餐厨垃圾资源化利用及其过程污染控制研究进展

餐厨垃圾年产生量大、成分复杂，传统的焚烧、填埋处理方式易引发一系列环境问题，同时，餐厨垃圾又具有有机质含量高、营养元素丰富的特点，其资源化利用可实现价值再生，符合可持续发展的要求，因而成为国内外学者的研究热点。本文从产品利用方向的角度综述了几类餐厨垃圾资源化利用技术的研究进展，包括能源化利用方向的餐厨垃圾制生物柴油、甲烷、氢、燃料乙醇技术，农业化利用方向的餐厨垃圾制动物饲料、有机肥料技术，工业化利用方向的餐厨垃圾制还原糖、炭材料、乳酸技术；介绍了餐厨垃圾资源化过程中产生的恶臭气体、废水污染问题以及污染控制相关研究进展。最后指出，对微生物厌氧反应机制的深入研究有利于实现相关技术在工业生产规模的优化，厨垃圾资源化工艺过程的污染控制需要进一步得到关注。

Research progress in resource utilization of kitchen waste and its process pollution control

A large quantity of kitchen wastes were produced every year in China with complicated composition,which led to a series of environmental problems when disposed with traditional treatments like incineration or landfill. Besides,kitchen wastes were abundant of organic matters and nutrients,the recycling value of which made it a research hotspot in the world. In this article,three kinds of recycling technologies were reviewed from the perspective of utilization direction,including biodiesel,methane, hydrogen,ethanol production in energy production direction,animal feed,organic fertilizer production in agricultural direction,and reducing sugar,carbon material,lactic acid production in industrial utilization. Research progress of pollution control in utilization process was reviewed. According to the analysis of those technologies,further research on mechanism of bio-anaerobic process is the future research emphasis,for the sake of full scale optimization. Process pollution control of kitchen waste utilization needs further attention.
