Abstract
The present invention provides a kind of method of the disposal of human lives' rubbish with recycling, and comprises the following steps：1）, by being screened by bounce screen, be heavy substance and screenings, 2 on the upper light materials of sieve, sieve by screening rubbish）After the upper light materials progress second-time breakage of sieve, twice pressing dehydration, gains are subjected to RDF making；The upper heavy substance of sieve is sorted residue being transported to after magnetic separator goes out to be sorted first residue is subjected to RDF making；Screenings is subjected to press dewatering, the solid matter after press dewatering is subjected to secondary sorting through secondary sorting sieve, secondary oversize matter is screened through magnetic separator, after nonmetallic substance progress second-time breakage, twice pressing dehydration, gains are subjected to RDF making.The inventive method need not build fermenting cellar pond and Zymolysis Equipment, environmentally friendly, be especially suitable for city construction, relatively few because investing, and be more suitable for setting up middle-size and small-size garbage disposal plant in Small Urban.
Description
Technical field
The present invention relates to waste resources recycle utilization technology field, specially a kind of disposal of human lives' rubbish and profit again
Method.
Background technology
With the continuous improvement of living standards of the people, the species of rubbish the increasing increasingly with quantity, to the processing side of rubbish
Formula also develops constantly, and the especially recycling to rubbish turns into the development main trend of garbage disposal, but to rubbish
The exploitation of the practicality and popularization of the methods of rubbish processing is even more the task of top priority.
Realize that the recycling of rubbish first has to classify to rubbish, although advocate people to abandoning in China at present
The dynamics of refuse classification is being strengthened, but people still seldom or without this custom remove the mark by dustbin in real life
Know the classification felt, therefore to change this state or very long.There is no good sorting rubbish will be to garbage disposal
System is an acid test, but advanced investment this operating mode that big equipment can not be adapted to completely again, and equipment again
Investment necessarily tool is big, therefore human assistance is also an essential part at present.
Current developing countries many in the world, due to technology and fund reason, its garbage disposal is still continued to use traditional
Landfill, compost, incinerating method, it is many such as to there is disadvantage in these three methods：1st, landfill method：Abandon using thing, taken up an area and greatly may be used
For ground is fewer and fewer, secondary pollution is serious, transport landfill administration fee is big.2nd, composting process：Take up an area big, cycle length, environmental sanitation
Difference, fertilizer efficiency are low, cost is not also small.3rd, burning method：Burn available resources, burning and produce harmful exhaust purification cost height, ash
Slag also brings along secondary pollution.Three of the above method is all directly handled rubbish without pre-selection, therefore its disadvantage is aobvious and easy
See.
In addition research and development is exactly garbage derivatived fuel (Refuse Derived Fuel) energetically both at home and abroad at present
Technology, it is that house refuse is first carried out effectively pretreatment and processing and forming by one kind, is then incinerated profit as solid fuel
Garbage derivatived fuel（Abbreviation RDF）, this method is commonly used in garbage disposal.
The content of the invention
Technical problem solved by the invention is a kind of method of the disposal for providing human lives' rubbish with recycling, with
The problem of solving in above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme：A kind of disposal of human lives' rubbish with
The method of recycling, comprises the following steps：
1）, by chain mat machine bagged garbage be transported to bag-breaking machine carry out broken bag processing, sieved afterwards by bounce screen
Choosing, is heavy substance and screenings on the upper light materials of sieve, sieve by screening rubbish, and wherein screenings accounts for the 25~40% of rubbish gross mass,
Heavy substance accounts for light materials on the 20~30% of rubbish gross mass, sieve and accounts for the 25~40% of rubbish gross mass on sieve.
2）, gains will be subjected to RDF making after the upper light materials of sieve carry out second-time breakage, twice pressing dehydration；Will sieve
It is big metalwork, big fruits and vegetables skin and masonry block that upper heavy substance carries out sorting first, and residue is transported at magnetic separator and divided
Material after choosing, magnetic separator is carried out after second-time breakage, twice pressing dehydration, and gains are carried out into RDF making；By screenings
Press dewatering is carried out, waste liquid is added press filtration water squeezing is carried out after water treatment agent, obtained solid matter is used for by fertilizer processed
Trees are afforested and flowers and plants, by obtained water normal discharge up to standard, by solid matter under the sieve after press dewatering again through secondary sorting
Sieve carries out secondary sorting, will transport outward fill after secondary screenings matter deodorization afterwards, secondary oversize matter is screened through magnetic separator, will
Metallics recycling, nonmetallic substance are carried out after second-time breakage, twice pressing dehydration, and gains are carried out into RDF making.
The metalwork is sent to salvage station and reclaimed, and big fruits and vegetables skin organic matter send fertilizer producing plant to recycle, masonry block warp
Landfill factory landfill is sent after deodorization processing.
Compass screen surface sieve mesh selected by the bounce screen is 60~90mm.
The compass screen surface sieve mesh of the secondary sorting sieve is 20~40 mm.
The RDF manufacture crafts include：Heating, RDF shapings and cooling and shaping product.
Compared with disclosed technology, there is advantages below in the present invention：
1st, the inventive method need not build fermenting cellar pond and Zymolysis Equipment, so invest, take up an area, the cycle can all have improvement greatly.
