According to above-mentioned these public documents, can gem-purely see, refuse treatment has become the technical field that country attaches great importance to, but we also see that technology of garbage disposal also exists a lot of deficiencies, drawback and technological gap up till now simultaneously.
Make a general survey of other countries of the world, the very severe problem of the same existence of refuse treatment, especially developing country and relative poor and backward country, sanitary fill is as serious in mountain, environmental pollution etc., and problem becomes increasingly conspicuous, and needs the method treating refuse of employing science, efficient, environmental protection badly.
Waste disposal method mainly comprises burning disposal, sanitary landfill, sorting compost at present.Burning disposal and sanitary landfill, not only than great, are also the gesture of rising gradually, and the atrophy gradually of sorting compost, on the other hand, country is having little effect aspect publicity and propelling refuse classification processing, and this all makes refuse treatment difficulty strengthen.More outstanding, in prior art, all be there is to many defects in focusing on of rubbish, continue to cause secondary pollution to environment, the addressing of garbage burning factory more causes negative impact to social stability.Mainly there is following defect and problem in conventional garbage treatment process:
(1) burning disposal
1, gaseous emission, causes secondary pollution
Adopt the treating refuse of burning mode, conventionally need to add auxiliary fuel, such as the coal of 5-10%, not only increase cost, increase the discharge of carbon monoxide, sulfurous gas simultaneously, in burning, produced especially multiple obnoxious flavour in addition, environment has been caused to secondary pollution.Wherein to environmental influence the most outstanding be Dioxins, the toxicity of Dioxins is very large, is 130 times of prussiate, 900 times of arsenic, has the title of " poison in century ".Meanwhile, the problem that garbage burning factory all exists whole plant area to stink to high heaven, also has very significantly impact to the conventional air ambient of periphery.Exactly because incineration treatment of garbage has very serious impact to surrounding enviroment, having there is the Mass disturbance of a lot of mass protest government building waste incineration projects in the areas such as recent China Foshan, Zhejiang Hangzhou, affects very severe.
2, combustionresidue, still needs to take up an area landfill
Burning disposal rubbish can produce the combustionresidue of 20%-25%, and prior art is normally by extrusion molding landfill after residue harmless treatment, and this still will take a large amount of soils.Owing to containing heavy metal and other objectionable impuritiess in residue, treatment technology requirement is high, treatment facility is complicated, processing cost is high, if some incineration plant fully residue carry out harmless treatment or process not thorough, this will cause serious pollution can to again soil, underground water.
3, great number investment, economy return is very micro-
Burning disposal rubbish needs great number investment, the incineration plant that the treating refuse of 1 year is 300,000 tons need to invest 3.2 hundred million-3.5 hundred million, be mainly used in buying the equipment of large-area soil, complexity,, technical sophistication large in particular for the facility investment of harmless treatment emission gases and combustionresidue, generally will reach 50% of total investment for construction, this causes, and project cost is high, return period is long, reduced the economic benefit of the project implementation.More having indivedual enterprises is that the investment that interests reduce these treatment facilities does not by fair means or foul reach the effect of harmless treatment, brings very big hidden danger to surrounding enviroment and common people's health.
(2) sanitary landfill
Garbage loading embeading its by by stacking in refuse collecting or directly placing into the soil, rubbish is not carried out to harmless treatment, residual the hidden danger such as a large amount of bacteriums, virus, heavy metal contamination are imbedded underground in the lump; Its garbage leaching liquid can permanent ground contamination groundwater resource, and in seashore is built landfill yard in some areas, work the mischief to coastal waters water and marine organisms.Garbage loading embeading is not only wasted the required land resources of a large amount of landfills, and the environmental pollution causing, because Land pollution has disguise, hysteresis quality, and there is accumulation property, ununiformity, the most important thing is to have difficult reversibility, substantially be the process that can not reverse completely such as heavy metal hard degradation causes Land pollution, organic pollutant also needs the long period to degrade, and this all brings infinite future trouble to descendants.Current many developed countries prohibite landfill waste.The competent authorities at different levels of the Chinese government and technical specialist all think that this kind of mode treating refuse can not be lasting, but not yet find one prevent the pollution of the environment, the processing mode of high-efficient simple is replaced this type of processing mode again.
(3) sorting compost
Garbage sorting compost is the ability of decomposing by microorganism, and the organic substance decomposing in rubbish is become to inorganic nutrients, after compost treatment, becomes farm crop fertilizer, and inorganic metal object wherein and glass, fragment of brick etc. are carried out to landfill, and rubber plastic etc. reclaim; But consumer garbage compost amount is large, and the content of nitrogen and phosphorous is low, life-time service easily causes soil compaction and groundwater quality to degenerate, and also has following distinct issues: 1, odor pollution simultaneously; 2, working cost is too high; 3, technology is immature; 4, factory management is bad etc., so garbage sorting composting technology is still immature at present.
To prior art, retrieval is found, patent name is " using rubbish, stalk and mud to manufacture the method for environment-friendly renewable coal ", application number is 201310672617.3 Chinese invention patent, in this patent, rubbish, stalk, mud are made to environment-friendly renewable coal by weight mixing in mixer, but the course of processing adopts physical method raw material disposal not to be had to the variation of matter, the coal combustion value of its generation is low, pre-treatment link in manufacture method needs manual sorting, classification simultaneously, making method tradition, is difficult to Industry Promotion and sizable application; Patent name is " Novel household garbage environment-friendly renewable coal manufacture method and products thereof ", application number is China's invention of 201210076821.4, utilize domestic refuse to prepare reclaimed coal, but need to add a large amount of chemical auxiliary materials in preparation, cause serious secondary pollution to environment; In addition, also there is the example taking rubbish as fuel power generation function, coal gas processed etc. in China, but investment is large, cost is high, harmless treatment imperfection, forms secondary pollution, and some need to mix a large amount of raw coal or coal liquid, finally causes losing more than gain.
To sum up, also there is no the method for a real science, efficient, pollution-free treating refuse in prior art, more not having can be by rubbish in low cost, pollution-free situation, generates that fuel value is high, the production technology of the coal of non-secondary pollution.
