Abstract
The invention discloses a degradable soil-free environment-friendly material for covering landfill. The soil-free material is prepared by mixing component A and component B with water, wherein the component A is a combination of a film-forming agent and a surfactant, the component B is a fiber substance. When the soil-free material is for use, the components are mixed according to a ratio for forming of pasty matter which is sprayed on the surface of garbage wastes by a spraying machine, and a protective film with a thickness of 0.01-0.03 m on the surface of the garbage wastes is formed during rapid drying solidification. The soil-free material is capable of effectively controlling the problems of landfill odor, flying garbage, birds, dust, rainwater erosion and vegetation growth.
Description
Technical field
The present invention relates to a kind of cladding material, particularly relate to a kind of cover refuse landfill rubbish without soil material.
Background technology
In economy, grow continuously and fast, when living standard improves rapidly, urbanization process constantly accelerates, the output of China's domestic waste also grows with each passing day.In rubbish, the contained harmful components with producing, can pollute atmosphere, soil, water body, not only have a strong impact on city environmental quality, and directly threaten health, become one of social effects of pollution.Therefore, domestic waste is treated as great environmental problem urgently to be resolved hurrily.At present, China produces per year more than rubbish reached 450kg per capita, and municipal refuse annual production surpasses 100,000,000 tons, and annual growth is that 8% ~ 10%，Yi Yu developed country is close.Modern sanitary dumping engineering is the main method of processing municipal refuse all over the world.According to the requirement in China " urban domestic refuse sanitation burying landfill technical specification (CH17-2004) " and " Sanitary Landfill operational management standard (DB11/T270-2005) ", in the design and running process of sanitary filling field, rubbish should complete the paving of rubbish, compacting, covering work in 24h after marching into the arena.In the soot of China's overwhelming majority, also use the compacting clay of 0.2-0.25m to cover, using compacting clay to carry out landfill yard while covering, existing storage capacity, expensive, the problems such as collection that are unfavorable for garbage degradation and ooze drop liquid of taking.The research of new cladding material and application, will promote garbage sanitary filling field the applying of China, and is conducive to promote the urban garbage disposal of China, aspect reducing garbage disposal cost, improving treatment effect, is important breach especially.
Summary of the invention
The object of the invention is to overcome existing natural clay as the shortcoming that covers refuse landfill material, a kind of cladding material of instead of clay be provided, be a kind of brand-new environment-friendly type degradable without native cladding material.
Realize main technical schemes of the present invention:
Described cladding material is mixed and forms with water by component A and B component, and component A is the composition of film forming agent and surfactant, and B component is fiber substance, wherein film forming agent is 5-20 parts, 0.5-1 part, surfactant, 15-30 parts of fiber substances, 20-80 parts, water.
Described film forming agent is the high molecular polymer that butyl acrylate, styrene, methyl methacrylate, Methacrylamide, acrylamide form by emulsion polymerization.Butyl acrylate belongs to soft monomer, can carry out copolymerization with various hard monomer methyl methacrylates, styrene, acrylamide, Methacrylamide, crosslinked, grafting becomes many kinds of acrylic resin products of 200-700, is widely used as adhesive.
Described film forming agent is selected from one or more in polyvinyl alcohol, starch, polyacrylamide, carboxymethyl cellulose, redispersible latex powder.The easy film forming of polyvinyl alcohol, the mechanical performance of its film is good, and the hot strength of film raises and strengthens with the degree of polymerization, alcoholysis degree.Polyvinyl alcohol and hydrophilic fiber have good bonding force, ordinary circumstance, and the degree of polymerization, alcoholysis degree are higher, and adhesive strength is stronger.Polyacrylamide can make suspended material by charge neutrality, and bridge formation suction-operated plays flocculation, can play adhesive effect by effect machinery, physics, chemistry, under neutral and acid condition, all has thickening power.Carboxymethyl cellulose can form full-bodied colloid, has adhesion, thickening, flows, emulsion dispersion, figuration, water conservation, protecting colloid, film forming, acidproof, salt tolerant, is suspended characteristic.Redispersible latex powder is the copolymer of ethene, vinylacetate, usings polyvinyl alcohol as protecting colloid, has extremely outstanding water resistance and adhesion strength.
Described surfactant is selected from one or more in lauryl sodium sulfate, neopelex, polyoxyethylene 20 sorbitan monolaurate.Polyoxyethylene 20 sorbitan monolaurate is a kind of non-ionic surface active agent, is the large molecule of a class, and existing hydrophilic part on molecule has again the part of oleophylic, has emulsification, diffusion, solubilising, stable effect.
Described fiber substance is paper fiber or string.
Described paper fiber is selected from one or more paper scrap of old and useless newspaper, package paper, carton, cultural paper; Described string is selected from one or more of wood fibre, agricultural crop straw, vegetable stem stem.
Material of the present invention adopts conventional method preparation, mix Hou Jiashui and stir into pulpous state, by spray seeder, spray the garbage waste material surface of required covering, after dry solidification, take cover layer off, use the tectal thickness of vernier caliper measurement, material of the present invention forms the thick covering rete of one deck 0.01-0.03m on garbage waste material surface.
Cladding material of the present invention under the effect of acid, alkali, heat, light, microorganism and oxygen, the degraded of can rupturing, thus reduce the pollution to environment.
The beneficial effect of material of the present invention: the film forming on garbage waste material surface after dry solidification, can intercept foul odour and affect surrounding environment, can also effectively stop rainwater to flow to regulating reservoir and cause the dirty mixing of rain, thereby minimizing sewage load, save cost of sewage disposal, and can flyproof and bird, dust protection, antiseep, anti-flying upward, reduces storage capacity.
Material of the present invention, by control group distribution ratio, can meet the requirement of garbage loading embeading cover time.
