中国餐厨垃圾资源化利用系统建设现状研究

中国餐厨垃圾具有高油、高盐、含水率高、高有机质的特点,具备废物和资源两重性,将其单独回收利用十分必要。在分析餐厨垃圾回收利用、政策法规体系建设以及资源化技术现状的基础上,指出了资源化处理能力存在较大的缺口、缺乏国家层面统一立法、监管主体混乱等问题。基于现有的厌氧制沼、好氧制肥、生物转化以及综合集成技术的特点分析,得出协同厌氧处置、生物转化蛋白饲料、构建多元化技术体系以及产业联动集中布局是餐厨垃圾资源化技术的发展趋势。

Current Situation of Food Waste Recycling in China

The food waste in China has the characteristics of high oil,high salinity, high moisture content and high organic particulate matter content. The food waste is both a waste and a resource,and it is of great necessity to collect and recycle food waste separately. Based on the current situation of food waste recycling, policy system and disposal technologies, problems are pointed out that the current disposal capacity is far from enough,the national legislation is deficient,and the responsibility for reg-ulators is ambiguous. The characteristics of anaerobic digestion,aerobic composting,biotransformation and multiple technologies are introduced. The conclusion is drawn that anaerobic co -digestion, biotransformation, multiple technologies and industrial linkage are the development tendency of food waste recycling in China.
