北京市夏村沼气集中供气工程案例分析

Case Study of Centralized Biogas Supply Project in Xia Village of Beijing

农村社会环境和经济条件的改善,以及城乡统筹和现代农业发展,为农村沼气建设的多元化发展提供了崭新的机遇和更广阔的空间,特别是沼气集中供气工程,符合农村发展的大趋势,更具有代表性和典型性。文章以北京市房山区夏村大中型沼气集中供气工程为例,根据沼气销售统计记录,分析了村民一年四季以及各个月份的用气规律,并通过深入农户调查统计,研究了村民的能源消费结构。研究发现,冬季相对于其他季节,户均月用气量显著增加,比夏季、秋季、春季分别高出10.3%,13.5%,18.2%;同时,在新农村建设中,炊事用能已经退居到微不足道的比例,取而代之的是生活其他方面用能的需要,为沼气等新能源的广泛开发提出了更高的要求。

New opportunity of developing centralized biogas supply project are provided by the improvement of rural social environment and economic conditions,as well as urban-rural integration and modern agricultural development,which is conforming to the trend of rural development. Taking the centralized biogas supply project in Xia village of Fangshan District of Beijing as an example,the biogas consumption regularity every month throughout the year were analyzed based on the sale recording of biogas. The energy consumption structure of villagers were also investigated. The results showed that the villager＇s biogas consumption in winter was significantly high,which was 10. 3%,13. 5%,18. 2% higher than that in summer,autumn and spring,respectively. The proportion of energy for cooking had become trivial in the new rural construction,replaced by the energy consuming of other aspects in daily life,which means higher requirements for biogas and other new energy development.
