Method for producing an environment-friendly enzyme organic fertilizer

Abstract

The invention discloses a method for producing an environment-friendly enzyme organic fertilizer from kitchen waste, and belongs to the field of waste treatment. The process sequentially comprises the following steps: (1) preparing raw materials including brown sugar, the kitchen waste and water; (2) mixing the brown sugar and the water in a ratio and putting the mixed brown sugar and water in an airtight container with a cover, and uniformly stirring; (3) placing the kitchen waste in the mixed sugar solution in the step (2), uniformly stirring, and adequately mixing with the sugar solution to obtain a mixed solution; (4) adjusting the pH value of the mixed solution to 4-6 by a citric acid solution; (5) adding a strain, and uniformly stirring; (6) hermetically carrying out anaerobic fermentation for 3-6 months; (7) adding a stabilizer sodium chloride, and adequately and uniformly mixing to obtain a high-quality organic fertilizer; and (8) filtering the high-quality organic fertilizer, wherein supernatant is a liquid enzyme, and filter residue is an enzyme residue. In the method disclosed by the invention, the kitchen waste is used as a fermentation raw material, the fermentation speed is high, the yield is high, the yield of organic fertilizers is high, the operation is convenient and easy, and the environment friendliness is realized.

Description

technical field [0001] The invention belongs to the field of garbage treatment, in particular to a method for making environmentally friendly enzyme organic fertilizer by using kitchen waste. Background technique [0002] Enzyme (enzyme) is actually an old translation of enzyme. Enzymes are biomacromolecules with biocatalytic functions, namely biocatalysts, which can accelerate the speed of biochemical reactions, but do not change the direction and products of the reactions. Environmentally friendly enzyme organic fertilizer is a high-quality organic fertilizer produced by using fresh kitchen waste in daily life through anaerobic fermentation. It contains a large number of probiotics and enzymes, which can be used for the production of pollution-free, green and organic agricultural products. Environmentally friendly enzyme organic fertilizer is produced by microbial fermentation of domestic fresh garbage under anaerobic conditions. Because it is carried out in a closed env...

Problems solved by technology

However, there are also the following disadvantages: 1. Natural fermentation, with various types of microorganisms, and the direction of the fermentation process is uncertain; 2. The growth of microorganisms requires a certain pH range, and it takes a long time to naturally adjust the pH value; 3. In the storage process If the storage time is too long, there will be over-fermentation or over-acidification, which will affect the quality of organic fertilizer.

However, this patent requires oxygen to be fed into the container, which not only increases the production cost, but also causes more acetic acid to be decomposed into CO 2 and water, resulting in waste of nutrients, reducing the quality and yield of organic fertilizer
