Description
Technical field
The present invention relates to a kind of processing method of garbage, specifically a kind of solid waste stacks the innoxious place in field
Reason method, it is innoxious that more particularly to a kind of solid waste for including heavy metal residue and noxious chemical wastess stacks field
Processing method.
Background technology
At present, due to industrialization and urbanization, the solid waste such as produced many industrial refuses, house refuse is stacked
In the periphery in factory, mine or city.As the country does not carry out mandatory classifications to rubbish, there is no the custom of refuse classification yet,
Therefore, solid waste mixes metallic residue emphatically and poisonous chemical waste in being particularly Mine Solid Wastes unavoidably,
Pile up on soil surface, destroy soil, natural landscape and the vegetation of earth's surface, soil erosion aggravation is caused seriously to ecological environment
Destruction, and content of beary metal and chemical agent in solid waste are more, cause severe contamination to surface water and groundwater.Mesh
Before, it is general using process or reclaim process or the landfill disposal of banking up(Brief talk the process of Mine Solid Wastes and created using science and technology
2013. № .02 environmental sciences P146 of new Leader).
The content of the invention
It is an object of the invention to provide a kind of solid waste stacks field method for innocent treatment.
The present invention is adopted the following technical scheme that and realizes its goal of the invention, and a kind of solid waste stacks field ecological recovery
Method, it comprises the following steps:
(1) the solid waste in field will be stacked to mix homogeneously with fixative and water, compacting is rolled;
(2), in compacting process, the center for making stacking field is high point, and with 5 ° of < gradients <, 45 ° gradually incline to periphery;
(3) impervious barrier is placed in solid waste after compaction, the clay that thickness is 10 ㎝~20 ㎝, pressure are stacked on impervious barrier
It is real;
To avoid impervious barrier from moving in solid waste, the present invention step (3) in, solid waste first after compaction
It is upper to stack the clay that thickness is 10 ㎝~20 ㎝, compacting;Impervious barrier is placed again, stacks thickness again for 10 ㎝~20 ㎝ on impervious barrier
Clay, compacting.
(4) the sand bed that thickness is 1 ㎝~3 ㎝, compacting are stacked on clay after compaction.
Impervious barrier of the present invention is non-woven fabrics or waterproof blanket.
Due to adopting above-mentioned technical proposal, the present invention preferably to realize goal of the invention, to solid waste by middle height,
The low design implementation of periphery is smooth and rolls, and one is to reduce the space that solid waste is occupied;Two is using embedding nothing in clay
Cloth or waterproof blanket closing solid waste are spun, rainwater is flowed downward out along the inclined-plane that solid waste is constituted, and effectively prevents rainwater
Penetrate in solid waste, so as to prevent solid waste because rainwater infiltration pollutes thing dissolves in rainwater and outside seepage expansion
Dissipate;Three is that fixative is added with solid waste, can be under conditions of no rainwater waters down, by chemical reaction and attachment
Function reduces the activity of chemical pollutant and heavy metal element.
Description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Fig. 2 is the structural representation of the embodiment of the present invention 2.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment 1:
As shown in Figure 1, a kind of solid waste stacks field ecological recovery method, and it comprises the following steps:
(1) the solid waste in field will be stacked to mix homogeneously with fixative and water, compacting is rolled;
(2), in compacting process, the center for making stacking field is high point, and with 5 ° of < gradients <, 45 ° gradually incline to periphery;
(3) impervious barrier is placed in solid waste after compaction, the clay that thickness is 10 ㎝~20 ㎝, pressure are stacked on impervious barrier
It is real;
(4) the sand bed that thickness is 1 ㎝~3 ㎝, compacting are stacked on clay after compaction.
Impervious barrier of the present invention is non-woven fabrics or waterproof blanket.
The present embodiment is first mixed homogeneously with fixative and water to stacking the solid waste 1 on field, implements to grind with mechanization
Pressure compacting, in compacting process, the center for making stacking field is high point, is inclined to periphery gradually from high point with 10 ° of the gradient.
The fixative is a kind of chemical fixatives repaired for heavy-metal contaminated soil disclosed in the patent No. 201310224997.4.
Using when, solid waste 1:Fixative:The ratio of water is 100:(4~6):(30~50).
Impervious barrier 3 is placed in solid waste 1 after compaction, the clay 2 that thickness is 20 ㎝, pressure on impervious barrier 3, is stacked
It is real;Impervious barrier 3 selects non-woven fabrics.
The sand bed 4 that thickness is 3 ㎝, compacting are stacked on clay 2 after compaction.
To reach the purpose for stacking field ecological recovery, the present invention can also 30 ㎝ of laying depth above of sand bed 4 after compaction
Cultivation soil 5, plants upper grass Seedling 6 on cultivation soil 5.
Soil 5 is cultivated described in the present embodiment includes clean soil, organic matter, fertilizer, water-retaining agent, stabilizer, acidity regulator
And disinfectant, by a certain percentage mixture form(By weight).Clean soil takes unpolluted soil, and organic matter adopts straw stalk
Or rice straw or wood fiber powder are broken into 10 ㎜~15 ㎜, fertilizer adopts quick-acting chemical fertilizer and slow chemical fertilizer, increases barren side slope fertility, carries
For the nutrition required for plant growing, water-retaining agent adopts polyacrylamide, stabilizer to select pollution-free adhesive, acidity regulator
Adjust the pH value of soil so as in neutral acidity on the weak side, disinfectant is used for killing except noxious bacteria contained in soil.
, by middle height, the low design implementation of periphery is smooth and rolls for solid waste of the present invention 1, and one is to reduce solid to give up
The space that gurry is occupied;Two is the extexine that solid waste is closed using embedding non-woven fabrics in clay or waterproof blanket, rainwater along
The inclined-plane that solid waste is constituted is oozed out to descending, effectively prevents rainwater from penetrating in solid waste, so as to prevent solid waste
Thing dissolves in rainwater and outside seepage diffusion because rainwater infiltration pollutes thing;Three is that fixative is added with solid waste,
Chemical pollutant and heavy metal element can be reduced by chemical reaction and attached function under conditions of no rainwater waters down
Activity;Four is to plant grass on the cultivation soil at the top of solid waste, plant trees, and has reached solid waste and has stacked field ecological recovery
Purpose.
Embodiment 2:
As shown in Figure 2, to avoid impervious barrier 3 from moving in solid waste 1, the present invention step (3) in, first after compaction
Solid waste 1 on stack thickness be 10 ㎝~20 ㎝ clay 2, compacting;Impervious barrier 3 is placed again, is stacked on impervious barrier 3 again
Thickness is the clay 2 of 10 ㎝~20 ㎝, compacting.
The present embodiment impervious barrier 3 adopts waterproof blanket, and the waterproof blanket is GCL, and it is natural by pass through that level matches somebody with somebody
Na-bentonite soil particle and corresponding additive are mixed into raw material, Jing needling processes and equipment, and bentonite clay particle is fixed on
Blanket waterproof roll made by between geotextiles and plastic woven cloth.GCL was both all special with earth working material
Property, and with excellent waterproof(Ooze)Performance.
So, impervious barrier 3 is difficult movement in solid waste 1, enhances the antiseepage effect of impervious barrier 3.
Remaining same embodiment 1.
