Abstract

The invention discloses a biogas fermentation initiator and a preparation method thereof, and belongs to the technical field of biogas preparation through a biological fermentation method. The present problems of slow start, low gas yield efficiency, and no gas yield in the fermentation process are solved. The initiator is composed of the following raw materials: sludge in fishpond, wheat straw, animal manure, ammonium bicarbonate, and bacterium strains; wherein the bacterium strains are bacteroides succinoge-nes, butyrivibrio fibrisolvens, bacillus subtilis, saccharomycetes, methanosarcina, and methanosaeta. The biogas fermentation initiator is applied to biogas fermentation, can greatly shorten the start time (biogas can be produced after one day), and is capable of increasing the biogas yield and biogas generation speed.

Description

technical field [0001] The invention belongs to the technical field of preparing biogas by a biological fermentation method, and in particular relates to a biogas fermentation initiator and a preparation method thereof. Background technique [0002] As a big energy consumer in China, the development and utilization of new energy is of great significance to the sustainable development of the national economy. With the rapid development of rural social economy, rural energy consumption is also increasing; biogas is a clean, efficient and high-quality energy. The main component is CH 4 , the use of biogas can not only solve the problem of farmers' living energy, relieve energy tension, but also use waste to reduce environmental pollution. [0003] In this context, biogas resources, as a new energy source with great application prospects, its development and utilization is an effective measure to solve the problem of rural energy supply under the energy shortage situation, and ...
