加强农村户用沼气池的日常管理对最大限度发挥沼气池带来的综合效益至关重要。入秋以来,气温逐渐降低,甲烷菌的繁殖速度就会相应下降,影响沼气池的产气。尤其到了冬季,池温更低,产气率进一步降低,如果日常管理维护不到位就会停止产气。为提高农户沼气池管理的能力,建议如下。1在入冬前沼气池要彻底换料一次加足新料以保证冬季发酵需要的养料,促进甲烷菌的活动。发酵浓度可控制在8%左右,要加太阳晒过的温水以
Strengthening the day-to-day management of household digesters in rural areas is crucial to maximize the combined benefits of digesters. Since autumn, the temperature gradually decreased, the rate of propagation of methane bacteria will be reduced accordingly, affecting gas production digesters. Especially in winter, the pool temperature is lower, the gas production rate is further reduced, and gas production will be stopped if the daily management and maintenance are not in place. To improve the capacity of farmers digesters management, the following recommendations. 1 Before the end of winter biogas digesters should be thoroughly refilled at one time to add enough new materials to ensure the nutrients needed for winter fermentation to promote the activity of methanogens. Fermentation concentration can be controlled at about 8%, plus the sun to the warm water
