethanol wastewater treatment technologies,like evaporation,reuse,single cell protein/biologics production,farmland irrigation, anaerobic digestion, integrated ethanol-methane fermentation process and other technologies. This papersystematicallysummarized these technologies,elaborating theories. characteristic, advantages and disadvantages of these technologies in order to offer references for the further researches on the ethanol wastewater treatment.
