specific Embodiment approach 1

[0011] Specific embodiment one: In this embodiment, the biogas preparation method using edible fungus chaff as a raw material is carried out according to the following steps: 1. Pretreatment of edible fungus chaff: first remove the sundries in the fungus chaff, pulverize it, and then dry it in the air. Then add the composite microbial bacterial agent according to 10%~20% of the quality of the dried bacterium chaff to obtain the mixture, then adjust the water content of the mixture to 50%~60%, seal it, and carry out anaerobic fermentation for 2~3 days; 2. Mix the bacterium chaff after step one treatment with cow dung, then join in the fermenter, adjust the content of solid matter in the fermenter to 20% (weight), control the biogas fermentation temperature to be 30~40 ℃, the packing tank of the fermenter The capacity is controlled at 70% to 80%, and after 25 to 45 days, a batch of biogas fermentation is completed; in step 1, each milliliter of compound microbial agent contains 2...

specific Embodiment approach 2

[0015] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the compound microbial bacterial agent is added according to 12% to 18% of the weight of the dried fungus chaff. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0016] Embodiment 3: The difference between this embodiment and Embodiment 1 is that in step 1, compound microbial bacterial agent is added according to 15% of the weight of the dried fungus chaff. Others are the same as in the first embodiment.

Abstract

The invention discloses a biogas preparation method using edible fungus chaff as a raw material, and relates to a biogas preparation method. The invention aims to solve the problems of waste of resources and environmental pollution caused by discarding or burning the chaff after the production of edible fungi. Method: first remove the sundries in the chaff, crush it and dry it, then add the compound microbial agent, seal it, and ferment it anaerobically; mix the treated chaff with cow dung, then add it to the fermentation tank, and adjust the fermentation tank The content of solids, the temperature of the biogas fermentation, and the capacity of the fermentation tank are controlled. After 25 to 45 days, a batch of biogas fermentation is completed. The invention uses the waste fungus chaff after the production of edible fungi as the fermentation raw material, solves the problem of environmental pollution caused by the discarded fungus chaff, turns waste into wealth, and does not cause secondary pollution to the environment. Applied in the field of biogas fermentation.

Description

technical field [0001] The invention relates to a biogas preparation method. Background technique [0002] With the vigorous development of industrialization and factoryization of edible fungi, there are more and more wastes after the production of edible fungi, and the treatment has become a prominent problem. Mushroom chaff is often discarded or burned anywhere, which not only causes serious pollution to the surrounding environment, but also causes a great waste of resources and affects the reproduction of edible fungi. Mushroom chaff is the residue of edible fungi degrading plant-derived crude fiber cultivation materials, and contains various nutrients such as unused fiber, bacterial protein, secondary metabolites, and trace elements. Therefore how to make full use of the fungus chaff to turn waste into wealth has become an urgent problem to be solved. Contents of the invention [0003] The present invention aims to solve the problem of resource waste and environmenta...
