Description
Technical field
The present invention relates to a kind of preparation method of agent for soil expansion and increment.Particularly a kind of waste resource (urban and rural buildings rubbish) that utilizes is the agent for soil expansion and increment of feedstock production and production method thereof, for comprehensive utilization town and country waste resource, turns waste into wealth and has opened up a new way.
Background technology
1. China's urban and rural buildings rubbish present situation
At present, along with the progress of society and the development of town and country construction thereof, the quantity of China's building waste has accounted for 30%～40% of municipal wastes total amount.Overwhelming majority building waste is without any processing, just transported to countryside or rural area by unit in charge of construction, adopt the mode of air storage or landfill to handle, consume funds such as a large amount of land acquisitions takes, refuse collection, simultaneously, clear with stacking process in drop with problems such as dust, sand-lime fly upward and caused the serious environmental pollution again.Along with China for protecting farmland and the promulgation and the enforcement of every laws and regulations of environment protection, how handling and discharge building waste has become the important topic that enterprise in charge of construction and environmental protection department face.
Building waste mostly is solid waste greatly, generally produces in process of construction or in the old building maintenance, demolishing process.Though the content of the various compositions of rubbish that building produced of different types of structure is different, but its essentially consist is consistent, and mainly waste material, various wrapping material and other waste etc. of the Steel Concrete pile crown that is cut down by soil, dregs, the mortar that is scattered and concrete, the masonry that picks the cutter generation and broken concrete, piling, metal, bamboo timber, decorations generation are formed.According to the pertinent data introduction, warp is to brick mix structure, and the rough Statistics of the construction material loss of buildings such as full cast-in-place structural and skeleton construction is at per ten thousand m
2In the construction process of building, only building waste residue will produce 500t～600t.If by this measuring and calculating, China's building waste residue that only construction produced and discharged every year just has 4,000 ten thousand tons, adds to remove in town and country to repair transformation, and building waste residue is hundreds of millions of.
Many wastes in the building waste are after letter sorting, rejecting or pulverize, can be used as renewable resource mostly utilizes again, as metals such as steel scrap muscle, scrap iron silk, waste electric wire and various steel scrap accessories, after sorting, concentrate, melting down again, can reprocess the steel that manufacture all size; Useless bamboo timber then can be used to make the imitation wood; Waste materials such as brick, stone, concrete can be used for masonry mortar, motar, beat concrete cushion etc. for sand after fragmentation, can also be used to make building material mades such as building block, Paving bricks, lattice brick.As seen, the comprehensive utilization building waste is to economize on resources, protect ecological effective way.In these areas, many advanced experiences of industrially developed country such as Japan, the U.S., Germany and treatment process very worth we use for reference.But it is few to utilize it to improve agricultural soil preserve moisture and fertility report.
2. Foreign Architecture rubbish fully utilizes present situation
Many wastes in the building waste can be used as renewable resource mostly and utilize again through after go-no-go, rejecting or pulverizing.The comprehensive utilization building waste is to economize on resources, protect ecological effective way.In this respect, the comparison that developed countries such as Japan, the U.S., Germany carry out early provides many advanced persons' experience and treatment process to us.Usually, material of construction, as the stone fragment of brick, its cost of material is more inexpensive than the material of recirculation.Because area is little, resource is deficient relatively, and the structure cost of material of Japan is higher than Europe.Therefore, the Japanese is considered as building waste in " building byproduct ", attaches great importance to it is developed again as renewable resources.Such as the port facility, and the Infrastructure accessory of other improvement projects can utilize the building stones of recirculation, the natural stone quarry gravel material of replacement a great deal of.
Japanese government had formulated " regeneration aggregate and regeneration concrete operating specification " in 1977, and set up in various places in succession to handle the regeneration source mill of concrete debris, produce recycled cement and regeneration aggregate, but the processing 100t/h of industrial scale maximum.Japanese government had formulated " resource is utilized promotion law again " again in 1991, and building wastes such as the dregs that produces in the regulation building construction process, concrete blocks, bituminous concrete piece, timber, metal must be sent to " renewable resources facility " and handle.Japan for the leading policy of building waste is: do not discharge building waste as far as possible from the working-yard; Building waste will utilize as much as possible again; Inconveniently then should suitably be handled for utilizing again.United States Government has then formulated " super fund method ", regulation: " any production has the enterprise of trade waste, must deal carefully with voluntarily, must not arbitrarily dump without authorization ".Thereby limited the generation of building waste on the source, the conscious made from construction refuse resource of seeking utilizes approach to impel each enterprise.Association of U.S. dwelling house contractor is promoting a kind of " conservation of resources room "; its wall is to build up with the tire and the aluminium alloy scrap that reclaim; the used most of steel material of roof truss is retrieved from the construction site; used sheet material is that sawdust and particles add that 20% polyethylene makes, and the main raw material of roofing is old newspaper and packing case carton.This dwelling house has not only actively utilized depleted metal, timber, cardboard, and the reasonable contradiction that has solved between acute housing shortage and the environment protection.In addition, the CYCLEAN company of the U.S. adopts microwave technology, recycling regeneration old asphalt pavement material that can 100%, its quality is with newly to mix asphalt road surface material identical, and cost can reduce by 1/3, has saved expenses such as refuse collection and processing simultaneously, has alleviated the The Surroundings in Cities pollution greatly; To passing through pretreated building waste, then transport " renewable resources processing enter " to, adopt burning method to focus on.
France CSTB company is Europe premier " refuse and construction industry " group, special " refuse and construction industry " business of planning as a whole in Europe.The waste management overall plan that company proposes has two general objectives: the one, by the environmental protection characteristic of new design building product is studied, from the output of control building site, source refuse; The 2nd, in construction, improve and pull down in the engineering, by assessment that the production of building site refuse and collection are made prediction, determining relevant recovery application program, thus the level of lifting waste management.The said firm uses Software tool that building waste is carried out controlling from producing to the whole process analysis of handling based on powerful database, makes a policy to aid in the different steps of buildings in useful life period.For example can assess the whole environmental protection of building products; Can be according to relevant implementation, maintenance classification, and different buildingss pulls down type, assess reducing the refuse amount that certain product produces; Can be to consultant personnel, main contractor, and contract mechanism (client) and provide relevant general view data with regard to a certain product or product line to environmental protection and healthy effect; Can make prediction to waste management required program and material; Can work out traffic program according to the end-use or the quality of refuse; The novel process of " reproducing " raw material with regard to any use is made in the feasibility aspect technology, the energy economy ﹠ environment and to be assessed, and can estimate the performance of product.In Holland, the annual refuse that produces of construction industry is approximately 14 * 10
6T, great majority are demolition and the product (stone, metal, the mixed and disorderly thing of plastics and timber) of transforming old building.At present, existing 70% waste material of buildings can be recycled utilization, but Dutch government wishes this per-cent is increased to 90%.Therefore, they have formulated a series of laws, set up the quality control system of dumping processing, forced recirculation operation of restriction refuse.The significant by-products of Holland's waste material of buildings cycling and reutilization is husky ash, output about 1 * 10
6Husky ash is contaminated easily, and it utilizes again is conditional.Holland has adopted husky grey recirculation network for this reason, is responsible for the effectively husky ash of sieve by letter sorting company: the pollution level classification according to it, store clean sand, and clear up contaminated sand.
Germany is divided into soil excavation, broken old material of construction, road excavation and building operation building site rubbish with building waste.The building of German federal Environment Fund meeting general headquarters is exactly to have used old concrete to gather materials.The destructive distillation combustion refuse treatment process of Siemens exploitation, can be with very clean the separating of various recyclable materials in the rubbish, be recycled, then be used for generating for the combustion gas that produces in the treating processes, the only remaining 3 kilograms/t of rubbish harmful heavy metal material after the destructive distillation burn processing has solved rubbish effectively and has taken large stretch of problem of ploughing.About utilizing urban and rural buildings rubbish to produce agent for soil expansion and increment, the multifunctional comprehensive of turning waste into wealth utilizes technology, and the author yet there are no report.
