沼气池的越冬管理,用通常话说就是“吃饱肚子,盖暖被子,池内要增温,池外要保温,”为了使沼气发酵原料不受冬春季节气温影响,除加强沼气池保温管理外,还要对生产沼气的物质基础采用适应的技术措施。利用热性发酵原料作为添加剂,为发酵细菌提供生长繁殖所需的微量元素,可加速有机物的分解,提高产气量。现就有关添加剂及应用技术介绍如下。 1.热性发酵原料如豆腐坊、酒坊、粉坊、屠宰场下脚热水等,这些热性废弃物直接投入池内或经沉淀入池,可提高池温。增加产气量。 2.碳酸氢铵添加剂用量为原料容积的0.1—0.3,伴在原料中投入池内发酵,可
Biogas overwintering management, in general, is “full stomach, covered quilts, the pool to be warming, outside the pool to be insulated,” in order to make the biogas fermentation of raw materials from winter and spring temperatures, in addition to strengthening the digester insulation management , But also to adapt to the material basis for the production of biogas technology measures. The use of raw materials as a thermal fermentation additives, fermentation bacteria to provide the necessary growth and reproduction of trace elements, can accelerate the decomposition of organic matter, increase gas production. Now on the additives and application of technology are as follows. 1. Thermal fermentation of raw materials such as bean curd Square, wine Square, Fenfang, slaughterhouse under the foot of hot water, these thermal waste directly into the pool or sedimentation into the pool, can increase the pool temperature. Increase gas production. 2. Ammonium bicarbonate additive dosage of 0.1-0.3 volume of raw materials, with the raw materials into the pond fermentation,
