【摘要】 目前餐厨垃圾处理方式有粉碎直排、填埋处理、焚烧、堆肥处理、饲料化处理、生物发酵制氢、厌氧消化产甲烷、发酵产酒精等。分析其不足之处并突出能源化处理对环境影响小,应用前景广阔。此外,利用厨余垃圾制取乳酸,进而合成生物降解性塑料(聚乳酸)的技术,可为治理困扰人类的"白色污染"做出贡献。更多还原

【Abstract】 At present,the treatment methods of kitchen wastes include crushing and discharging directly,landfill disposal,incineration,composting disposal,producing hydrogen through bio-ferment,producing methane by anaerobic digestion,producing ethanol by fermentation and so on.Analyzing the disadvantages of some treatment methods,it has less influence on environment during converting wastes to energy,which has broad application prospect.Furthermore,the technology of using biodegradable plastics(poly-lactic acid) synthesized by lactic acid produced from food wastes can help to eliminate the problem of the" white pollution".更多还原
