0引言农村沼气建设是保护生态环境,改善农村卫生条件,促进农业和农村经济可持续发展的重要措施。随着农村沼气建设的不断发展,只有采取有效的科学管理措施,才能保证沼气池产气好、产气旺。根据多年实践经验,现将农村沼气池的主要技术管理措施概况为“一提高,两安全,三结合,四勤,五适宜”。1一提高提高沼气池内发酵温度。温度是沼气发酵的重要外因条件,温度适宜则细菌繁殖旺盛,活力增强,厌氧分解和生成甲烷的速度就快,产气就多,实践中在冬季提高沼气池内发酵温度常采用以下方法:
0 Introduction The construction of rural biogas is an important measure to protect the ecological environment, improve rural sanitary conditions and promote the sustainable development of agriculture and rural economy. With the continuous development of biogas construction in rural areas, only through effective scientific management measures can gas generation in biogas digesters be good and produce strong gas. Based on many years of practical experience, the main technical management measures of rural digesters are now “one to improve, two safety, three combined, four ground, five suitable ”. 1 to improve the digester fermentation temperature. Biogas fermentation temperature is an important external conditions, the temperature is suitable for the proliferation of bacteria, enhanced vitality, anaerobic decomposition and the rate of methane generation is fast, more gas production, practice in practice in the digester fermentation temperature in the following methods are often used:
