A hazardous waste rigid landfill system 100 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 5; a hazardous waste shipping system 200 according to an embodiment of the second aspect of the present invention is described with reference to fig. 6.
As shown in fig. 1-5, a hazardous waste rigid landfill system 100 according to an embodiment of the first aspect of the present invention includes a landfill unit 1 and a field unit 2. The landfill unit 1 is disposed in the pit 3, the landfill unit 1 including at least one landfill pool 11, the landfill pool 11 having an upper opening and being surrounded by a landfill Chi Debi and a landfill pool side wall 112 extending upward from the landfill pool bottom wall 111, wherein the landfill pool bottom wall 111 includes a reinforced concrete bottom wall 1111 and a first barrier layer 1112 covering the reinforced concrete bottom wall 1111, and the landfill pool side wall 112 includes a reinforced concrete side wall 1121 and a second barrier layer 1122 covering the reinforced concrete side wall 1121. The enclosure unit 2 is adapted to be covered on an upper opening of the landfill pool 11 after the landfill pool 11 is filled with hazardous waste, and the enclosure unit 2 includes a precast concrete panel 21 and a third barrier layer provided on the precast concrete panel 21.
Specifically, the landfill pool 11 has an upper opening and is surrounded by a landfill Chi Debi 111 and a landfill pool side wall 112 extending upward from the landfill pool bottom wall 111. Thus, the hazardous waste can be poured into the landfill tank 11 from the upper opening of the landfill tank 11, and the pollution of the underground water and the soil by the hazardous waste can be blocked by the landfill Chi Debi 111 and the landfill tank side wall 112. Wherein the landfill bottom wall 111 comprises a reinforced concrete bottom wall 1111 and a first barrier layer 1112 overlaying the reinforced concrete bottom wall 1111, and the landfill side wall 112 comprises a reinforced concrete side wall 1121 and a second barrier layer 1122 overlaying the reinforced concrete side wall 1121. Thus, the adoption of the reinforced concrete bottom wall 1111 and the reinforced concrete side walls 1121 forms a main rigid structure of the landfill pool 11 for storing dangerous wastes, which is not easy to weathere and age, but not easy to generate integral sliding; and by providing the first barrier layer 1112 and the second barrier layer 1122 on the reinforced concrete bottom wall 1111 and the reinforced concrete side wall 1121, respectively, not only can the filtrate of dangerous waste be prevented from penetrating out of the landfill pool 11 to enter the soil, the groundwater and the soil can be prevented from being polluted, but also the odor diffusion of dangerous waste can be prevented.
The enclosure unit 2 is adapted to be covered on an upper opening of the landfill pool 11 after the landfill pool 11 is filled with hazardous waste, and the enclosure unit 2 includes a precast concrete panel 21 and a third barrier layer provided on the precast concrete panel 21. Thus, by closing the enclosure unit 2 over the upper opening of the landfill pool 11, hazardous waste in the landfill pool 11 can be blocked from entering the environment outside the landfill pool 11 unit. The precast concrete panels 21 are adopted, so that hazardous wastes are convenient to be taken out easily after being buried for a plurality of years and then treated; and by providing the third impermeable layer on the precast concrete deck 21, not only can the filtrate of the hazardous waste be prevented from penetrating out of the landfill pool 11 to enter the soil, the groundwater and the soil can be prevented from being polluted, but also the odor diffusion of the hazardous waste can be prevented.
According to the hazardous waste rigid landfill system 100 of the first aspect of the embodiment of the present invention, the reinforced concrete bottom wall 1111 and the reinforced concrete side walls 1121 are used to form the main rigid structure of the landfill pool 11 for storing the hazardous waste, and the precast slab concrete panels are used as the rigid main structure of the enclosure unit 2, so that the hazardous waste in the landfill pool 11 is not easily weathered and aged, is not easily integrally slid, and can be blocked from entering the environment outside the landfill unit 1. By providing the first barrier layer 1112 and the second barrier layer 1122 on the reinforced concrete bottom wall 1111 and the reinforced concrete side wall 1121, respectively, by providing the third barrier layer on the precast concrete deck 21, not only can the filtrate of hazardous waste be prevented from penetrating out of the landfill pool 11 to enter the soil, groundwater and soil are prevented from being polluted, but also the odor diffusion of hazardous waste can be avoided. In addition, the precast concrete deck 21 is convenient for the hazardous waste to be easily taken out when being disposed after being buried for several years.
As shown in fig. 2, according to an embodiment of the first aspect of the present invention, the pit 3 is formed of a pit bottom wall 31 and pit side walls 32 extending upward from the pit bottom wall 31, the pit 4 is vertically disposed, the lower ends of the pit 4 are buried in the pit bottom wall 31, the upper ends of the pit 4 support the landfill unit 1, and a space distance (as shown in fig. 1 to 3) is maintained between the landfill unit 1 and the pit bottom wall 31, and between the landfill unit 1 and the pit side walls 32, to form the visual inspection area 14. Thus, by providing the visual detection area 14, it is convenient to detect whether or not there is leakage of the percolate in the landfill unit 1, for example, whether or not there is leakage of the percolate in the side wall of the landfill unit 1 or the bottom wall of the landfill unit 1 can be detected, and the pollution of the soil and the groundwater by the hazardous waste can be prevented.
According to a further embodiment of the first aspect of the invention, the pit bottom wall 31 is a hardened bottom wall. Thereby, the strength of the bottom of the pit 3 can be increased, preventing the collapse of the landfill unit 1.
According to some embodiments of the first aspect of the invention, the second barrier layer 1122 is a paint layer applied to the surface of the reinforced concrete sidewall 1121. Thus, the use of a paint layer as the second barrier 1122 of the reinforced concrete sidewall 1121 can both corrode and prevent leakage of hazardous waste leachate and is cost effective.
According to a further embodiment of the first aspect of the invention, the coating layer is a polyurethane coating layer. Thus, the polyurethane coating layer is used as the second barrier layer 1122 of the reinforced concrete sidewall 1121, which can not only corrode but also prevent leakage of leachate from hazardous waste, and is cost effective.
According to some embodiments of the first aspect of the invention, the first barrier layer 1112 is a geomembrane. Thus, the first barrier layer 1112 is a geotechnical layer that is both corrosive and resistant to leakage of hazardous waste leachate and is cost effective.
According to a further embodiment of the first aspect of the present invention, the geomembrane is a high-density polyethylene HDPE geomembrane, and the anti-corrosion and anti-seepage effects are better. For example, a 2.0mm thick smooth infiltration locating high density polyethylene HDPE geomembrane is used to cover the surface of the reinforced concrete bottom wall 1111 of the landfill 11 to better prevent leakage of leachate.
According to a further embodiment of the first aspect of the present invention, the geomembrane is overlaid on the surface of the reinforced concrete bottom wall 1111 with the edges of the geomembrane folded up and conforming to the landfill side wall 112 adjacent to the landfill bottom wall 111. Thus, by folding the sides of the geomembrane upward and against the landfill side walls 112, leakage of the leachate from the junction of the landfill side walls 112 and the landfill bottom wall 111 can be prevented.
According to a still further embodiment of the first aspect of the invention, the edge fold height of the geomembrane is not less than 0.4m. This better prevents leakage of leachate from the junction of the landfill side wall 112 and the landfill bottom wall 111.
According to a further embodiment of the first aspect of the present invention, the upper surface of the first barrier layer 1112 is further provided with a first slope finding layer 1113. By arranging the first slope finding layer 1113, the percolate of the hazardous waste can flow to the lowest position of the first slope finding layer 1113; the first barrier layer 1112 can also be protected from being crushed by the poured hazardous waste, and the first barrier layer 1112 can be prevented from being polluted by the hazardous waste to become hazardous waste, thereby preventing the hazardous waste treatment amount from being increased.
