Embodiment Construction

[0029] The present invention will be further elaborated and explained below in conjunction with the accompanying drawings and specific examples. The various techniques in the present invention can be combined without mutual conflicts.

[0030] Referring to the drawings. The retired hazardous waste rigid landfill system provided by the present invention includes a hazardous waste landing reservoir region 1, a discharge passage 2, an overhaul interlayer 3, a door crane 4, a steel structure, and a person operation walkway 6.

[0031] The hazardous waste landfill area 1 is made over the maintenance interlayer 3, which is composed of several landfill units 10, and the hazardous waste landing reservoir zone 1 is divided into regional division according to the characteristics of hazardous waste. Each area contains one or more landfill units, and the landfill unit is preferably set in a matrix, not only facilitates the construction building, but also facilitates management and door cranes...

Abstract

The invention provides a retrievable hazardous waste rigid landfill system and an operation method. The retrievable hazardous waste rigid landfill system comprises a hazardous waste landfill reservoir area, a discharging channel, an overhauling interlayer, a portal crane, a steel-structured canopy and a personnel operation walkway plate. The hazardous waste landfill reservoir area is erected on the overhauling interlayer and composed of a plurality of landfill units. Each landfill unit comprises a reinforced concrete retaining wall and a bottom plate and is provided with a bottom plate anti-seepage system, a retaining wall anti-seepage system and a leachate collecting pipe, wherein pipe walking lines of the leachate collecting pipes are mainly located in the overhauling interlayer. The overhauling interlayer is an overhead layer and located below the hazardous waste landfill reservoir area. The portal crane is located above the landfill reservoir area. The steel-structured canopy is located on the upper portion of a crane. Personnel walkways are arranged on the periphery or / and in the landfill reservoir area. The retrievable hazardous waste rigid landfill system has more reliable safety, operable retrievable landfill is achieved, and management and maintenance are facilitated.

Description

Technical field [0001] The present invention belongs to the field of hazardous waste safety landfill, which specifically involves a retired hazardous waste rigid landfill system and operation method. Background technique [0002] "Hazardous Waste Dilling Pollution Control Standard" (GB18598-2019) (GB18598-2019) (hereinafter referred to as "Standard") is formally proposed in the form of a hazardous waste rigid landfill. Standard from the functional angle of the reinforced concrete design, waterproof level, anti-seepage anti-corrosion material, rain and visual leakage function of rigid landfill, and visual leakage function. However, the standard does not have a detailed description of the design and landfill operation flow for the specific functional module of hazardous waste rigid landfill. [0003] At present, the completed hazardous waste rigid landfill is mainly referred to in the "Technical Requirements for Hazardous Waste Safety Flying Project Construction" (Han Dynasty [2004...
