Description
Technical field
The present invention relates to technical field of biological organic fertilizer, and in particular to a kind of cow dung resourceization is utilized and produces biological organic fertilizer
Production technology.
Background technology
With flourishing for beef farming, into a great problem, the COD contents of fowl and animal excrement are much for cow dung pollution
More than industrial wastewater and the COD discharge capacity sums of sanitary sewage.Cow dung can be used as fertilizer, feed and fuel, but by cow dung resource
Change extremely low using the utilization rate for producing organic fertilizer, a great deal of be directly discharged to around animal farm, the foul smell for distributing and growth
Mosquito had a strong impact on surrounding enviroment and jeopardized human health.Biological organic fertilizer is organic solid waste through bio-fertilizer strain
Fermentation, deodorant and post-processing of becoming thoroughly decomposed completely organic fertilizer, can nurse one's health soil, activation Soil Microorganism enliven rate,
Overcome soil hardening, increase soil air permeability.Used as a large agricultural country, fertilizer demand amount is huge, with China for China
The development of Green Food Industry, the demand of organic fertilizer is continuously increased, and domestic market biological organic fertilizer occupation rate and flourishing state
Family differs greatly.Existing biological organic fertilizer has production fermenting speed causes cost to raise slowly, does not become thoroughly decomposed fully and causes burn seedlings,
Product viable count problem not high, and product processes selection be influence biological organic fertilizer cost and quality it is important because
Element, needs further perfect.
The content of the invention
It is an object of the invention to provide a kind of cow dung resourceization using the production technology for producing biological organic fertilizer, life is solved
