[0002] Stock garbage is not only complex in composition, but also large in quantity. It has accumulated over a long period of time into mountains, occupying a large amount of land, and with the continuous development and utilization of resources, its limit means that it needs to be carried out in a restrained manner. There are many resources in stock garbage that can be used again , but due to the difficulty of distinguishing and screening existing garbage, it is still impossible to realize the secondary utilization of effective resources in existing garbage
Although there are reports on the treatment process of mineralized waste in stock waste, due to the complexity of the equipment and the lack of order in the treatment process, the differential screening of mineralized waste has the defects of long time consumption and low efficiency, and there is no further plan for its resource utilization. Arranging and processing reasonable use

Embodiment 1

[0053] For the method of comprehensive treatment and resource utilization of stock garbage in this embodiment, please refer to figure 1 and figure 2 shown, including the following steps:

[0054] 1) Garbage excavation: The stabilized old landfill is excavated in a partitioned and layered manner;

[0055] 2) Convey the excavated mineralized waste to the vibrating plate screen through the feeder to remove the bulky waste, where the bulky waste includes building waste or large waste wood and other relatively large sizes The waste and old items then enter the first-stage drum screen, and the first-stage sieve, the part with a particle size > 80mm, then passes through the first magnetic separation equipment to magnetically screen out the metal substances doped in the material, and then enters the first wind separator The light materials such as plastics and fabrics obtained by winnowing are used to produce RDF, and the heavy materials enter the manual sorting platform to further...

Embodiment 2

[0070] The method for the comprehensive management and resource utilization of the stock garbage of this embodiment is basically the same as that of Embodiment 1, only the difference is: please refer to figure 1 and figure 2 As shown, the process flow of bio-organic fertilizer preparation from mineralized waste humus organic fine material is as follows:

[0071] A. Send the above-mentioned secondary sieve under matter mineralized garbage humus organic fine material, livestock and poultry manure, auxiliary materials, and composite microbial fermentation bacterial agent into the mixing mixer in specified weight parts, and stir and mix to make it uniform , to obtain mixed fermented material.

[0072] The raw material ratio is 25 parts by weight of mineralized waste humus, 25 parts by weight of livestock and poultry manure, 10 parts by weight of auxiliary materials, and 3 parts by weight of composite microbial fermentation agent;

[0073] The moisture content of the mixed ferme...

Embodiment 3

[0087] The method for the comprehensive management and resource utilization of the stock garbage of this embodiment is basically the same as that of Embodiment 1, only the difference is: please refer to figure 1 and figure 2 As shown, the process flow of bio-organic fertilizer preparation from mineralized waste humus organic fine material is as follows:

[0088] A. Send the above-mentioned secondary sieve under matter mineralized garbage humus organic fine material, livestock and poultry manure, auxiliary materials, and composite microbial fermentation bacterial agent into the mixing mixer in specified weight parts, and stir and mix to make it uniform , to obtain mixed fermented material.

[0089] The raw material ratio is 40 parts by weight of mineralized waste humus, 40 parts by weight of livestock and poultry manure, 25 parts by weight of auxiliary materials, and 8 parts by weight of composite microbial fermentation agent;

[0090] The moisture content of the mixed ferme...

Abstract

The invention discloses a method for comprehensively treating and recycling stacked rubbish. The method comprises the following steps: 1) digging rubbish; 2) sorting: adopting mechanical sorting and manual sorting, wherein mechanical sorting comprises first-level sieving and second-level sieving; the process is as follows: sieving and removing major rubbish by using a vibrating plate, entering into a first-level rotary screen, using a magnetic separator for removing secondarily used metal from the first-level oversize substances in grain size more than 80 mm and then entering into a first winnower, and winnowing, thereby acquiring light substances and first heavy substances, and then manually sorting the first heavy substances; pouring the first-level undersize substances in grain size less than or equal to 80 mm into a second-level rotary screen, manually sorting the secondary oversize substances in grain size more than 40 mm, using the magnetic separator for removing metal from the secondary undersize substances in grain size less than or equal to 40 mm and then entering into a second winnower, and winnowing, thereby acquiring the light substance used for preparing rubbish derivative fuel RDF and mineralized refuse humus used for preparing fertilizer. The method is capable of quickly and efficiently distinguishing and screening the mineralized refuse and realizing recycling rational utilization.
