摘要
中国农村沼气发酵温度适宜性区划对中国农村沼气合理布局具有重要的意义。以沼气发酵温度为研究对象,系统分析了温度与沼气发酵之间的关系及沼气池发酵液的温度与气温、地温之间的关系,以最低发酵温度(12℃)的发酵时间和发酵较快温度(20℃)的发酵时间作为中国农村沼气发酵温度的适宜性分区指标,对中国农村沼气发酵温度适宜性进行分区,划分为沼气发酵温度最适宜区、适宜区、次适宜区和非适宜区并进行分区描述。分区结果表明:发酵温度最适宜区包括福建、广东、广西、海南、云南5个省(区);发酵温度适宜区包括浙江、湖北、湖南、贵州、重庆、江苏、江西、四川、上海、河南、山东、安徽、天津、北京、河北15个省(市);发酵温度次适宜区包括山西、辽宁、吉林、甘肃、新疆、宁夏、陕西、内蒙古8个省(区);发酵温度非适宜区包括黑龙江、西藏、青海3个省(区)。在此基础上,形成了中国农村户用沼气发酵原料适宜性区划图。
It＇s significant to research household biogas fermentation temperature in rural China for rational distribution of biogas digester. The relationship among air temperature, ground temperature and digester temperature was analyzed. The index for China＇s rural household biogas fermentation temperature division was built. According to the temperature suitability, the development of household biogas can be divided into four different regions in rural China, optimum region including suitable region, sub-suitable region and unsuitable region. Results showed that Fujian, Guangdong, Guangxi, Hainan, Yunnan were in the optimum regions, Zhejiang, Hubei, Hunan, Guizhou, Chongqing, Jiangsu, Jiangxi, Sichuan, Shanghai, He＇nan, Shandong, Anhui, Tianjin, Beijing, and Hebei were in the suitable regions. Shanxi, Liaoning, Jilin, Gansu, Xinjiang, Ningxia, Shaanxi, Inner Mongolia are in the sub-suitable regions, and Heilongjiang, Tibet, Qinghai were in the unsuitable regions. According to these results, biogas fermentation temperature zoning map in rural China was made.
