摘　　要：有机固废的高效转化和循环利用对解决全球环境污染、能源短缺和资源缺乏等共性问题具有积极作用。采用厌氧发酵技术高效处理有机固废,可合成制备出不同酸化产物,并促进酸化产品的加工应用。在文献及工程调研的基础上,梳理了有机固废厌氧酸化发酵的不同代谢途径,分析了不同酸化产物的经济性及工程化应用现状。以发酵产物乙醇、乳酸、丙酸和丁酸等为代表,分析了酸化产品的制备及应用状况。采用系列宏观与微观的调控手段,可促进酸化发酵目标产物的代谢转化,并实现有机固废酸化发酵脂肪酸类产物的高效合成,从而为发酵脂肪酸类产品的制备生产和加工应用提供参考。The conversion and recycling of organic waste play a positive role in addressing environment pollution,global energy and resource shortage.Using anaerobic fermentation technology to treat organic solid waste efficiently can promote the synthesis and preparation of different acidification products and the processing and application of typical products.Based on literature review and site survey,different metabolic pathways of anaerobic acidification fermentation were reviewed,and the economic efficiency and engineering application status of different acidification products were evaluated.The preparation and application condition of products of different fermentation types,e.g.ethanol,lactic acid,propionic acid and butyric acid,were introduced.The adoption of oriented micro and macro strategies can promote the metabolic synthesis of target fermentation products and efficient transformation of fatty acid products in acidification fermentation of organic solid waste,which can lay a theoretical foundation and provide engineering guidance for the preparation,production and processing application of fermented fatty acid products.
