Abstract
The present invention discloses a method for changing urban garbage into a resource without environmental pollution, which comprises the following steps: firstly, the garbage is biologically depredated by a biological degradation method or a high-pressure and high-temperature degradation method, and then, the garbage is respectively selected and utilized according to types by using a high-pressure blasting type gravity separation method. The method of the present invention basically ends the vicious circle of garbage damaging human living environment, and utilizes the garbage to produce biological organic compound fertilizer with high efficiency, fireproof building decoration products and high strength bricks and tiles without polluting groundwater, rivers, lakes, sea and land.
Description
The invention relates to a kind for the treatment of method for urban garbage, more particularly about a kind of daily-life garbage without environmental pollution, recycling processing method.
Rubbish is the human inevitable outcome that exists, and it is endangering human civilization and healthy always over the past thousands of years, is the No.1 killer at human beautiful home.
Municipal wastes also claims municipal solid wastes, it is meant the family domestic garbage that city resident's daily life abandons, and comprises organic and inorganic and the domestic refuse of eating with people, drink, accommodating to close and produces relevant industrial refuse (cinder, brick, watt, decoration garbage and trade waste etc.) and the general name of public place rubbish, environmental sanitation department road-cleaning thing (green plants remains as: lawn weeding, trees beta pruning, fallen leaves, paper product, plastics and dust etc.) and part building waste.
It is reported, world's refuse production average growth rate per annum reaches 8.24%, exceed 2.5～3 times of the average annual rate of growth of world economy, China city quantity developed into 668 in 1998 according to statistics, it is 1.46 hundred million tons that China's municipal wastes in 1996 is produced per year, the whole nation subtracts nearly 8,000 ten thousand mu only because of rubbish makes the soil, and nearly 10 years, surplus annual farmland of destroying because of rubbish reaches 750 ten thousand mu.Only Beijing's daily output in 1996 municipal wastes is about 1.4 ten thousand tons, now, China's municipal wastes just increases progressively with 8% annual growth, this rate of increase almost national economy annual growth with China is suitable, together with 6,000,000,000 tons of storages of the historical cumulative of China's municipal wastes, great majority are absorbed in the encirclement of rubbish in 668 cities of China, and these rubbish will cause the influence of reality and the harm of hiding in the hiding to soil, underground water, atmosphere etc., and urban ecological environment in havoc.
Contain various heavy in the rubbish, such as: copper, cadmium, chromium, mercury etc. and organic compound, be mostly poisonous and hazardous hazardous substance and the compound that is difficult to resolve in the middle of this, they permeate the ground together with rainwater, are polluting underground water, are polluting river, river, lake, sea; Polluting the water source of human existence since their strong toxicity, harm big, influence urban ecological environment and HUMAN HEALTH.
The air storage of municipal wastes, the carbonic acid gas of the Global climate change that under biological action, exerts an influence naturally and methane greenhouse gases, thereby Greenhouse effect are produced a very large impact, present global temperature is more and more higher, and the concentration of carbon dioxide content improves (improving 30% than the age that industrialization is produced) in this and the atmosphere much relations.
Rubbish is the source of ten thousand diseases, contains morbific bacterium of countless versions and virus in the rubbish, is directly endangering human life and health.
At present, the main method of countries in the world processing municipal wastes is: burning method, landfill method, composting process.
1, burning method
This method is that rubbish is watered the back burning electricity generation that oils.
Its subject matter is investment big (build the rubbish factory that burns 300 tons a day, invest 1.2 hundred million Renminbi, working cost is quite high).
It is that 400 tons garbage burning factory has melted more than 300,000,000 yuan of Renminbi unexpectedly that the Shenzhen builds a day output.
If promote this technology, there are not several countries that so big financial resources are arranged in the world.
In addition, the secondary pollution of burning away the refuse is serious, and the burning back produces the Dioxins carcinogenic substance, stays in the incineration plant surrounding resident, cancer patients's ratio is very high, though utilize the waste gas of incineration heating of can generating electricity, its price is high, it is little for overall income, and people's profit, state's profit all do not match, and are difficult to realize.
2, landfill method
This method is to dig pit or utilize natural hole landfill.
Landfill cost height (980 tons of rubbish were handled on 1st in certain big city, and landfill factory makes an investment of 50 million yuan, and the transfer point of wine made of broomcorn millet cover is invested about 100,000,000 yuan, adds up to 1.5 hundred million yuans).
Landfill produces inflammable gas, the time danger on fire from explosion is arranged, lunar lacus Southern Mountain sun one rubbish factory one blasted in 1994 8, and 1.5 ten thousand tons of rubbish are thrown sky, had destroyed the pump house and the sewage embankment at 40 meters outside the rubbish factory.So each landfill factory may explode at any time just as a buried biological bomb.
The harm of landfill maximum is the polluted underground water source, and grou1ndwater irrigation can not be got in the farmland, and people more unable to drink use.
Landfill takies a large amount of soils, and rubbish is unlimited, and the soil is limited, and mu landfill rubbish surplus China will abdicate 100,000 every year so goes down, and how many soils that we depend on for existence can also remain.
3, composting process
This method is that partial organic substances in the rubbish is used to do compost, and all the other are thrown away.
Shortcoming is that fertilizer efficiency is low, purity difference, and nuisance is many, and the peasant does not accept, sales difficulty, all the other rubbish of throwing away are contaminate environment still, and domestic most composting plants get into a difficult position, and therefore the composting plant of eastern suburb, Beijing Dong Cun just closes.
The objective of the invention is to overcome the defective of taking method treating refuse such as waste incineration, landfill, compost to exist, a kind of less investment, instant effect, no future trouble are provided, realize human lives's rubbish round-robin garbage harmless, resource utilization, nothing residue, ataxonomic treatment process.
This and other purpose of the present invention will and be described and further set forth by following detailed description.
