沼气池的越冬管理,除池内增温、池外保温外,还须加入添加剂,促进发酵细菌的生长繁殖,以加速沼料分解,提高产气量。现将常用的添加剂介绍如下: 1.热性发酵原料 如豆腐坊、酒坊、粉坊、屠宰场的下脚热水等。这些热性废弃物直接入池或经沉淀入池,可提高池温,增加产气量。 2.碳酸氢铵 用量为原料体积的0.1％～0.3％,掉在原料中投入池内发酵,可提高产气量30％左右。 Biogas overwintering management, in addition to the pool warming, pool insulation, but also have to add additives to promote the growth and reproduction of fermentative bacteria to accelerate the decomposition of biogas to improve gas production. The commonly used additives are introduced as follows: 1. Thermal fermentation of raw materials such as bean curd Square, wine Square, Fenfang, slaughterhouse foot hot water. These thermal waste into the pool or directly into the pool, can increase the pool temperature, increase gas production. 2. Ammonium bicarbonate dosage of 0.1% to 0.3% of the volume of raw materials, out of raw materials into the pool fermentation, can increase gas production by about 30%.
