How did the winter biogas digesters pass through the spring?

After the festival, the temperature gradually warmed. Farmers were using a winter biogas digester, and it appeared that the quality of spring gas was not as good as one day a day. The flame went from red to red and began to dance a few days later. Only produce odor, no fire. "I have used it well in winter. Why can't spring be used?"

The main reason is that the farmers did not pay attention to the concentration of excrement when adding manure to the biogas digesters. Before the winter season, the temperature of the biogas digesters decreased. The farmers used less water in the circle, which did not increase the concentration of fermentation raw materials in the biogas digesters, thus ensuring the biogas digesters winter. The use of gas. After spring, there was no increase in the amount of water used in the rising temperature circle, which led to the “spring disease” after the biogas tank entered March.

Treatment method: After the Spring Festival, the amount of water should be increased, and raw materials should be added in the concentration of raw materials in summer to gradually replace the high concentration of fermentation raw materials in winter. This is the fundamental method for biogas digesters not to be a spring disease.

For biogas tanks that have acquired “spring disease,” lighter people (when the flames start dancing from red to red) are added with lime water, which reduces the concentration of fermentation raw materials and can be used after a few days. The heavy (adding lime) was added to reduce the concentration of the fermentation raw material, and then the good biogas slurry was added again. For the decommissioning of a biogas digester for more than one month, the old fluid must be halved and re-injected into the fermentation raw material and biogas slurry at a concentration of 6%.
