Description
Technical field
The present invention relates to a kind of method that straw prepares biogas and compoiste fertilizer, belong to solid recycling skill
Art field.
Background technology
In the last few years, severe contamination air after straw burns, if recycling, not only solves air pollution and asks
Topic, and energy shortage problem can be alleviated as resource.The purposes of current straw mainly has three aspects, and one is to make
For biomass power generation, two is as fuel utilization heat energy, and three is to prepare biogas and fertilizer as fermentation raw material.Compare it
Under, preparing biogas and fertilizer as fermentation raw material is that the horizontal highest of current recycling is a kind of, not only realizes waste
Complete resource, and do not produce secondary pollution, economic benefit and obvious environment benefit.
It is to first pass through the mud one time fermentation preparation after adding domestication that straw prepares biogas and the principle of fertilizer
Biogas, the biogas residue after preparation adds straw, plant ash and bone meal to carry out secondary compost fermentation and prepare fertilizer, secondary compost
The straw that fermentation adds does not need to pulverize, and the completely straw that do not ferment on a small quantity returns the fertile fermentation of system by screening
Pond.The method low cost, biogas output is big, and the fertilizer fertilizer efficiency of preparation is high.
