Embodiment 1

[0037] The invention provides a method for preparing organic fertilizer from kitchen waste and animal and plant waste, comprising the following steps:

[0038] Step 1. Select the meat waste and bones in the kitchen waste, break or chop other waste in the kitchen waste, and set aside;

[0039] Step 2, smashing or chopping the plant-type waste, and set aside;

[0040]Step 3. After separating the meat, bones, blood and hair of the animal waste, cook the meat separated from the animal waste, take it out, drain it, and mix it with the meat waste in the kitchen waste Chopped into meat strips with a length of 1cm; the bones separated from animal waste and the bones in kitchen waste are mixed and ground into bone meal; the hair is soaked in an aqueous solution containing keratinase at a temperature of 40°C After 2 hours of enzymatic hydrolysis, the enzymatic hydrolyzate is obtained, which is used for later use; the main component of feathers is keratin, and keratinase is a kind of pr...

Embodiment 2

[0064] The invention provides a method for preparing organic fertilizer from kitchen waste and animal and plant waste, comprising the following steps:

[0065] Step 1. Select the meat waste and bones in the kitchen waste, break or chop other waste in the kitchen waste, and set aside;

[0066] Step 2, smashing or chopping the plant-type waste, and set aside;

[0067] Step 3. After separating the meat, bones, blood and hair of the animal waste, cook the meat separated from the animal waste, take it out, drain it, and mix it with the meat waste in the kitchen waste Cut into meat strips with a length of 1.5cm; mix the bones separated from the animal waste with the bones in the kitchen waste and grind them into bone powder; soak the hair in an aqueous solution containing keratinase at a temperature of 60°C Under enzymatic hydrolysis for 3 hours, the enzymatic hydrolyzate was obtained and used for later use; the main component of feathers is keratin, and keratinase is a kind of pro...

Embodiment 3

[0091] The invention provides a method for preparing organic fertilizer from kitchen waste and animal and plant waste, comprising the following steps:

[0092] Step 1. Select the meat waste and bones in the kitchen waste, break or chop other waste in the kitchen waste, and set aside;

[0093] Step 2, smashing or chopping the plant-type waste, and set aside;

[0094] Step 3. After separating the meat, bones, blood and hair of the animal waste, cook the meat separated from the animal waste, take it out, drain it, and mix it with the meat waste in the kitchen waste Cut into meat strips with a length of 1.2cm; mix the bones separated from the animal waste with the bones in the kitchen waste and grind them into bone meal; soak the hair in an aqueous solution containing keratinase at a temperature of 50°C Under enzymatic hydrolysis for 2.5 hours, the enzymatic hydrolyzate was obtained and used for later use; the main component of feathers is keratin, and keratinase is a kind of pro...

Abstract

The invention discloses a method for preparing organic fertilizer with kitchen waste and animal and plant wastes; the method comprises the steps of classifying kitchen waste; crushing plant waste; chopping meat into 1-1.5 cm long meat strips; mixing and grinding bones into bone powder; soaking hair in keratinase solution, and enzymatically hydrolyzing to obtain enzymatic hydrolysate; mixing the mixture and a biological bacterial agent at a mass ratio of 100:(2-5), adding to a fermentation tank, fermenting, and filtering to obtain filter residue and filtrate; soaking a slow-release carrier in the filtrate, mixing well with the filter residue, and drying and crushing. The animal waste, kitchen waste and plant waste are used as materials, wastes are turned into wealth, environmental pollution is prevented, and nutrition of the fertilizer is more complete.

Description

technical field [0001] The invention relates to the technical field of fertilizers. More specifically, the invention relates to a method for preparing organic fertilizer from kitchen waste and animal and plant waste. Background technique [0002] Fertilizer is the food of plants and one of the material bases for improving agricultural production. Most of the existing fertilizers are chemical fertilizers or farmyard manures. Chemical fertilizers have single nutrients and are easy to lose, which will damage the soil structure and cause environmental pollution. Moreover, long-term use of chemical fertilizers will reduce the quality of crops and deteriorate the taste. The output of farmyard manure is low, it cannot be used in a large area, and it has been piled up in front of and behind the house for a long time. The natural fermentation time is long, which is easy to affect the sanitation of the rural environment, pollute the air, and easily cause the reproduction of harmful b...
