Embodiment 1

[0049] A kind of production technology of the liquid micro-peptide fertilizer produced by compound enzymolysis of urban fresh garbage, comprising the steps:

[0050] (1) Raw material collection: collect 500kg of raw materials from fish slaughtering leftovers and some dead fish in the vegetable market;

[0051] (2) pretreatment: the raw material that step 1 is collected adds 200kg water and grinds the meat with a meat grinder and is broken into 40 order minced meat;

[0052] (3) Cooking and hydrolysis: add 350kg of water to the slurry treated in step 2, stir evenly, use tripotassium phosphate to adjust the pH value of the slurry to 8.5, keep stirring and gradually heat up to 89°C, and hydrolyze at a constant temperature for 1.5h , until the fluidity of the feed liquid is improved, and there is basically no graininess;

[0053] (4) Composite enzymatic hydrolysis: add 500kg of water together with the hydrolyzed feed liquid in step 3 and solid slag, adjust the temperature of the ...

Embodiment 2

[0058] A kind of production technology of the liquid micro-peptide fertilizer produced by compound enzymolysis of urban fresh garbage, comprising the steps:

[0059] (1) Raw material collection: collect a total of 500kg of raw materials from vegetable markets and supermarkets, slaughtered fish intestines and some dead fish;

[0060] (2) pretreatment: the raw material that step 1 is collected adds 150kg water and is crushed into 40 order minced meat with a meat grinder;

[0061] (3) Cooking and hydrolysis: add 600kg of water to the processed slurry in step 2, stir evenly, use tripotassium phosphate to adjust the pH value of the slurry to 9.5, continue stirring and gradually heat up to 90°C, and hydrolyze at a constant temperature for 2 hours;

[0062] (4) Composite enzymatic hydrolysis: add 500kg of water together with the solid slag hydrolyzed in step 3, adjust the temperature of the feed liquid to 55°C, stir evenly, and use liquid sodium hydroxide (the mass fraction of the co...

Embodiment 3

[0067] A kind of production technology of the liquid micro-peptide fertilizer produced by compound enzymolysis of urban fresh garbage, comprising the steps:

[0068] (1) Raw material collection: collect 300kg raw materials of chicken intestines and other poultry offal wastes slaughtered in the market;

[0069] (2) Pretreatment: add 150kg water to the collected raw material and crush it into 40 mesh pieces with a meat grinder;

[0070] (3) Cooking and hydrolysis: add 400kg of water to the processed slurry in step 2, stir evenly, use tripotassium phosphate to adjust the pH value of the slurry to 9.0, continue stirring and gradually heat up to 95°C, and hydrolyze at a constant temperature for 2 hours;

[0071](4) Composite enzymatic hydrolysis: add 310kg of water together with the solid slag hydrolyzed in step 3, adjust the temperature of the feed liquid to 57°C, stir evenly, and use liquid sodium hydroxide (the mass fraction of the concentration is 5%) Regulate pH value to 9.0;...

Abstract

The invention discloses a liquid micro-peptide fertilizer produced by compound enzymolysis of municipal fresh waste, a production process and the application of the liquid micro-peptide fertilizer. The production process comprises the following steps: (1) collecting raw materials; (2) pretreatment; (3) cooking and hydrolyzing; (4) compound enzymolysis; (5) filtering impurities; (6) adjusting; (7)filling and storing. On the basis of garbage treatment, molecular biology, enzyme engineering and plant nutriology technologies are utilized, a technical scheme of compound enzymolysis of multiple biological enzymes is adopted, and the protein peptide is extracted from the fresh garbage and applied to the field of agricultural planting. On one hand, the problem of urban fresh garbage treatment issolved, wastewater and waste residues are basically not generated in the treatment process, and environmental protection and high efficiency are achieved; on the other hand, a nutrient resource cyclicutilization mode is adopted, and a new thought and a solution are provided for agricultural organic planting.

Description

technical field [0001] The invention belongs to the technical field of preparation of liquid micro-peptide fertilizer, and in particular relates to a liquid micro-peptide fertilizer produced by compound enzymatic hydrolysis of municipal fresh garbage, a production process and its application. Background technique [0002] Urban fresh waste disposal is a difficult problem in major cities. Every day, a large amount of fresh waste will be generated from vegetable markets, supermarkets, Sanniao slaughtering markets, aquatic products markets, pig, cattle, sheep slaughtering plants and other places in cities. These include the leftovers of slaughtered fish, chickens, ducks, geese, pigs, cattle, and sheep, such as fish gills, fish intestines, fish heads and bones, fish skin and scales, chicken intestines, dead fish and shrimps that are not fresh, and expired meat products, expired or slightly spoiled frozen meat products, confiscated zombie meat, etc. This kind of garbage can usua...
