Abstract

The invention discloses a bentonite-based treatment agent for a refuse landfill and a preparation method thereof, and relates to the technical field of environmental protection. The bentonite-based treatment agent is prepared in the mode that bentonite raw ore, a sodium agent, an organification reagent and water are mixed and stirred uniformly. The bentonite-based treatment agent is prepared fromthe following components in parts by weight: 100 parts of the bentonite raw ore, 0.5-8 parts of the sodium agent, 0.1-10 parts of the organification reagent and 5-20 parts of the water through the specific preparation method. According to the bentonite-based treatment agent for the refuse landfill and the preparation method thereof, the bentonite raw ore is modified, the modified bentonite-based treatment agent has the capability to adsorb inorganic heavy metal and organic pollutants, thus poisonous and harmful substances in refuse are adsorbed, and soil and water body pollution is prevented;in addition, the treatment effect of the refuse treatment agent can be enriched by adding shell activated carbon; and the procedures of the preparation method are simple, and raw materials are easy toobtain.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a bentonite-based treatment agent for landfills and a preparation method thereof. Background technique [0002] The existing garbage landfill is a place where garbage is piled up under the sanitary landfill method. The garbage sanitary landfill is widely used in China because of its low cost and good sanitation. The garbage landfill is generally filled with layered soil Garbage is processed by means of piled up a layer of garbage and then covered with a layer of loess, so that it is easy to reduce the pollution of garbage. [0003] Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 crystal structure composed of two silicon-oxygen tetrahedra sandwiching a layer of aluminum-oxygen octahedron. Due to the formation of montmorillonite unit cells There are some cations in the layered structure...
