Description
Technical Field
The invention relates to a rainwater flow guide structure applied to environmental pollution treatment of a solid waste storage yard and a construction process, and belongs to the technical field of drainage systems of the solid waste storage yard.
Background
The solid waste, referred to as solid waste for short, is solid waste generated in the processes of industrial production, life and other activities, such as waste residues of coal gangue, fly ash, sulfur slag, steel slag, carbide slag, furnace slag and the like generated in production activities, sludge and garbage generated in life activities. Solid waste not only occupies a large amount of land resources, but also causes serious pollution to atmospheric environment, water environment, soil environment and vision. Fine particles and powder in the solid ash are blown by wind and are dried by the sun to generate raised dust, so that the surrounding atmospheric environment is polluted; harmful substances in the solid waste are piled up for a long time to generate spontaneous combustion and emit a large amount of harmful gas; various solid wastes are stockpiled in the open air, and harmful components permeate underground to pollute soil and underground water after being exposed to the sun and rain; some solid wastes themselves emit toxic gases and odors, deteriorating the environment; the black coal gangue and other solid wastes can bring visual pollution.
The most common method for solid waste disposal is land landfill, mountain landfill is usually adopted, according to the standard requirements, a stacking site is excavated, a clay layer, a bentonite blanket, a geomembrane, non-woven fabrics and sand gravel are laid, then solid waste is conveyed to the site for paving and rolling, harmless treatment is carried out, then top sealing is carried out at the top, pollutants are placed in a relatively closed environment, and pollution diffusion is prevented. In some historical solid waste storage yards, the base layer is not provided with an impermeable layer, and only a surface covering method is adopted for treatment in order to prevent direct exposure of solid waste and rainwater from permeating into the pile body, namely, after the solid waste is paved, leveled and rolled, a layer of geomembrane is covered on the surface of the solid waste to be matched with concrete for covering. Because the mountain bodies on the two sides of the valley are extremely irregular in shape, the junction between the mountain bodies and solid wastes is not easy to compact, and the gap is large, not only can rainwater on the mountain bodies or even the upper parts of the mountain bodies be directly poured into a solid waste storage yard to influence the safety and stability of the storage yard, but also a large amount of percolate is generated to pollute soil, underground water and surface water at the downstream, and the rainwater can also serve as a wind leakage channel of a waste rock storage yard and a sulphur slag storage yard, so that the natural fire of the storage yard can be easily caused, and the technical problem of the management of.
