Description

Garbage concrete and technology thereof
The present invention relates to environmental protection and new building material technical field, specifically utilize rubbish to produce garbage concrete and production technique thereof.
Existing waste disposal method mainly contains landfill, burning and stacking three major types.
Advanced country abroad is the method for the processing municipal wastes of the best to build garbage incinerating power plant.Treatment of urban garbage has developed into new high-tech industry in some developed country, has both helped environment protection, has saved a large amount of starting material and the energy again.In these countries,, just accomplished the rubbish packing, transported that classification is handled by class from this cell of family.The rubbish that can burn is used for burning electricity generation.
But burning electricity generation several aspects below are difficult to tally with the national condition:
1, in China, real life level and civilization degree temporarily do not reach the domestic refuse Complete Classification of each family and handle.
2, burning electricity generation only is the part of municipal wastes, and on the one hand the required rubbish of burning electricity generation must reach certain fuel value, and the municipal wastes that a large amount of low molecule inorganicss constitutes can't be used for burning electricity generation, for example building waste etc.; On the other hand, the resistates of burning electricity generation still needs landfill.
3, burning electricity generation still produce to pollute atmosphere, the plastics in the municipal wastes (particularly chloride etc. objectionable impurities), and the gas during burning has serious destruction to atmospheric ozone layer.
4, build burning electricity generation factory and need huge investment.We compare the landfill of existing treating refuse, the method for burning with " garbage concrete ", just obviously find out their investment and the difference of economic results in society from following table:
Refuse treatment investment and benefit are relatively
Garbage concrete Landfill Burn
Day output (ton) 6000 (annual 1800000 tons)
Floor space (mu) 60 ?4000 200
Gross investment (ten thousand yuan/year) 5000 ?5000 3,300,000,000 yuan of disposable inputs
Annual value of production (hundred million yuan) 6 Do not have Founding the factory does not have the output value in two years
Economic benefit (profit) (ten thousand yuan) 6000,20 years totally 12 hundred million yuan There are not 1,000,000,000 yuan of national total expenditures in 20 years In average 1.6 hundred million first year, recouped capital outlay in 20 years
Landfill and stacking: the traditional method of Shi Yonging for a long time, the method that still generally use in present most of city, this method is to waste, environment damage, the burden of country and the hazardness that people are lived of resource (resources such as soil and rubbish), being obvious to all, also is disgustful.
Except landfill and burning method, also have some new methods both at home and abroad to refuse treatment.As Japanese railway synthetic study institute research and utilization depleted non-combustible waste as the rail quieter material; First the organic waste treatment unit in Shanghai can become harmless favourable organic feed by additive with organic waste, also leftovers can be become feed through microbial fermentation; Utilize plastic waste oiling technology in addition, prepare to open up " second oil field " or the like.These all are to refuse treatment and good thinking of utilizing once more and test direction, but these also all are faced with the practical difficulty of " rubbish needs go-no-go, classification to handle ", and can only be that wherein sub-fraction is utilized.
The big city of the world today all faces the serious threat of " garbage-surrounded city ".Rubbish, " refuse " that this can't suppress to increase become the major issue that has influence on national economy.If can not deal carefully with these municipal wastess, must overflow.Have data to show, whole nation rubbish storage over the years has been occupied more than 500,000,000 square metre of soil up to more than 60 hundred million tons, and wherein the domestic waste 90 percent or more does not obtain handling, a pile it, have more than 200 city to be absorbed among the rubbish encirclement.It is reported that Beijing has 450 diameters at the scrap heap more than 50 meters, the arable land that the suburb is accounted for by rubbish has surpassed 10000 mu, and the place in 30 kilometers of Beijing outside the citys has been difficult to find the place of heap garbage again; In Shanghai, the scrap heap that surpasses 20 square metres has 2000 places; In Guangzhou, suburb rubbish takes up an area of 69 hectares; Even in many small cities, the view of rubbish horizontal stroke " corpse " wilderness, filthy four streams also is seen everywhere.Along with society and expanding economy, environmental pollutions such as sewage, waste gas, hot-tempered sound, tropical island effect are arrived in the suburb with people's body in city and are lived, if piled with rubbish on the soil in suburb, where will people base oneself upon again so? and, rubbish can distribute stench, grows mosquitos and flies, polluted source, spread disease, how could people live and work in peace and contentment again so?
" earth has only one ", in today that the global environmental protection consciousness of protecting grows to even greater heights, radical cure " garbage-surrounded city " has become people's common voice.In recent years, the National People's Congress of big and medium-sized cities such as China Guangzhou, Nanjing, Beijing all has this to be appealed or proposal, urges government to accelerate to solve the municipal wastes problem.At present, the collection of China's domestic waste, clear, handle basically and bear by government.Mentionlet alone the city of financial strain makes garbage as resource,, also be unattainable exactly will reach innoxious purpose.The treatment process of simple stacking or simple and easy burning is adopted in the present refuse treatment of China mostly, and the way of this " founding a room in the strange land " is not only wasted a large amount of energy and money every year, and the resources loss that causes reaches hundred million yuan of 250-300.It is reported that Beijing produces 13000 tons of rubbish every day, only have an appointment 31% by sanitary landfill, 2% compost treatment, 0.8% burns, and all the other are most of to be air storage.In Shanghai, only the social life rubbish that average every day produces of urban district is with regard to 8000 tons more than (peak day, quantity of refuse was up to 13000 tons), and the output of annual rubbish is up to more than 300 ten thousand tons, and increases progressively with the amplitude of annual 5-7%.And the city is used for sanitary fund input every year, does not comprise that capital construction project just reaches about 1,000,000,000 yuan.Just become the focal issue that country and citizen are concerned about so how rubbish to handle, whom pays garbage fees by.It is reported that Pekinese's domestic refuse every year is fallen as the refuse treatment this growth with 6% speed increment, 15 of the landfill yards that need construction day treating refuse is 1000 tons, year is taken up an area of 1000 mu, and annual not including collected, transported, and only the expense of sanitary landfill is just up to 1.5 hundred million yuan.And the annual environmental sanitation funds in the whole city have only more than 100,000,000 yuan of Renminbi, if handle in the burning mode, then need tens00000000 yuan every year.Even Beijing is like this, the annual 1.3 hundred million tons of rubbish that produce of National urban, its handling will be an astronomical figure.
The object of the present invention is to provide a kind of domestic refuse of utilizing to make concrete and production technique thereof, it can be on a large scale, change municipal wastes into resource at low cost.
Technical scheme of the present invention is achieved in that garbage concrete, it is characterized in that: the components by weight percent of described garbage concrete is: rubbish 50-85%, binder 15-50%; Binder is made up of magnesia unslacked, halogen sheet or halogen powder, water and adjustment agent, and the weight percent of this binder is: magnesia unslacked 52-58%, halogen sheet or halogen powder 20-25%, water 20-25%, adjustment agent 0.5-2%.
The technology of garbage concrete, it is characterized in that: the water that with the binder components by weight percent is 20-25% is dissolved to the solution that degree Beaume is the 23-28 degree with halogen sheet or the halogen powder of 20-25%, the adjustment agent that adds 0.5-2% then, deployed solution being added to stirs in the magnesia unslacked of 52-58% again makes binder, add the binder mixing and stirring in the rubbish after will handling at last, make garbage concrete, its components by weight percent is rubbish 50-85%, binder 15-50%.
The binder of this garbage concrete is mainly selected low-cost ore deposit raw material magnesia unslacked and salt byproduct halogen sheet or halogen powder for use, not only associativity is good, and low price, production technique is simple and easy to do, different proportionings according to binder and rubbish, it can be widely used in the making roadbed, make wave resistance stone, artificial hillock etc., for realizing low cost, handling municipal wastes on a large scale a new approach is provided, thereby fundamentally solved the problem of municipal wastes, and municipal wastes need not classification, need not the huge investment of country, and no new municipal wastes produces.This technology is that the city composting is made raw material, by biological, Chemical Physics Processing, generates useful materials nuisanceless, no regenerated waste.This rubbish novel material is nontoxic, harmless, tasteless, light weight, inexpensive and of many uses, and ultimate compression strength can reach 2-8Mpa as required.Concrete as:
1, builds road foundation
" garbage concrete " builds road foundation, is one of main path that consumes on a large scale municipal wastes.The road model of having done from us detects through the expert, its intensity far surpasses the requirement of strength of the above High-Grade Highway Subgrade of the desired one-level of national highway department, permeability performance is good, the ultimate compression strength height, and performance and effect can replace original rubble, flyash etc. fully.Through calculating, the annual only rubbish in urban district, Shanghai just can be built more than 200 kilometer of 50 meter wide, the highway subgrade of 30 cm thicks.
2, river, river, sea wall
With the river sea wall that " garbage concrete " built, because the inside of dykes and dams is identical with surperficial intensity, be an integral body, pile up as megalith and form.In addition, this material alkali resistant corrosive nature is better, and in seawater, performance is become better and better over a period to come.So such river sea wall intensity will be considerably beyond the river sea wall of building with sandy soil and stone.
3, wave resistance stone
A large amount of wave resistance stone all will be thrown in the national fishing shelf of coastal dike, to reduce the destruction (particularly harbour, harbour) of wave to sea wall.Our " garbage concrete ", intensity is more and more higher in seawater, adapt to alkaline condition especially, and cost also is significantly less than the wave resistance stone of cement system.
" garbage concrete " can replace other material of construction such as stone, yellow sand fully, is applied to build road foundation, river, river sea wall and wave resistance stone.Like this municipal wastes of enormous amount under low-cost, extensive, no regenerated waste, the prerequisite easily implemented again, is converted into the useful materials that is used for urban construction through processing, has realized that municipal wastes turns waste into wealth, and becomes a kind of favourable renewable resource.
