Description
Technical field
The utility model belongs to refuse treatment plant, is specifically related to a kind of solid-liquid separately and refuse disposal installation that organic matter and inorganic matter separate.
Background technology
China is one of the most serious country of Problem of Urban Waste in the world.
According to statistics, National urban house refuse annual production: be 1.15 hundred million tons the eighties, has reached 1.43 hundred million tons (are only second to the U.S., occupy the second in the world) nineties;
National urban rubbish is stacked total amount over the years up to 7,000,000,000 tons at present, and generation is every year with approximately 8.98% speed increase.Dumping accounts for the soil gross area and has reached 500,000,000 square metres, approximately amounts to 750,000 mu of arable lands;
In more than 600 big and medium-sized cities, the whole nation, have 70% by rubbish, to be surrounded, have a strong impact on urban development and periphery resident's living environment.
China's garbage disposal adopts the methods such as traditional landfill, compost, burning to process at present substantially, and above-mentioned traditional technology of garbage disposal exists well-known defect:
One, garbage compost is processed
It is to utilize microorganism to decompose the Biochemical processes of rubbish organic principle that garbage compost is processed.In biochemical reaction process, organic matter, oxygen and bacterial interactions, separate out carbon dioxide, water and heat, generates humus simultaneously.
The shortcoming that garbage compost is processed has three:
1, the stone in rubbish, metal, glass, plastics the like waste can not be decomposed by microorganism, these discarded objects must go-no-go out, otherwise processed;
2, the garbage compost cycle long, floor space is large, garbage compost field periphery sanitary condition is poor;
3, fertilizer efficiency is low, cost is high, sales difficulty, deficiency in economic performance.
It is the organic matter that can be decomposed by microorganism in rubbish that garbage compost is processed, so it is the treatment technology for organic principle in rubbish, rather than the final treatment technology to whole rubbish.
There is obvious shortcoming in garbage compost technology, can not process not putrescible organic matter and inorganic matter, therefore subtracts appearance, decrement and innoxious degree low.Therefore only rely on compost treatment still can not thoroughly solve garbage problem.At present in some places by consumer waste filling and embedding, by spontaneous fermentation, after the several years, excavate out again, sieve goes to be just used as fertilizer after the material of the without putrefactions such as plastics wherein and sells.In fact with this fertilizer raise fruit trees, vegetables and grain is dangerous, reason is the heavy metal (Pb due to not perishable organic component (paper, plastics, cloth, rubber etc.) in rubbish, Cd, H steals) content is very high, if it is underground that this class material and perishable organic matter are embedded in for a long time altogether, add the effect of rainwater, heavy metal will inevitably infiltrate in final organic fertilizer product, with this seed manure kind food content of beary metal out, must exceed standard, be detrimental to health.
Two, incineration treatment of garbage
Waste incineration is rubbish to be sent into incinerator carry out combustion process.After waste incineration, discharge heat energy, produce flue gas and solid residue simultaneously.Heat energy will reclaim, and flue gas will purify, and residue will digest, and this is the requisite technical process of burning disposal.
The shortcoming of incineration treatment of garbage:
1, in incineration firing process, discharge toxic gas, as mercuryvapour in dioxin, battery etc., the flue gas of generation must purify, and purification techniques difficulty is large, operating cost is high;
2, in incineration firing process, produce and account for original vol 20%-30% poisonous and harmful slag and dust, burn the poisonous and harmful slag and the dust that produce and also must process;
3, in rubbish, the resource of recoverable is destroyed, and is a kind of processing method of wasting resource;
4, burning disposal there are certain requirements rubbish Lower heat value, is not that any rubbish can burn;
5, burning facility one-time investment is large.
Three, garbage loading embeading
The shortcoming that garbage loading embeading is processed:
The rubbish of landfill does not carry out harmless treatment, residual a large amount of bacteriums, virus; The hidden danger such as biogas, heavy metal pollution also lie dormant; Its garbage leaching liquid is ground contamination groundwater resources for a long time also, so, this method potential greatly harm, can bring infinite future trouble to descendants.This method does not only realize the recycling treatment of rubbish, and a large amount of land occupation, and pollution sources are retained to descendants.Most critical be that each landfill factory and office reason is limited in one's ability, after filling up, still need the landfill yard that investment construction is new, further land occupation resource.Current many developed countries prohibite landfill waste.
Comprehensive analysis, the technology of garbage disposal that China adopts at present, does not have a kind of method can really realize the general objective of garbage as resource, innoxious, minimizing.
