Description
Technical field
The present invention relates to environmental technology field, more particularly to a kind of method of Waste sorting recycle processing.
Background technology
With expanding rapidly for China's sustained and rapid development of economy and urbanization, China's house refuse annual output at this stage
More than 1.5 hundred million tons, the house refuse thus brought is piled up arbitrarily, a large amount of appropriation of land, environmental pollution is serious, harmful to human is strong
The problems such as health, resource largely waste, it has also become influence environmental protection and an important factor for sustainable development.
The processing house refuse overwhelming majority is using the methods of landfill, burning, compost at present, from resource circulation utilization
Angle is seen, the requirement that house refuse does not meet sustainable development is handled to fill, in a manner of burning, and China's house refuse is most of
All it is non-classified rubbish, has the characteristics that moisture content height, calorific value is low, ingredient is miscellaneous mostly, the process directly burned may
Many foul gas are generated, this mode both had seriously polluted the environment, and was wasted again during landfill a large amount of renewable or again
The resource utilized again.In domestic waste, plastics, glass, metal, kitchen garbage etc. are renewable or recycling money
Source can walk the road of " sustainable development " by being recycled after classification and sorting.China advocates house refuse and carries out at present
Original-source by classification is fundamentally realized " minimizing, the innoxious, recycling " of domestic waste, but China's domestic rubbish disposal
Caused problem does not carry out garbage classification sorting mainly due to house refuse complicated component, causes single mode not applicable
In composting, along with China's laws and regulations are unsound, resident generally realizes the reasons such as not high, life garbage original-source by classification
Method implements extremely difficult.Therefore, it is necessary to be pre-processed to rubbish, i.e. sorting before garbage disposal, improve reliable
Sorting consumer waste technology is the key that improve rubbish sustainable use, realize comprehensive management of technology.

It is divided into dregs glass, these processing modes of dregs glass after crushing are similar with screenings processing mode recited above, than
Great material can sink under water, these heavy materials are essentially all wood materials, be used as fuel after dehydration and drying, water
Be discharged into after the filtrate flocculation sediment that generates after power sorting sewage treatment plant it is up to standard after discharge, for the sludge that flocculation sediment generates,
It can be mixed into the raw material of cement brick and burned brick, wherein inorganic salts can be as the filler of brick after firing, and organic matter can
Using the fuel as sintering procedure, thermal energy has been made full use of.
Selection by winnowing in step (7) refers to that the light material in step (6) is sent into domestic garbage comprehensive winnowing machine, passes through control
The light refuse of different densities is divided into organic matter, paper and plastics and textile fabric by wind speed size processed, and organic matter is used for compost, paper
And plastics recycling, textile fabric are recycled by break process at textile fabric.
Operation principle：After being handled by bag-breaking machine broken bag, solid refuse is obtained, obtained solid refuse is sent to conveyer belt
Divide and carry out ragging by picking equipment, the recoverable material of bulk and unclassified stores is sorted out, wherein bulk metal, paper
Box, Bottle ＆ Can are recycled according to existing technology and different property, and the material of other bulks is mainly concrete block
It can be recycled as filler, road-making material or brickmaking after broken；After ragging it is remaining be compared with
The solid refuse of smaller piece is further carried out magnetic sorting with electromagnet, isolates the magnetism such as metal by the solid refuse of fritter
Material, metal are used as metallurgical raw material；Solid refuse after magnetic sorting is subjected to screening sorting, can be separated on screenings and sieve
Object, screenings are mainly tiny dregs, are used directly for filler, brickmaking etc., oversize is further sorted by whirlpool electricity
Machine isolates non-magnetic conductor metal and nonmetallic materials, and wherein non-magnetic conductor metal is mostly copper, aluminum products etc., can be classified
Recycle or make copper aluminum composite material；Nonmetallic materials are sent to water scalping tank, can be made by the ascending current of agitation
The material of different densities floats to above with water, successively sorts out light material, middle matter material and heavier feeds, heavy object
Material is mainly wooden fuel, fuel is used as after being handled by dehydration and drying, middle matter material is mainly dregs and glass, passes through dehydration
It is used as construction material after drying, light material is divided into organic materials, paper and plastics and textile fabric, organic materials master after sorting
If rubbishes from cooking such as vegetables, divide organic matter rich in abundant, compost can be used for and make fertilizer, paper and plastics can be granulated back
Receive, textile fabric by being recycled after being broken into textile fabric, the filtrate generated after wet concentration be discharged into Sewage Disposal handle it is up to standard
After discharge.
