Soilless rubbish capping material and application thereof

Abstract

The invention discloses a soilless rubbish capping material and an application thereof. The soilless rubbish capping material comprises the following components in parts by weight: 0.1-50 parts of cement, 0.1-10 parts of fibre and 0.1-50 parts of macromolecule binding agent. The application thereof comprises the following steps: mixing the soilless rubbish capping material and water in proportion of 1:0.26-0.032 and stirring uniformly, and evenly spraying the mixed slurry on a rubbish site to form a closed capping surface. The invention has the advantages that: an environmental macromolecule composite is used for replacing covering soil to solve the problem of soil shortage; operation time and labour for covering soil are reduced; total capacity of the rubbish site is increased by about 30% with obvious economic benefit; dust pollution to atmosphere occurred in the landfill process in the rubbish site is obviously restrained; pathogenic bacteria infection caused by foraging birds is effectively controlled; growth and breeding of pathogenic bacteria are effectively controlled; and an anti-flaming material is used for effectively preventing rubbish sites from explosions and fires.

Description

technical field [0001] The invention belongs to the field of daily life, and in particular relates to a covering material in the treatment process of domestic garbage, and also relates to the application of this material in garbage treatment. Background technique [0002] With the acceleration of my country's urbanization process and the advancement of urban-rural integration, the garbage generated by urban life is also increasing. Disposing of household garbage has become an important task for building a harmonious society. For a long time, landfill has been the main way of domestic waste disposal in my country. As of 2005, landfill disposal of municipal solid waste accounted for about 86% of the total. Taking Shanxi Province as an example, during the "Eleventh Five-Year Plan" period, Shanxi Province will invest 3.3 billion yuan to build 100 domestic waste landfills. The total construction scale of new projects can handle 17,469 tons of domestic waste per day. Landfills ...

Problems solved by technology

Although some landfills are currently trying to use cover film (a plastic film) to replace the soil layer, it has not been fully promoted due to problems such as cost, construction difficulty, and inability to flame retardancy.
