Abstract
The invention discloses a kind of degradable without native environment-friendly materials for covering refuse landfill, it to be mixed with water by component A and B component and forms, component A is the composition of film forming agent and surfactant, B component is fiber substance, a kind of material of thick pulp is stirred into after preparing in proportion during use, product spray seeder is sprayed on garbage waste material surface, in dry solidification process rapidly, the thick diaphragm of 0.01-0.03m can be formed on garbage waste material surface, effectively can control the smell of refuse landfill, rubbish flies upward, bird, dust, rain erosion and vegetation growth problem.
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 sustain economic rapid growth, while living standard improves rapidly, urbanization process constantly accelerates, the output of China's domestic waste also grows with each passing day.Contained with the harmful components produced in rubbish, can pollute air, 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 be treated as great environmental problem urgently to be resolved hurrily.At present, China produces rubbish per capita per year and reaches more than 450kg, and municipal refuse annual production is more than 100,000,000 tons, and annual growth is 8% ~ 10%, is close with developed country.Modern sanitary dumping engineering is the main method 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 specification (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.Also use the clay compaction of 0.2-0.25m to cover in the soot of China's overwhelming majority, using clay compaction to carry out landfill yard when covering, there is problems such as taking storage capacity, expensive, the collection that is unfavorable for garbage degradation and Leachate site.New cladding material research and apply, will promote garbage sanitary filling field applying in China, is conducive to the urban garbage disposal promoting China, especially in reduction garbage disposal cost, raising treatment effect, is important breach.
Summary of the invention
The object of the invention is to overcome the shortcoming that existing natural clay is used as to cover refuse landfill material, a kind of cladding material of alternative 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 to be mixed with water by component A and B component and forms, and component A is the composition of film forming agent and surfactant, and B component is fiber substance, wherein film forming agent 5-20 parts, 0.5-1 part, surfactant, fiber substance 15-30 parts, 20-80 parts, water.
The high molecular polymer that described film forming agent is butyl acrylate, styrene, methyl methacrylate, Methacrylamide, acrylamide are formed by emulsion polymerization.Butyl acrylate belongs to soft monomer, can carry out copolymerization, crosslinked, grafting becomes 200-700 many kinds of acrylic resin products, be widely used as adhesive with various hard monomer methyl methacrylate, styrene, acrylamide, Methacrylamide.
Described film forming agent be selected from polyvinyl alcohol, starch, polyacrylamide, carboxymethyl cellulose, redispersible latex powder one or more.The easy film forming of polyvinyl alcohol, the good mechanical performance of its film, the hot strength of film raises with the degree of polymerization, alcoholysis degree and strengthens.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, bridge formation suction-operated, plays flocculation, by machinery, physics, the effect of chemistry, play adhesive effect, under neutral and acid condition, all have thickening power.Carboxymethyl cellulose can form full-bodied colloid, has adhesion, thickening, flowing, emulsion dispersion, figuration, water conservation, protecting colloid, film forming, acidproof, salt tolerant, is suspended characteristic.Redispersible latex powder is the copolymer of ethene, vinylacetate, using polyvinyl alcohol as protecting colloid, has extremely outstanding water resistance and adhesion strength.
Described surfactant be selected from lauryl sodium sulfate, neopelex, polyoxyethylene 20 sorbitan monolaurate one or more.Polyoxyethylene 20 sorbitan monolaurate is a kind of non-ionic surface active agent, and be the large molecule of a class, on molecule, existing hydrophilic part, 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 the paper scrap of one or more of old and useless newspaper, package paper, carton, cultural paper; Described string be selected from wood fibre, agricultural crop straw, vegetable stem stem one or more.
Material of the present invention adopts conventional method preparation, add water after mixing and stir into pulpous state, the garbage waste material surface of required covering is sprayed by spray seeder, after dry solidification, take cover layer off, use the tectal thickness of vernier caliper measurement, material of the present invention forms the thick cover layer 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, degraded of can rupturing, thus reduce the pollution to environment.
The beneficial effect of material of the present invention: at the film that garbage waste material surface is formed after dry solidification, foul odour can be intercepted and affect surrounding environment, rainwater effectively can also be stoped to flow to regulating reservoir and to cause rain dirt mixing, thus minimizing sewage load, save cost of sewage disposal, and can flyproof and bird, dust protection, antiseep, anti-ly to fly upward, reduce storage capacity.
Material of the present invention, by control group distribution ratio, can meet the requirement of garbage loading embeading cover time.
Specific embodiment
Embodiment one,
Embodiment two,
Cladding material prepared by embodiment one and embodiment two, uses spray seeder with 2 ~ 3kg/m
2quantity for spray spray on solid refuse surface, the duration reaches 6 ~ 8 months, can resist strong wind and rainwater and soak, have good bank protection effect to the export-oriented slope of rubbish heap.
Embodiment three,
Embodiment four,
Cladding material prepared by embodiment three and embodiment four, uses spray seeder with 1.5 ~ 2kg/m
2quantity for spray spray on solid refuse surface, sustainable 1 ~ 2 month of effective time, strong wind and rainwater can be resisted and soak, have good bank protection effect to the export-oriented slope of rubbish heap.
Embodiment five,
Cladding material prepared by embodiment five, uses spray seeder with 1.5 ~ 2kg/m
2quantity for spray spray on solid refuse surface, sustainable 10 ~ 20 days of effective time, strong wind and rainwater in short-term can be resisted and soak, the effective dust controlling harmful waste building site, flying upward of round-the-clock control light refuse.
