[0003] As a specialized hazardous waste disposal engineering facility, landfill stores and isolates hazardous waste to minimize its impact on human health and the ecological environment. However, after a long period of storage of waste salt, it is For most of the current flexible landfills, there is a great possibility of leakage, a great risk, and a great safety hazard to the regional environment.
If a safety accident occurs, the consequences will be disastrous

Embodiment
[0032] This embodiment provides a kind of insoluble waste salt treatment method, and this method is applied to such as figure 1 In the shown landfill, the landfill includes more than three landfill pits, and the bottom of the landfill pit is provided with an anti-seepage layer 5. Preferably, the anti-seepage layer 5 is followed by foundation soil layer, flexible anti-seepage layer from bottom to top. Permeable film layer, clay anti-seepage layer and flexible anti-seepage film layer, preferably, the flexible anti-seepage film used in the flexible anti-seepage film layer is a high-density polyethylene geomembrane, which can prevent waste salt from penetrating into the soil and causing pollution to the soil ; Each landfill pit is provided with more than three layers of landfill layers in the vertical direction; a seepage isolation storage layer 4 formed by concrete pouring is provided between the anti-seepage layer 5 and the landfill layer above it, and the seepage isolation stora...

The invention discloses a treatment method for insoluble waste salt, which relates to the technical field of hazardous waste treatment. The method comprises: digging out a landfill pit, laying a foundation in the landfill pit, laying an anti-seepage layer on the foundation; laying an anti-seepage layer on the anti-seepage layer Concrete pouring is used to lay the seepage isolation storage layer, which is inclined to one side during laying, and a liquid accumulation tank is set at the lower part of the lower side; on the seepage isolation storage layer, concrete is poured at equal intervals to set up inverted trapezoidal spacers, Form a sealed landfill area; fill the treated insoluble waste salt into the sealed landfill area; after all the sealed landfill areas in the same landfill layer are filled, lay a sealing layer on the insoluble waste salt; Inverted trapezoidal columns are set on the layer to form a sealed landfill area; the treated insoluble waste salt is filled into the sealed landfill area; after all the sealed landfill areas in the same landfill layer are filled, the insoluble waste salt Lay sealer over salt; repeat landfill until complete. The present invention has the advantage of high safety.
Description
technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a treatment method for insoluble waste salt. Background technique [0002] Large and medium-sized chemical enterprises such as electroplating, pharmaceuticals, pesticides, daily chemicals, and sewage treatment will produce a large amount of waste salt and other semi-solid or solid hazardous waste in the chemical production process, which has a greater impact on the environment; while some existing waste salt The harmless disposal method is landfill. [0003] As a specialized hazardous waste disposal engineering facility, landfill stores and isolates hazardous waste to minimize its impact on human health and the ecological environment. However, after a long period of storage of waste salt, it is For most of the current flexible landfills, there is a great possibility of leakage, a great risk, and a great safety hazard to the regional environment. If a safety ac...
