餐厨垃圾两相厌氧发酵技术研究和应用进展

近年来,我国餐厨垃圾产生量逐年增加其无害化、減量化和资源化处理越来越受到人们的重视。两相厌氧发酵因其将水解酸化阶段和产甲烷阶段分离克服了单相厌氧发酵易酸化、运行不稳定等问题,正逐渐成为餐厨垃圾资源化处理的重要选择。综述了餐厨垃圾两相厌氧发酵工艺的控制參数、发酵原料和反应器等方面的最新研究和应用进展,总结了该工艺在研究和应用中存在的一些问题展望了两相厌氧发酵用于餐厨垃圾处理的发展前景。

Research Progress of Two-phase Anaerobic Fermentation Technology and Application of Kitchen Waste

With the increasing production of kitchen waste in our country, its harmlessness, decrement and resource treatment gets more and more attention. In two-phase anaerobic fermentation technology,hydrolysis acidification phase and methanogenic phase were relatively independent, which can avoid acidification and instable operation for the single-phase anaerobic fermentation. In order to provide reference for the harmlessness, decrement and resource treatment of kitchen waste in our country,this paper analysed the two-phase anaerobic digestion process, and mainly discussed the research progress of control parameters, fermentation materials, reactor of two-phase anaerobic digestion for kitchen waste. At last, the further research in the future were prospected.
