Abstract

The invention discloses a method for preparing organic fertilizer by utilizing kitchen garbage. The method comprises the following steps: (1) separating and crushing; (2) filtering to remove floatingoil; (3) performing the enzymolysis treatment; (4) separating oil; (5) performing the primary fermentation; (6) performing the secondary fermentation; and (7) granulating. The method for preparing theorganic fertilizer by utilizing the kitchen garbage is simple in process, and low in cost; and moreover, the vegetable oil and animal fat in the kitchen garbage can be effectively removed, the nutrition ingredients in the kitchen garbage can be effectively recycled and made into the organic fertilizer with good fertility, and the environmental pollution problem of the kitchen garbage can be solved.

Description

technical field

[0001] The invention relates to the technical field of garbage recovery, in particular to a method for preparing organic fertilizer from kitchen garbage. Background technique

[0002] Food waste includes leftover food residues, melon peels, and fruit scraps left over from eating every day; vegetables, leftovers, leftover bones, etc. after choosing vegetables, washing vegetables, and washing dishes. For this kind of kitchen waste, it is generally put into garbage bags and thrown away directly. In the urban waste treatment system, most of them are disposed of by landfill and incineration, which not only pollutes the environment, but also cannot be recycled. There are also households or restaurants to install garbage disposers, which are generally connected to the water outlet of the pool. The garbage flushed from the pool enters the garbage disposer. The treatment method is likely to cause blockage of the urban sewer system, and it is also easy to breed bacter...

Examples

Embodiment 1

[0030] A method for preparing organic fertilizer from kitchen waste, characterized in that it comprises the following steps:

[0031] (1) Sorting and crushing: Sorting the kitchen waste, sorting out the organic matter and removing the sundries in the kitchen waste that cannot be made into fertilizers, and then crushing the sorted organic matter to obtain organic waste particles with uniform particle size The mixture, at this time, the oil content measured by the instrument is 350mg / L; wherein, the sundries that cannot be made into fertilizers include metal sundries, glass sundries, plastic sundries, wooden sundries, dust and stone sundries;

[0032] (2) Filtration to remove oil slicks: After the mixture of organic waste particles was allowed to stand for 3 hours, filter to remove the upper layer of oil slicks to obtain organic waste particles;

[0033] (3) Enzymolysis treatment: add compound enzyme to the organic waste particles in step (2), and carry out enzymolysis treatment...
