农村生活垃圾厌氧发酵产沼气潜力研究

旨在对农村有机生活垃圾厌氧发酵产沼气的潜力进行研究。对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每月1次采集样品，并对一周年十二个月份的生活垃圾样品进行批式中温厌氧发酵产气潜力研究，考察农村生活垃圾作为发酵原料周年沼气产量和甲烷产量的变化，各月份试验组的累积沼气产气量范围为447～1 398 mL、累积甲烷产气量范围为215～865 mL。并用SPSS数据分析发现农村生活垃圾含水率、总磷TP、总钾TK、总氮TN、有机质、C/N、半纤维素、纤维素、木质素的含量均对产沼气潜力有影响，其中纤维素含量会对产沼气潜力有显著的正向影响关系，而TP会对产气潜力产生显著的负向影响关系，最后，该研究根据生活垃圾理化性质数据基础上建立了多元线性逐步回归最优方程，可根据农村有机生活垃圾的含水率、纤维素和木质素的含量预测其厌氧发酵产沼气潜力。

Potential of biogas produced from anaerobic fermentation of rural household wastes

In recent years, the improvement of the living standards of farmers has led to a sharp increase in the discharge of household waste in villages and towns. The focus on the work of ecological livability is the highlights of the treatment of household waste in villages and towns. Therefore, solving the problem of rural household waste has become the top priority of the rural revitalization strategy. The main components of rural organic household waste are leftover food and melon peel, which are rich in organic matter, high water content, and sufficient nutrients. Hence, rural organic household waste may be suitable for the raw material to use in anaerobic fermentation. The method of anaerobic fermentation can degrade organic household waste, produce biogas, and digested. The product of the fermentation can also be used as a slow-release fertilizer to improve the soil condition and fully realize the
