Embodiment 1

[0091] The compost material fertilization process treatment method involved in the present invention comprises the following steps:

[0092] (1) After adjusting the moisture content, carbon-nitrogen ratio and PH value of the compost material according to the design formula of the fertilizer, uniformly mix the compost material by mechanical methods, and stack the mixed compost material into a stack with a width of 1.5 meters. , the stack height is 1 meter;

[0093] (2) Turn over the stacked materials from the third day for 6 consecutive days to increase oxygen supply and speed up the volatilization of water in the materials, mix the compost materials evenly and make the humidity value 50%rh ;

[0094] (3) Add any two of 20% of sawdust or chaff powder or mushroom debris or pearl waste powder to the compost material according to the percentage by weight, and simultaneously add 5.5% of plant ash and rice husk ash as fermentation material; make the compost material Carry out a fe...

Embodiment 2

[0097] The compost material fertilization process treatment method involved in the present invention comprises the following steps:

[0098] (1) After adjusting the moisture content, carbon-nitrogen ratio and PH value of the compost material according to the design formula of the fertilizer, uniformly mix the compost material by mechanical methods, and stack the mixed compost material into a stack with a width of 3.5 meters. , the stack height is 2 meters;

[0099] (2) Turn over the stacked materials from the third day for about 8 days to increase the oxygen supply and speed up the volatilization of water in the materials, mix the compost materials evenly and control the humidity to 70% rh;

[0100] (3) Add 50% of any three of sawdust or chaff powder or mushroom debris or pearl waste powder to the compost material by weight percentage, and add 4.5% of plant ash or rice husk ash as fermentation material at the same time; make the compost material A fermentation is carried out t...

Abstract

The invention relates to a domestic wet garbage composting treatment device and a treatment method for preparing a fertilizer from domestic wet garbage, which comprises a wet garbage raw material unloading mechanism, a wet garbage raw material loading and feeding mechanism, a wet garbage raw material selection and wet garbage coarse material belt conveying mechanism, a wet garbage coarse material pulverizing mechanism, a first wet garbage fine material belt conveying mechanism, a wet garbage fine material dehydrating mechanism, a fermentation material and bacterium material adding mechanism, a second wet garbage fine material conveying mechanism, a wet garbage fine material stirring mechanism and a composting material loading mechanism, wherein the adjacent mechanisms are connected into a complete plant capable of integrally synchronous automatic operation through a plurality of belt conveyors arranged at intervals. The method comprises the following steps: selecting the wet garbage raw material to obtain the coarse material, pulverizing the wet garbage coarse material to obtain the wet garbage fine material, carrying out dehydration treatment on the wet garbage fine material, adding the fermentation material and bacterium material, stirring, and sending to the fertilizer preparation technique. The complete device can implement synchronous automatic operation, has the advantages of high work efficiency, low labor cost and favorable composting effect, utilizes the wastes, and changes wastes into valuable substances; and the fertilizer satisfies the national industry standard.

Description

technical field [0001] The invention belongs to the technical field of domestic garbage disposal, relates to the fertilization treatment of domestic wet garbage, and particularly relates to a compost treatment device for domestic wet garbage and a fertilizer treatment method thereof. Background technique [0002] On the earth inhabited by human beings, domestic garbage will be produced every minute and every second. With the progress of human beings, especially the improvement of living standards and quality of life, the generated domestic garbage is increasing day by day. For the dry garbage in the domestic garbage, in addition to being recycled and reused, the rest of the dry garbage can be disposed of by landfill or incineration. [0003] As for the treatment of wet garbage in domestic garbage, my country is still at the stage of digging and landfilling. Since most of the wet landfills only use simple landfill disposal methods, the environmental management in the dispos...
