Abstract

The invention discloses a construction waste treating and recycling method. The method comprises the following steps: (1) properly smashing construction waste through a smasher, and initially sorting in a manual and/or mechanical way; (2) performing first-stage smashing and magnetic separation on remaining materials, sorting out small-piece metal materials, adding water into the materials for cleaning, and performing flotation to sort saw dust and small-piece plastic parts out; (3) performing second-stage smashing on the materials treated in the step (2) to generate aggregate for use in subgrade pavement; (4) screening burnt dust slag, separating powder and stone particles out, adding a certain amount of curing agent into the obtained powder, and performing conventional treatment to obtain cement. By adopting the method, the comprehensive utilization ratio of construction waste can be increased fully and effectively, and environmental pollution caused by construction waste is lowered.

Description

Building waste is processed recoverying and utilizing method
Technical field
The present invention relates to construction waste processing technology field, specifically belong to building waste and process recoverying and utilizing method.
Background technology
At present, unprocessed being connect of most building wastes transports suburb stacking to, taken a large amount of industrial lands, and as being located in reason not as good as timeliness and utilizing, the contradiction of its appropriation of land can be more and more serious.In addition, building waste is being stacked field after rainwater sprinkling, the a large amount of afwillites and the calcium hydroxide that in waste mortar and concrete block, contain, the a large amount of sulfate ions that contain in waste gypsum, the plurality of heavy metal ion stripping containing in old metal, there is anaerobic degradation generation lignin and tannic acid and resolve into organic acid in waste paperboard and culled wood self simultaneously, the leakage water producing so is generally strong basicity and contains a large amount of heavy metal ion, hydrogen sulfide and a certain amount of organic matter are controlled and inflow Jiang Hai if do not added, lake or the infiltration end, ground, can cause earth's surface and underground water pollution directly to endanger aquatic organism existence and water resource utilization.Moreover, waste gypsum in building waste contains a large amount of sulfate ions, under anaerobic can be converted into the hydrogen sulfide gas with rotten-egg odour, there is anaerobic degradation and produce lignin and tannic acid and resolve into organic acid in waste paperboard and culled wood self, and these pernicious gases can severe contamination atmosphere.The harmful substance of the above-mentioned generation of contaminated soil produces and pollutes soil, affects nutrient absorption and the growth of plant, the ecological balance of spoiled soil inside.Therefore, the processing of building waste is very urgent.
Summary of the invention
Having the object of this invention is to provide building waste and processed recoverying and utilizing method, can fully effectively improve the comprehensive utilization ratio of building waste, reduced the pollution of building waste to environment, allowed rubbish produce economic benefit, is the key that solves building waste.
Building waste is processed recoverying and utilizing method, comprises the following steps:
1) first building waste is undertaken after suitable fragmentation by disintegrating machine, through artificial and/or mechanical system, large part metal species, Plastic, glass sorting are wherein picked, large part metal species, Plastic, glass processing and utilizing again;
2) remaining material is carried out to one-level fragmentation, magnetic separation, the metal species material of smallclothes is selected, in add water cleaning, flotation of material, wood chip and working of plastics smallclothes are sorted out, wood chip and plastics smallclothes can be used for boiler combustion heating and then surplus material are poured into incinerator burning, and the heat energy obtaining generates electricity for generator; Smallclothes metal can melt down utilization;
3) material after treatment second step is carried out to two-stage crushing regeneration aggregate, lay for roadbed.
4) the dirt slag after burning is sieved, isolate powder and stone particle; In the powder obtaining, add some curing agent, after conventional treatment, make cement;
The percentage by weight of the each component of described cement is: powder 75~85%, curing agent 15~25%.
Described fixing agent is that calcium sulfate, sodium chloride, calcium chloride, carbonic hydroammonium, potash, sodium carbonate, purified water are mixed with into.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention can fully effectively improve the comprehensive utilization ratio of building waste, reduces the pollution of building waste to environment, allows rubbish produce economic benefit, is the key that solves building waste.
Detailed description of the invention
