Abstract
The utility model provides a salt pond landfill system of flexible safe landfill solid waste salt, includes former landfill barrier layer, landfill material layer, HDPE membrane and treats the solid-state waste salt of landfill, former landfill barrier layer is located the bottom, landfill material layer covers on former landfill barrier layer, digs the hole type with landfill material layer, HDPE covers on landfill material layer, solid-state waste salt is wrapped up by the HDPE membrane, treats salt pond landfill system landfill and fills the back, adopts the HDPE membrane to weld as an organic wholely on salt pond landfill system upper surface.
Description
Technical Field
The invention relates to the field of solid waste salt landfill methods, in particular to a salt pond landfill system for solid waste salt in a flexible safety landfill.
Background
The disposal of the solid waste salt is a problem which is puzzled for a long time in the industry at present, the main disposal mode is to directly fill the landfill site, the existing solid waste salt is directly filled in the landfill site, rainwater infiltration can dissolve the solid waste salt to form leachate containing high-salt wastewater, the high-salt wastewater is usually subjected to salt precipitation in an evaporation mode and then is buried, the disposal cost is high, the waste salt is infinitely circulated in landfill site-leachate-evaporation disposal, the disposal cost of enterprises is greatly improved, in addition, after the salt in the landfill pile is dissolved to form the leachate, the position of the salt will collapse to influence the safety and stability of the whole landfill pile.
Disclosure of Invention
In order to solve the problems, the invention provides the flexible and safe landfill solid waste salt pond landfill system which can effectively prevent the possibly generated problem that the leachate dissolves solid waste salt, reduce the subsequent leachate disposal cost of enterprises, and improve the stability and the safety of landfill piles.
The technical scheme of the invention is as follows: the utility model provides a salt pond landfill system of flexible safe landfill solid waste salt, includes former landfill barrier layer, landfill material layer, HDPE membrane and treats the solid-state waste salt of landfill, former landfill barrier layer is located the bottom, landfill material layer covers on former landfill barrier layer, digs the hole type with landfill material layer, HDPE covers on landfill material layer, solid-state waste salt is wrapped up by the HDPE membrane, treats salt pond landfill system landfill and fills the back, adopts the HDPE membrane to weld as an organic wholely on salt pond landfill system upper surface.
By adopting the technical scheme, as the solid waste salt is wrapped by the HDPE film, after the salt pond landfill system is filled, the HDPE film is welded on the upper surface of the salt pond landfill system into a whole, so that the problem that rainwater is contacted with the solid waste salt to generate leachate can be effectively prevented, the possibly generated leachate dissolves the solid waste salt can be effectively prevented, the subsequent leachate treatment cost of an enterprise is reduced, and the stability and the safety of a landfill yard stack body are improved; because the original landfill impervious layer is positioned at the bottom, the original landfill impervious layer is in a pit shape, the landfill material layer covers the original landfill impervious layer, and then solid waste salt is filled in the pit, so that the problem of stack body airtightness damage caused by tearing the salt pond can be prevented.
The invention further comprises the following steps: HDPE pipes are embedded in the landfill material layer, and the outer surface of each HDPE pipe is welded with the HDPE film into a whole.
Adopt above-mentioned technical scheme, because pre-buried HDPE pipe on the landfill material layer, produced rainwater can be temporarily discharged by this calandria during the landfill, because HDPE outside of tubes surface welds integratively with the HDPE membrane, adopts HDPE material welding shutoff this outlet when solid-state waste salt is buried soon.
The invention further comprises the following steps: the HDPE film is folded to a plurality of sizes to form an expansion joint.
Adopt above-mentioned technical scheme, because the solid-state waste salt in the salt pond landfill system can slightly displace, through turning over a plurality of sizes with the HDPE membrane, form the expansion joint, avoid tearing because of solid-state waste salt displacement causes solid-state waste salt.
Drawings
Fig. 1 is a schematic structural diagram of a salt pond landfill system for solid waste salt in a flexible safety landfill according to an embodiment of the invention.
Detailed Description
As shown in fig. 1, the salt pond landfill system for the solid waste salt of the flexible safe landfill comprises an original landfill impermeable layer 1, a landfill material layer 2, an HDPE (high-density polyethylene) membrane 3 and solid waste salt 4 to be buried, wherein the original landfill impermeable layer 1 is positioned at the bottom, the landfill material layer 2 covers the original landfill impermeable layer 1, the landfill material layer 2 is dug into a pit shape, the HDPE covers the landfill material layer 2, the solid waste salt 4 is wrapped by the HDPE membrane 3, and after the salt pond landfill system is filled, the upper surface of the salt pond landfill system is welded into a whole by the HDPE membrane 3; because the original landfill impervious layer 1 is positioned at the bottom, the original landfill impervious layer 1 is in a pit shape, the landfill material layer 2 covers the original landfill impervious layer 1, and then the solid waste salt 4 is filled in the pit, so that the problem of stack airtightness damage caused by tearing the salt pond can be prevented.
Because solid-state waste salt 4 is wrapped up by HDPE membrane 3, treat that salt pond landfill system landfill is solid back, adopt HDPE membrane 3 to weld as an organic whole on salt pond landfill system upper surface, can prevent effectively that rainwater and solid-state waste salt 4 from contacting and producing filtration liquid, can effectively prevent the problem that the infiltration liquid that probably produces dissolves solid-state waste salt 4, reduce the subsequent infiltration liquid of enterprise and deal with the cost, improve landfill yard stack stability and security.
Because pre-buried HDPE pipe 5 on landfill material layer 2, produced rainwater during the landfill can be discharged by this calandria temporarily, because 5 surfaces of HDPE pipe and 3 welding of HDPE membrane are integrative, adopt HDPE material welding shutoff this outlet when solid-state waste salt 4 is buried soon
The HDPE film 3 is folded to a plurality of sizes to form an expansion joint.
Because solid-state waste salt 4 in the salt pond landfill system can slightly shift, through turning over HDPE membrane 3 a plurality of sizes, form the expansion joint, avoid tearing because of solid-state waste salt 4 displacement causes solid-state waste salt 4.
