The biological harmlessness and recycling treatment technology of organic refuse comprises the following steps of 1, carrying out sorting, 2, feeding the sorted organic refuse into a high-temperature tumbling drying device and carrying out pre-drying so that the moisture content of the organic refuse is reduced by 80%, 3, feeding the pre-dried organic refuse into a crushing system and crushing the pre-dried organic refuse into particles having sizes less than 5 millimeters, 4, feeding the particles into a biomass burning decrement furnace (BBDF), and carrying out great decrement of the organic refuse by a high-temperature drying anaerobic technology, 5, feeding slag obtained by the step 4 into a high-temperature disinfection drying furnace (H-DBDF) so that the slag output by the BBDF is subjected to full drying disinfection, and 6, directly applying the treated slag as soil mulches to nursery stocks and gardens, or carrying out further accurate grinding and choiceness of the treated slag, wherein the selected slag is utilized as an organic fertilizer. The biological harmlessness and recycling technology process of organic refuse has the advantages that 1, organic refuse is processed into a raw material of an organic fertilizer and then is recycled; 2, toxic gas is not produced in the whole process so that secondary pollution on the environment is avoided; 3, combustible gas is produced in processing, can satisfy energy requirements of the technology, is suitable for civilian use and has a low cost.
Description
Technical field
The present invention relates to a kind of organic waste treatment process, relate in particular to a kind of resource, minimizing of organic domestic waste, innoxious correct handling technology.
Background technology
The main processing means of house refuse are landfill and burning at present, all are unscientific for organic domestic waste with above-mentioned dual mode still.
If direct landfill, then organic domestic waste needs the time of decades to carry out natural degradation just can to settle out at last.In these processes decades, constantly have the discharging of percolate and greenhouse gases, thereby environment is caused secondary pressure.Along with country integrates with to sewage and waste gas emission standard and international advanced country, to this part percolate and treatment of waste gas cost significantly (＞800%) rise.And after landfill yard is closed, still need be for handling the expense of percolate and toxic emission payment great number.
If directly burn, then organic domestic waste contains a large amount of moisture, and combustion heat value own is not high, makes rubbish fully burn and the emission compliance of Shi bioxin in order to reach normal furnace temperature, must mix coal dust or sprinkle diesel oil.And in fact this technology is not through burning the biological energy source of rubbish of living of midwifery back and forth, but utilizes fuel (coal, diesel oil etc.) heat to burn organic domestic waste.In practical application, the electric energy that original equal fuel can be sent since thrown in contain a large amount of organic domestic wastes after, final electric energy output only should the output electric energy about 50%.Therefore, organic domestic waste gets into garbage burning factory and does not meet the recycling economy requirement.
Because organic domestic waste content accounts for more than 50% of total house refuse amount; Therefore, no matter use landfill still to burn, all can cause these two construction scales to be exaggerated; Big city of reducing day by day in the landfill soil and coastal developed regions, the cost of building garbage burning factory is very high.Therefore, effectively decrement and recycling treatment organic domestic waste seem significant.
Summary of the invention
Technical problem to be solved by this invention provides a kind of harmless biological, recycling treatment process of organic waste.
1), sorting the present invention solves the technical scheme that its technical problem provides, and mainly may further comprise the steps:; 2), predrying, organic waste after the sorting gets into high temperature tumble dry device, carries out pre-dried, makes the moisture of organic waste descend 80%; 3), get into crushing system, the organic waste particle is crushed to below the 5mm; 4), get into biological burning decrement stove (BBDF), reclaim the bio-energy of organic waste fast through high temperature drying anaerobism technology, realize organic waste decrement significantly; 5) get into high-temperature sterilization drying oven (H-DBDF), can make the abundant dry sterilization of slag of BBDF output; 6), be used for the mulch of gardens, nursery stock through the material after the above-mentioned processing, perhaps further correct grinding, selected back make organic fertilizer.
Further, described BBDF device mainly produces CH4 and H2 combustible gas, and this part gas passes through the Industrial Boiler device to the needed energy of the biological burning of BBDF device loopback, and outside system, exports domestic energy.
The invention has the beneficial effects as follows; 1), rubbish has become the raw material of organic fertilizer; Recycling: after organic waste was handled through this technical process, moisture was evaporated, organic matter is by Anaerobic Treatment, rubbish weight near initial 10%; Become harmless organic matter simultaneously, can be used as the raw material of making organic fertilizer.2), whole process do not produce toxic gas, to the environment non-secondary pollution: through the high temperature anaerobic technology, the gas of generation is CH4H and H2 fuel gas in BBDF, to not pollution of environment.3), the energy recycles; Cost is low; Utilization rate is high: organic waste produces CH4 and H2 fuel gas through the high temperature anaerobic technology in BBDF, can the burning energy be provided to BBDF on the one hand through the Industrial Boiler device, also can the burning energy be provided to the resident on the other hand.
The specific embodiment
Below in conjunction with embodiment the present invention is described further; A kind of harmless biological of organic waste, recycling treatment process; 1), sorting mainly may further comprise the steps:: before house refuse is classified; The composition more complicated, the screening installation through the input port is provided with carries out ragging to stone, glass, metal etc.; 2), predrying, organic waste after the sorting gets into high temperature tumble dry device, carries out pre-dried, makes the moisture of organic waste descend 80%; 3), get into crushing system: dried organic waste is through behind the crushing system, and the organic waste particle is crushed to below the 5mm, for next step processing is prepared; 4), get into biological burning decrement stove (BBDF): in biology burning decrement stove, realized the decrement significantly of organic domestic waste through high temperature drying anaerobism technology by the organic waste particle after pulverizing.The BBDF device mainly produces CH4 and H2 combustible gas.This part gas passes through the Industrial Boiler device on the one hand to the needed energy of the biological burning of BBDF device loopback, and the opposing party's system-oriented is exported the unnecessary civilian energy that supplies outward; 5) get into high-temperature sterilization drying oven (H-DBDF): the slag after handling through BBDF, also have small amount of moisture, biological aspect is complete stability not also, need send into the high-temperature sterilization drying oven again and carry out high temperature drying, sterilization treatment; 6), the material after handling through above-mentioned steps, directly be used for the mulch in nursery stock, orchard, perhaps further correct grinding, selected back make organic fertilizer.
