Description
Technical field
The utility model relates to landfill waste processing technology fields, more particularly to a kind of interior circulation rubbish separation system.
Background technique
Currently, most of garbage disposal accounts for about 70% or more of whole treating capacities based on filling.World's majority state,
Especially most garbage disposals of undeveloped country use the method.Its main feature is that: construction and operating cost are lower, operation letter
Single, treating capacity is big.But there is also many drawbacks: first is that occupying a large amount of soils, addressing is difficult, and soil sign dials expense
It is high；Second is that wasting a large amount of rubbish includes resource, rubbish is artificially turned into " resource that cannot increase, the huge wealth thrown away
It is rich ", recycling treatment demand is not achieved；Third is that environmental pollution is serious, filled out because health is not achieved mostly in the construction of existing landfill yard
The requirement buried, the bacterium object in rubbish constantly seep downwards drip, polluted soil and water quality, and with the increase of accumulating amount and time
Continuity, pollute and spread to periphery and underground deep layer, left troubles to thousand, poison that rubbish is distributed, odour are dispersed to surrounding, are formed
In the air, periphery, underground stereo pollution.Although in a small number of " health of some more developed urban construction of many developed countries and China
Landfill yard " reduces some pollutions, but as technical not perfect and caused by problem of environmental pollution it is still very much, cannot
It tackles the problem at its root.
With the continuous improvement of living standards, the plastics in landfill waste are not degradable, it is difficult to handle, environmental pollution is tight
Weight, therefore, be recycled to landfill waste particularly significant.There is presently no be recycled specifically for landfill waste
Device, garbage disposal separation system on the market can not adequately be handled the recyclable rubbish in landfill waste, together
Shi Yunhang is at high cost, and garbage classification is not thorough, and needs to carry out secondary sorting, and increase cost treatment effeciency is low, influences to landfill rubbish
