Embodiment 1

[0026] Wheat straw is crushed to less than 15mm, sprayed into yeast fermentation wastewater to a moisture content of 60%, and mixed with a compound microbial agent with a raw material amount of 1wt%, using conventional fermentation bin composting, strip composting or static composting methods Fermentation is carried out, when the temperature of the material rises to 50°C, the composting starts, and the fermentation temperature is controlled at 50-70°C, and the temperature of the material begins to drop after 5-15 days. Soft and elastic to hold, easily broken after drying, slightly fragrant or fermented.

[0027] The above-mentioned composite microbial bacterial agent includes the ratio of the number of microorganisms in the following microbial raw materials: Trichoderma pseudoconii: Bacillus subtilis: Bacillus megaterium: Micromonas: Streptomyces: Candida tropicalis 1: Nocardia: albino Sapros: Vibrio vulgaris: Klebsiella: Chaetomium thermophila: Agrobacterium: Rhizopus: Lactic...

Embodiment 2

[0031] Corn stalks are crushed to less than 20mm, sprayed into glutamic acid fermentation waste water to a moisture content of 70%, mixed with a compound microbial agent with a raw material amount of 5wt%, using conventional fermentation bin composting, stack composting or static composting The method is to carry out fermentation. When the temperature of the material reaches 50°C, it starts to turn over. The fermentation temperature is controlled at 50-70°C. After 15 days, the temperature of the material begins to drop. It is soft and elastic, easy to break after drying, slightly fragrant or fermented.

[0032] The ratio of the number of microorganisms in the composite microbial agent is: Trichoderma pseudoconii: Bacillus subtilis: Bacillus megaterium: Micromonas: Streptomyces: Candida tropicalis: Nocardia: White rot fungus: common Vibrio cellulosus: Klebsiella: Chaetomium thermophila: Agrobacterium: Rhizopus: Lactic acid bacteria: Micromonas: Pseudomonas fluorescens: Rhizobiu...

Embodiment 3

[0036] Wheat straw powder and apple leaves crushed to less than 15mm are sprayed into yeast fermentation wastewater to a moisture content of 60%, and a compound microbial agent with a raw material amount of 2.5wt% is added to mix evenly. Ferment by composting or static composting, turn the compost when the fermentation temperature reaches 50°C, control the fermentation temperature at 50-70°C, and the temperature of the material begins to drop after 5-15 days. Dark brown, soft and elastic to hold, easily broken after drying, slightly fragrant or fermented.

Abstract

The invention relates to a method for producing a bio-organic fertilizer through fermentation wastewater and agricultural waste. The method comprises the following steps: crushing the agricultural waste so as to enable the agricultural waste to be smaller than 20 mm; spraying the fermentation wastewater on the crushed agricultural waste and uniformly mixing, and controlling the water content to be 55-70 percent and pH to be 6-9; adding a compound microbial agent in the mixed material for fermenting, wherein the adding amount of the compound microbial agent is 0.05-5 weight percent of that of the raw material; when the temperature of the materials rises to 50 DEG C, starting to turn and compost, and controlling the fermentation temperature to be 50-70 DEG C and the fermentation time to last for 5-15 days; at the end of fermentation, enabling 1 / 3-1 / 2 of compost to collapse; airing to obtain the bio-organic fertilizer. As the fermentation wastewater is not processed and is directly used for fermentation production of the organic fertilizer, the composting time can be shortened, the production water consumption is reduced, and the no poison, harmlessness, no smell and no environment pollution are achieved. Meanwhile, nutrients can be preserved, the content of organic matters in the fertilizer is increased, and therefore the quality of the fertilizer is improved.

Description

technical field [0001] The invention relates to a method for producing bio-organic fertilizer, in particular to a method for producing bio-organic fertilizer from fermented wastewater and agricultural waste, and belongs to the field of bio-fertilizers. Background technique [0002] Fermentation wastewater contains a large amount of nutrients. If it is discharged directly, it will bring huge pollution to the environment and cause eutrophication of the water body. Now the fermentation factory discharges the fermentation wastewater after aerobic and anaerobic treatment, although the harm to the environment is reduced, but the production cost is increased. [0003] Fermentation wastewater has high nutrient content, and many components can be directly utilized by microorganisms. In the process of fermenting agricultural waste to produce organic fertilizer, a large amount of water needs to be added. Contents of the invention [0004] The technical problem to be solved by the p...
