Abstract
The invention provides a soilless cover material for sanitary landfill of solid waste garbage. The soilless cover material for sanitary landfill of the solid waste garbage comprises components with parts by weight: water-soluble cellulose polymers 2-25 parts, plant fibers 20-100 parts, clay 10-100 parts, gypsum 5-50 parts and water 500-3000 parts, wherein the water-soluble cellulose polymers is an ionic type, and the plant fibers are an expanded type. The soilless cover material for sanitary landfill of the solid waste garbage is degradable, is about 5%-10% in water penetration rate, also has a certain amount of water permeability, and has great promotion effect for breeding of garbage natural degradation bacteria. The soilless cover material for sanitary landfill of the solid waste garbage eliminates garbage layering after being degraded, enables garbage of a whole landfill to be an entirety, and plays great role for improving garbage density. Compared with other cover methods, the soilless cover material for sanitary landfill of the solid waste garbage has great advantages in cost.
Description
technical field [0001] The invention relates to a covering material, in particular to a soilless covering material for sanitary landfill of solid waste. Background technique [0002] According to the requirements in my country's "Technical Specifications for Municipal Solid Waste Sanitary Landfill (CH17-2004)" and "Operation and Management Specifications for Domestic Waste Sanitary Landfill Sites (DB11 / T270-2005)", the design and operation process of sanitary landfill sites Among them, after the garbage enters the site, the spreading, compacting and covering of the garbage should be completed within 24 hours. [0003] There are two main forms of traditional garbage working face covering: soil covering and film covering. [0004] As we all know, the soil covering method is that after the solid waste is landfilled and compacted, many waste dumps are often covered with 20-30cm of compacted loess. This method has the characteristics of wasting storage capacity, high cost, and is...
