Embodiment 1

[0020] Turn on the crusher 2, pour the household garbage into the hopper 1 and fall into the separation pool 3 after being crushed by the crusher. After all the garbage is broken, spray clean water on the surface of the separation pool to make other substances adhered to the surface of the floating objects enter the water and start floating. Object collector 12, floating object is collected, sprays clear water to the floating object of collecting with sprinkler 8 and other matter on the floating object is cleaned, and the floating object after cleaning is packed in the first collecting container 4; Open drain Liquid port 10, put the liquid part in the separation tank into the biogas digester 7; start the conveyor 5, transport the sediment at the bottom of the separation tank to the sieving machine, start the sieving machine 13, wash and sieve the sieve, and Part of the collection is loaded into the second collection container 5, and after the sediment at the bottom of the pool ...

Embodiment 2

[0022] Turn on the crusher 2, pour the household garbage into the hopper 1 and fall into the separation pool 3 after being crushed by the crusher. After all the garbage is broken, spray clean water on the surface of the separation pool to make other substances adhered to the surface of the floating objects enter the water and start floating. The object collector 12 collects the floating objects, sprays clear water on the collected floating objects to clean other substances on the floating objects, and packs the cleaned floating objects into the first collection container 4; starts the conveyor 5 to separate The sediment at the bottom of the pool is transported to the sieving machine, the sieving machine 13 is started, washing and sieving is carried out, the part on the sieve is collected and put into a collection container, the liquid discharge port 10 is opened, and the liquid part in the separation tank is put into the biogas digester Step 7: When the sediment at the bottom o...

Abstract

The invention relates to a domestic garbage classification processing method and a classification device thereof, and belongs to the technical field of environmental protection. The method comprises the following steps: garbage is crushed and then is added into the water of a separating pool; in the garbage, substances which have specific gravity less than that of water and are hydrophobic float on the water to form floating matters, substances which have the specific gravity larger than that of water precipitate to bottom to form precipitates, and substances which are closed to water in specific gravity or hydrotropic substances are suspended in the water to form suspended matters; the floating matters are cleaned and then are processed in a centralized sorting mode, the precipitates are screened, the precipitates above a sieve are cleaned and then sorted, and the precipitates below the sieve precipitates and then directly buried; the suspended matters and water are subjected to anaerobic fermentation to produce biogas. The classification device comprises a hopper, a crusher, the separating pool, a first collecting container, a second collecting container 5, a sedimentation basin and a biogas digester. The method and the device have the advantages that the investment of the processing device is greatly reduced, the operation is convenient, and 50-90 percent of transportation cost of garbage is reduced.

Description

technical field [0001] The invention relates to a treatment method for solid waste, in particular to a domestic waste classification treatment method and a classification device thereof, belonging to the technical field of environmental protection. Background technique [0002] The domestic garbage in urban living quarters is mostly solid waste generated by ordinary residents in daily life, mainly including waste paper, plastic, metal, glass, ceramics, dust, food waste, etc. Due to the complex composition of these solid wastes, it is difficult to collect At present, unified recycling basically adopts two methods of landfill and incineration. These treatment methods have insurmountable defects. For many large and medium-sized cities, it is difficult to find suitable landfill sites; for incineration, the construction and operation costs of incineration facilities are relatively high, and there is still smoke pollution, although people are constantly developing new ones. Incin...
