摘要
为了研究哈尔滨地区地表层温度对地埋式沼气工程的影响,对哈尔滨地区地表层地面至地面-3m内的温度变化规律进行了一年多的跟踪测试。结果表明,哈尔滨地区地埋式沼气池由环境提供的温度距离厌氧发酵所需要的温度都有较大的差距。因此对沼气池的加热保温以及精确的温度控制是非常必要的。
In order to investigate the effects of earth surface temperature on the buried biogas project in Harbin, the paper tested the temperature changes from earth surface to -3 m-depth for more than one year. Earth surface temperature tests showed that there was large gap between environment temperatures and the needed temperature of buried anaerobic digestion in Harbin. So it is necessary to provide heat insulation and precise temperature control for biogas generating pit.
