Problems solved by technology
[0002] At present, the aquaculture pollutants are mainly water-soaked manure and dry-cleaned manure. Among them, water-soaked manure is widely used because of its advantages of saving labor costs and convenient operation. All have been dissolved in water, resulting in poor fertilizer and low value
In addition, the traditional method of using compost to make organic fertilizer has problems such as biological water consumption and incomplete ripening.
What's more serious is that there are a large number of pathogens, antibiotics, insect eggs, grass seeds and other harmful substances in the feces. If they cannot be removed, they will cause secondary pollution to planting, especially vegetable planting, and even seriously affect human health and safety.

The invention provides a multistage curing evaporating preparation method of bio-organic fertilizer. The method includes following steps: primary curing: filling one of multiple storage tanks with a mixture through a distributor; delivering hot air generated through a biogas heating device to the storage tanks, and stirring for curing, wherein the number of curing days is equal to that of the storage tanks; secondary curing: putting the mixture after going through a secondary curing drum for curing for 1-2d; tertiary curing: conveying the mixture after going through secondary curing to a storing tank, and adding a functional strain according to material composition and carbon-nitrogen ratio for curing for 5-7d. Planting waste like straw and plant root and leaf is added into breeding dung to serve as a carbon source, pollutant wastewater in a biogas pool is added in the process of oxygen devourment curing, and heat provided by biogas effectively accelerates the curing process; the strain is added in multiple stages, so that effective amount of fermentation and functional bacteria is ensured.
Description
technical field [0001] The invention relates to the technical field of production and preparation of organic fertilizers, in particular to a method for preparing bio-organic fertilizers by multi-stage aging and evaporation. Background technique [0002] At present, the aquaculture pollutants are mainly water-soaked manure and dry-cleaned manure. Among them, water-soaked manure is widely used because of its advantages of saving labor costs and convenient operation. All have been dissolved in water, resulting in poor fertilizer and low value. In addition, the traditional method of using compost to make organic fertilizer has problems such as biological water consumption and incomplete ripening. What's more serious is that there are a large number of pathogens, antibiotics, insect eggs, grass seeds and other harmful substances in the feces. If they cannot be removed, they will cause secondary pollution to planting, especially vegetable planting, and even seriously affect human...
