我国城市生活垃圾分类与有机垃圾处理方法探究

摘要

Municipal solid waste classified collection and processing is the main way to deal with garbage in developed countries, while our country is still lack of technical and experience in this respect. By describing the current situation of municipal solid waste as well as national regulations and policies, this paper analyzes the reason of urban living garbage classified collection and disposal policy can not be implemented. Living garbage classified collection and processing is an inevitable trend. After separate collection, the existing waste disposal methods can not meet the needs of waste treatment. Aiming at the problem of slow reaction rate of compost anaerobic treatment, a suggestion of anaerobic digestion of organic garbage and excess activated sludge is proposed.%城市生活垃圾分类收集与处理是目前发达国家处理生活垃圾的主要方式。在这方面，我国的技术经验还相对缺乏。通过阐述当前我国城市生活垃圾现状以及国家法规政策，从多方面分析了我国城市生活垃圾分类收集与处理政策不能落实的原因。认为，生活垃圾分类收集与处理是必然趋势，分类收集后，现有的垃圾处理模式已无法满足需要，垃圾的处理方式也需要进一步改进。最后针对堆肥厌氧处理有机生活垃圾反应速率慢的问题，提出了有机生活垃圾与剩余污泥结合厌氧消化的改进方法。
