沼气池内发酵液的温度对产生沼气有很大影响。据有关资料介绍:发酵液温度如降至8℃以下,沼气菌几乎停止活动,不再产气。因此,在北方地区,沼气池越冬必须采取适当的保温措施,才能保证正常产气。静海县东双塘公社八里庄大队科技队的沼气越冬措施简易,产气效果良好。他们吸取当地菜农建阳畦 Biogas fermentation broth temperature has a great impact on the production of biogas. According to the information on the introduction: fermentation broth temperature dropped below 8 ℃, biogas almost stopped activity, no longer gas. Therefore, in the northern region, biogas overwintering must take appropriate insulation measures in order to ensure normal gas production. Jinghai County Shuangshitang commune Balizhuang Brigade team biogas overwintering measures simple, gas production is good. They learn from local farmers to build Yang 畦
