It foots the bill member 1 and closing unit 2.Landfill unit 1 is arranged in melt pit 3, and landfill unit 1 includes at least one landfill pond 11, landfill
Pond 11 has upper open and surrounds by landfill bottom of pond wall 111 and from the landfill pond side wall 112 that landfill bottom of pond wall 111 upwardly extends,
Wherein, landfill bottom of pond wall 111 includes armored concrete bottom wall 1111 and is covered on armored concrete bottom wall 1,111 first anti-
Infiltration layer 1112, landfill pond side wall 112 include armored concrete side wall 1121 and be covered on armored concrete side wall 1121 the
Two impervious barriers 1122.Closing unit 2, which is suitable for working as, fills up hazardous waste rear seal-cover in the upper opening in landfill pond 11 in landfill pond 11,
Closing unit 2 includes precast concrete facade panel 21 and the third impervious barrier being arranged on precast concrete facade panel 21.
Specifically, landfill pond 11 has upper open and upwardly extends by landfill bottom of pond wall 111 and from landfill bottom of pond wall 111
Landfill pond side wall 112 surround.Hazardous waste can pour into landfill pond 11 from the upper opening in landfill pond 11 as a result, by filling out
Pollution of the hazardous waste to underground water and soil can be obstructed by burying bottom of pond wall 111 and landfill pond side wall 112.Wherein, bottom of pond is filled
Wall 111 includes armored concrete bottom wall 1111 and the first impervious barrier 1112 being covered on armored concrete bottom wall 1111, landfill
Pond side wall 112 includes armored concrete side wall 1121 and the second impervious barrier 1122 being covered on armored concrete side wall 1121.
The landfill pond 11 for storing hazardous waste is formed using armored concrete bottom wall 1111 and armored concrete side wall 1121 as a result,
Main body rigid structure, neither easy-weathering aging, but be not likely to produce globality sliding；And by armored concrete bottom wall
1111 and armored concrete side wall 1121 on the first impervious barrier 1112 and the second impervious barrier 1122 is respectively set, can not only prevent
The filtrate of hazardous waste penetrates into outside landfill pond 11 and enters soil, avoids underground water and soil contaminated, and can be to avoid danger
The peculiar smell of dangerous waste is spread.
Closing unit 2 is suitable for closing when filling up hazardous waste rear seal-cover in landfill pond 11 in the upper opening in landfill pond 11
Unit 2 includes precast concrete facade panel 21 and the third impervious barrier being arranged on precast concrete facade panel 21.Pass through closing as a result,
Unit 2 is sealed in the upper opening in landfill pond 11, can be obstructed the hazardous waste in landfill pond 11 and be entered outside landfill Unit 11, pond
Environment.Using precast concrete facade panel 21, it is easy to take out when facilitating reprocessing after the hazard waste landfill several years；And pass through
Third impervious barrier is set on precast concrete facade panel 21, can not only prevent the filtrate of hazardous waste penetrate into landfill pond 11 it is outer and
It into soil, avoids underground water and soil contaminated, and can be spread to avoid the peculiar smell of hazardous waste.
The hazardous waste of embodiment rigidly fills system 100 according to a first aspect of the present invention, using armored concrete bottom wall
1111 and armored concrete side wall 1121 form the main body rigid structure in the landfill pond 11 for storing hazardous waste, use is prefabricated
Rigid body structure of the board concrete panel as closing unit 2, neither easy-weathering aging, and it is not likely to produce globality sliding,
And the environment that the hazardous waste in landfill pond 11 enters outside landfill unit 1 can be obstructed.By in armored concrete bottom wall
1111 and armored concrete side wall 1121 on the first impervious barrier 1112 and the second impervious barrier 1122 is respectively set, by prefabricated mixed
Third impervious barrier is set on solidifying soil panel 21, can not only prevent the filtrate infiltration landfill pond 11 of hazardous waste outer and enter soil
Earth avoids underground water and soil contaminated, and can spread to avoid the peculiar smell of hazardous waste.In addition, using precast concrete
Panel 21 is easy to take out when facilitating reprocessing after the hazard waste landfill several years.
Further include multiple bar shaped buttresses 4 as shown in Fig. 2, one embodiment according to a first aspect of the present invention, melt pit 3 by
Melt pit bottom wall 31 and the melt pit side wall 32 upwardly extended from melt pit bottom wall 31 formation, bar shaped buttress 4 is vertically arranged, bar shaped buttress 4
Lower end bury solid in melt pit bottom wall 31,4 upper end of bar shaped buttress supports landfill unit 1, landfill unit 1 and melt pit bottom wall 31 it
Between, between landfill unit 1 and melt pit side wall 32 keep space length (as shown in Figure 1 to Figure 3), to form visual detection area
14.As a result, by setting visual detection area 14, detection landfill unit 1 is facilitated to leak out with the presence or absence of percolate, such as can detecte
Whether 1 side wall of landfill unit or 1 bottom wall of landfill unit have percolate leakage out, prevent Hazardous Wastes Management soil and groundwater.
Further embodiment according to a first aspect of the present invention, melt pit bottom wall 31 are hardening bottom wall.Thus, it is possible to increase ground
The intensity for cheating 3 bottoms prevents landfill unit 1 from collapsing.
Some embodiments according to a first aspect of the present invention, the second impervious barrier 1122 are coated in armored concrete side wall
Dope layer on 1121 surface.Second impervious barrier 1122 of the dope layer as armored concrete side wall 1121 is used as a result, both
It can corrode, and can prevent the percolate of hazardous waste from leaking, and cost economy.
Further embodiment according to a first aspect of the present invention, dope layer are polyurethane coating layer.Polyurethane is used as a result,
Second impervious barrier 1122 of the dope layer as armored concrete side wall 1121, can not only corrode, but also can prevent hazardous waste
