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...
