加强沼气池的科学管理,特别是越冬管理,是提高沼气产量的重要措施。几年来,各地沼气越冬管理试验证明,只要沼气池修建得法,又管理得好,沼气越冬问题是完全可以解决的。据介绍,天津市郊区静海县双塘公社八里庄大队,加强了沼气池的越冬管理,每天至少可供点燃两小时。黑龙江省桦南县攻克了一系列技术难关,在零下30℃情况下,做到沼气池正常产气,一年四季都能用沼气点灯做饭。我国南北方社员户用沼气池越冬管理的主要措施如下: 保证甲烷细菌有充分的营养物质在严寒来临之前要换一次料,除掉旧料,加足新料,为甲烷细菌在 Strengthening the scientific management of digesters, especially overwintering management, is an important measure to increase biogas production. Over the past few years, over-winter biogas management test proved that as long as biogas well constructed and well managed, biogas overwintering problem can be completely solved. It is reported that Balizhuang Brigade, Shuangtang Commune, Jinghai County, suburb of Tianjin, stepped up the winter management of biogas digesters and lit at least two hours a day. Huanan County, Heilongjiang Province to overcome a series of technical difficulties, at minus 30 ℃, the normal gas production digesters, biogas lighting can be used throughout the year to cook. China’s north and south members of the biogas digesters for household management over the winter main measures are as follows: to ensure that methane bacteria have adequate nutrients in the cold before the advent of a new material, remove the old material, add new material for the methane bacteria in
