Abstract
The invention discloses a kind of domestic waste separating and recovering methods, it is that rubbish is poured into channel using water as power, it is equipped with one group of shredder in channel to tear bagged garbage, then using floating precipitation method separation, density in rubbish is greater than water with water and is separated less than the substance of water；The substance for being greater than water for density, using Multistage settling method and suspension partition method, separates metal, glass, stone, plastics in settling tank and suspension separate tank, remaining substance is sent to ferment into methane-generating pit using water as fluid；Be less than the substance of water for density, after dehydration, drying and processing, using pneumatic concentration by foam, film, paper, fiber separation, remaining substance is sent into sweathouse and ferments, and is sent into sedimentation basin after plastics being filtered out by filtering.The present invention has method simple and easy；Treating capacity is big, and separative efficiency is high；It is at low cost, high financial profit.
Description
Technical field
The present invention relates to a kind of domestic waste separating and recovering methods.
Background technique
Refuse classification method is generally after broken, screening, sorting, magnetic separation at present, then carries out fermentation process.Due to rubbish
The particularity of composition, the processing method are suitable for ore dressing, and for rubbish, just seem inefficiency.
Summary of the invention
Present invention aim to provide a kind of waste disposal method that the efficiency of separation is high.
Realize the scheme of the object of the invention are as follows:
Rubbish is poured into channel using water as power, one group of shredder is equipped in channel and tears bagged garbage, then using floating
Density in rubbish is greater than water with water and separated less than the substance of water by precipitation method separation.It is greater than the substance of water for density, with
Water makes metal, glass, stone, plastics in settling tank and suspension point as fluid using Multistage settling method and suspension partition method
From separating in pond, remaining substance is sent to ferment into methane-generating pit.It is less than the substance of water for density, after dehydration, drying and processing,
Using pneumatic concentration by foam, film, paper, fiber separation, remaining substance is sent into sweathouse and ferments, by filtering plastics
Sedimentation basin is sent into after filtering out.
The present invention has the advantages that
1, method is simple and easy；
2, treating capacity is big, and separative efficiency is high；
3, at low cost, high financial profit.
Specific embodiment
Rubbish is poured into channel using water as power, one group of shredder is equipped in channel and tears bagged garbage, is then sent
Enter to float precipitation and separation pond, the substance that density is greater than water enters level-one settling tank by floating precipitation and separation pond lower part.Adjustment sedimentation
The flow velocity of water makes the faster metal of the larger sinking speed of density, glass, stone be separated, into suspension separate tank,
Remaining substance enters second level settling tank.Adjustment, which suspends, separates the upward flow velocity of water, and the substance for keeping density different is gradually suspended in
It is separated in water, is sent into sedimentation basin if a small amount of sundries such as pericarp, dish bits.It is separated in second level settling tank
Pericarp, dish bits are sent into sedimentation basin, remaining substance is then re-fed into sedimentation basin after silk screen filters out plastics, heavy in sedimentation basin
Starch is sent into methane-generating pit processing.The substance that density is less than water enters floating pool by floating precipitation and separation pond top, in floating pool
Floating material is ceaselessly scraped the water surface and is sent into dehydrator dehydration, is then fed into dry by the netted scraper plate equipped with one group by chain drive
Dry room is dried, and carries out selection by winnowing to the substance after drying using blower, plastic film and foamed material are isolated
Come, processing is then further dried again, is separated waste paper with same method, remaining substance is sent into sweathouse and is carried out
Then fermentation process uses filtration method, the difficult decaying material such as blocky plastics is separated, remaining substance is sent into sedimentation basin.
Claims (1)
1. a kind of domestic waste separating and recovering method is that rubbish is poured channel using water as power, one is equipped in channel
Group shredder tears bagged garbage, then using floating precipitation method separation, with water by density in rubbish greater than water and less than water
Substance separation；The substance for being greater than water for density, using Multistage settling method and suspension partition method, makes gold using water as fluid
Category, glass, stone, plastics separate in settling tank and suspension separate tank, remaining substance is sent to ferment into methane-generating pit；For close
Degree is less than the substance of water, through dehydration, after drying and processing, using pneumatic concentration by foam, film, paper, fiber separation, remaining substance
It is sent into sweathouse to ferment, is sent into sedimentation basin after filtering out plastics by filtering.
