Description
Technical field
The invention belongs to aging waste reutilization technical fields, are related to a kind of side manufacturing concrete using aging rubbish
Method.
Background technology
Since the 1970s, China gradually starts using burying method processing disposition domestic waste.So far
Landfill has become the main disposal options of China's domestic waste, and the domestic waste of disposition is handled using burying method
Amount accounts for about 70% or more of whole treating capacities, and built multiple large-scale landfills insert several ten million tons of rubbish.Since health is filled out
The method of burying has the advantages that with good investment, simple for process, management is convenient, applied widely, maintenance cost is low etc., according to China's economic technology
Horizontal and domestic waste forms situation, and within longer one period from now on, China's Disposal of City Domestic Garbage will be to fill out
Based on burying.
Disposition house refuse is handled using landfill method and still faces several big outstanding problems：First, the yield of house refuse is every
Year is increased sharply with 7% -9% speed, and the area of required landfill yard is increasing；Second is that city range is constantly to surrounding area
Extension, suburbs land price escalate, and keep the addressing of landfill yard more and more difficult, or even can not find suitable site, huge
Municipal Garbage Yield is contradicted with the land resource of growing tension；Third, after China's the 70's of 20th century especially in the 8O ages after
A large amount of refuse landfills that phase builds have reached or are up to service life, and landfill yard builds and recycle problem to become again
It obtains more and more sharp.Especially a large amount of informal landfills make ambient air, soil, water body and resident living environment
At negative effect, while occupying a large amount of valuable land resources.Therefore, the control of the aging rubbish of refuse landfill is compeled
In the eyebrows and eyelashes.
Currently, the recycling for aging rubbish, be broadly divided into it is several under it is several, first, out waste and old filtered out
Plastics are used for regenerating raw materials for plastics production, second is that the combustible of screening is used for being converted to fuel gas, third, the brick stone of screening
Block is used for that hollow brick is made.In aging rubbish, the quantity of brick stone is fewer, is original with queen closer or stone
Hollow brick is prepared, there are problems that starving；Also, current technique can only prepare hollow brick, and type is single and empty
The intensity of heart brick is excessively poor.And house refuse is after the aging process of 8-10, most of substance corruption is this at humus
Humus in addition to can be used for improveing soil, build up fields organic fertilizer is made other than without better purposes, be even manufactured into organic fertilizer,
It is also required to special fermentation installation, not only occupies a large amount of soil, and cost is relatively high.
Invention content
The present invention proposes a kind of aging rubbish of novel utilization for the problem of traditional aging garbage processing procedure
The method for manufacturing concrete.
In order to achieve the above object, the present invention is realized using following technical solutions：
A method of concrete being manufactured using aging rubbish, is included the following steps:
