摘　　要：为了将农村有机生活垃圾作为厌氧发酵原料提供理论依据,以江苏省徐州市沛县大屯街道王庄村生活垃圾分类处置中心的有机生活垃圾为研究对象,连续12月次对有机生活垃圾堆垛进行多点采样,分析沛县大屯街道有机生活垃圾的理化特征。结果表明,分类后沛县大屯街道有机生活垃圾含水率为75%~80%;有机碳含量约为40%;全氮含量较高,为12~26 g/kg;碳氮比(C/N)主要为17~23;木质素含量为3%~13%。可以看出,沛县大屯街道有机生活垃圾适合作为厌氧发酵物料。To provide theoretical basis for using organic domestic waste as fermentation material in rural areas,the organic domestic waste from domestic waste classification and disposal center in Wangzhuang Village,Datun Street,Pei County,Xuzhou City,Jiangsu province was selected as the research object.The physical and chemical characteristics of organic domestic waste in Datun Street,Pei County were analyzed by multi-point sampling for 12 months consecutively.The results showed that the moisture content of organic domestic waste in Datun Street of Pei County ranged from 75%to 80%after classification,the organic carbon content was about 40%,the total nitrogen content was 12-26 g/kg,the carbon-nitrogen ratio(C/N)was 17-23,the content of lignin was 3%-13%.It can be seen that organic domestic waste in Datun Street of Pei County is suitable for anaerobic fermentation material.
