Problems solved by technology

[0003] However, there are some problems in the existing organic fertilizer production process: during the fermentation process, the materials cannot be fully converted into substances that can better promote the growth of crops, and the fermentation process is a semi-open or fully open environment, and the ammonia and carbon dioxide produced during the fermentation process , hydrogen sulfide or sulfur dioxide and other gases seriously pollute the environment, and the water removal process in the later stage of fermentation materials consumes a lot of energy.
[0004] Patents CN101602623, CN1548405, CN1397525 etc. have reported the method of using functional bacteria including photosynthetic bacteria, lactic acid bacteria, saccharomyces, Gram-positive actinomycetes, etc. Synergistic fermentation of multiple bacteria composed of lignin-decomposing bacteria, proteolytic bacteria and other beneficial bacteria has not been reported

Embodiment 1

[0021] Example 1 Preparation of modified activated carbon (Refer to the method reported by Fu Chengcheng et al., Research on the adsorption performance of modified activated carbon to ammonia. Journal of Basic Science of Textile Universities, Vol. 22, No. 3, 386-389)

[0022] Weigh 50g of activated carbon, add 75mL of 45% sodium hydroxide solution, shake at room temperature for 12 hours, then let it stand for 12 hours, filter out the impregnating solution, wash with deionized water until neutral, dry at 105°C before use.

Embodiment 2

[0023] Example 2 Preparation of modified activated carbon (Refer to the method reported by Fu Chengcheng et al., Research on the adsorption performance of modified activated carbon to ammonia. Journal of Basic Science of Textile Universities, Vol. 22, No. 3, 386-389)

[0024] Weigh 50g of activated carbon, add 75mL of 40% citric acid solution, shake at room temperature for 12 hours, then let it stand for 12 hours, filter off the impregnating solution, wash with deionized water until neutral, dry at 105°C for later use.

Embodiment 3

[0025] The production method of embodiment 3 organic fertilizers, prepare product according to the following steps:

[0026] (1) Mix 340 kg of pig manure, 80 kg of crushed straw, 25 kg of fly ash, 30 kg of phosphate rock powder, supplemented by 25 kg of humic acid, and mix well to adjust the humidity and pH value

[0027] (2) Mix 21 grams of cellulolytic bacteria and hemicellulolytic bacteria, 25 grams of lignin-decomposing bacteria and protein-decomposing bacteria, 24 grams of EM bacteria and 4.5 kg of fermented soybean meal in proportion, then inoculate into organic materials and mix uniform.

[0028] (3) Closed fermentation, follow-up and control in the middle process; open the blast system to ensure that the fermentation environment is in a suitable state; open the waste gas absorption system after a certain period of time, so that the waste gas enters the adsorption tank; finally open the discharge valve (connected to the filter with modified activated carbon) ). Repeat...

Abstract

The invention discloses a novel process for producing an organic fertilizer, which comprises the steps of: proportioning raw materials scientifically, wherein the main raw materials comprise crop straws, livestock and poultry excrements and the like; adding a defined amount of powdered coal and inorganic mineral powder and the like, wherein a small quantity of humic acid is prepared in the raw materials; and then, aerobically fermenting multi-microorganism, wherein the fermentation is more thorough and the nutrient balance is better. A solar fermenting tower is adopted in the invention, and adouble waste gas absorbing system is matched with the solar fermenting tower, therefore, the invention avoids environment pollution. The quality of agricultural products is improved by applying the fertilizer of the invention, and the crop yield is enhanced.

Description

technical field [0001] The invention relates to a new production process of organic fertilizer, which utilizes multi-bacteria synergistic fermentation and uses a solar fermentation tower for closed fermentation. In particular, the process of the invention is green and environmentally friendly, and adopts a double exhaust gas absorption system, which can basically achieve zero emission. Background technique [0002] Agricultural production, agricultural product processing, livestock and poultry breeding, and residents’ daily life will generate a large amount of waste, which not only occupies a large amount of land, but also causes direct, compound, and cyclic “water, Land and air" three-dimensional pollution, seriously damaging the ecological environment. The use of agricultural organic waste to produce organic fertilizer is of great significance for reducing environmental pollution and improving the comprehensive benefits of agriculture. Closely related. [0003] However, ...
