Description
Technical field
The present invention relates to changing food waste handling process, more particularly to a kind of domestic organic garbage recycling treatment process.
Background technology
With the continuous improvement of exhausting level, the fast development of industrial and agricultural production level, town and country organic waste is (wherein
Organic waste, agricultural stalk garbage including people and cultivation fowl and animal excrement etc.) discharge capacity increasingly increase.According to statistics, in
The annual municipal domestic organic refuse yield of state is more than 3.1 hundred million tons；Annual agricultural stalk yield more than 6.5 hundred million tons, annual animal dung
Just more than 2,600,000,000 tons, China has become organic waste output country maximum in the world to yield.At present, domestic and international organic solid
Waste treatment mainly has 3 kinds：Landfill, burning and biological treatment.Land landfill can cause the pollution of soil and high soil
Ground contamination restoration harness expense, burns not only high cost, and the exhaust emissions of castoff burning technique can produce dirt to environment
Dye, these processing methods cause serious problem of environmental pollution while organic waste is processed.Although organic waste has
The harm of pollution, but it simultaneously again can be as important resource by recycling.Not only containing a large amount of in organic waste
The nutrient such as organic matter, N P and K, also containing amount and the trace element in other such as more calcium, agricultural fertilizer can be processed into,
And feces are used as fertilizer Chinese long-standing.Organic waste is agricultural can not only to solve pollution problem, and right after applying
Soil physics, chemistry and biological character have certain improving effect.Therefore, the agricultural also field of organic waste for China
It is the most feasible, the most suitable disposal method, reclaiming organic waste is using the development also complied with Chinese current national conditions
Trend.
Aerobic compost is to make mineralization Organic substance, humification and innoxious and become rotten by fermentation under microbial action
The process of ripe fertilizer, can generate available nitrogen, phosphorus, the potassium compound that can be absorbed and used by plants in a large number, and can also synthesize
New macromolecule organic --- humus, it is the important component of organic fertilizer, is also the important substance for constituting soil fertility.
Organic waste is processed by aerobic compost and organic fertilizer is produced, is the weight that organic waste harmless treatment and Fertilizer Transformed are utilized
Want approach.Additionally, also occurring in that on market using special microbial bacterial agent is come special fermentation process organic waste and production has
Machine fertilizer, this handling process is significantly improved in Traditional compost mode：Risen using aerobic fermentation equipment and increase rubbish
The quantity of beginning microorganism is accelerating the fermentation of material, final output fertilizer.
At present, all there is Organic substance decomposition in the processing mode that either aerobic compost still carries out aerobic fermentation using equipment
Slowly, long processing period or fermentation period is short but material process not exclusively, the low problem of product fertilizer efficiency.Meanwhile, existing rubbish
Rubbish handling process generally ignores the secondary pollution problem that by-product in garbage processing procedure (waste gas, waste water) is caused to environment.
Further, since there is the phenomenon of heavy metal severe overweight in the house refuse of each department at present, and existing garbage treating process
In ignore substantially heavy metal presence hazardness, directly results in heavy metal severe overweight in output material, final fertilizer is again
Cause the transfer of water and soil pollution, heavy metal that serious pollution is caused to environment again using in soil, more endanger our people
The health of class.
The content of the invention
For the problems referred to above, the invention provides a kind of organic waste recycling treatment process, organic waste is carried out it is solid,
Liquid separating treatment, different material difference resource, improves organic waste resource degree, during reduction handling process
Emission and the heavy metal ion in solid material and liquid is eliminated respectively realizing at utmost reducing organic garbage treatment work
Pollution problem of the skill to environment.
The technical solution used in the present invention is：
A kind of domestic organic garbage recycling treatment process, comprises the following steps：
(1), domestic organic garbage is poured on realization on the pigeonholes with solid-liquid separator through collecting, measuring hypsokinesis of weighing
Preliminary solid-liquid separation, liquid outlet of the liquid from below pigeonholes is discharged, while manually rejecting on pigeonholes macroscopic

(2), the domestic organic garbage after pigeonholes initial gross separation sorting enters horizontal conveying belt, domestic organic garbage
Tiling is taken in horizontal transmission to scatter, can again be sorted and reject the non-organic thing being hidden in domestic organic garbage；
(3), after horizontal conveying belt, into climbing conveyer belt, the top of conveyer belt of climbing is arranged domestic organic garbage
There is spray irrigation device, by the metal cation for being sprayed the oil stain and adhesion that can reduce domestic organic garbage surface,
During domestic organic garbage is delivered up, the free water in domestic organic garbage relies on self gravitation certainly to climbing conveyer belt
Dynamic backflow, the liquid outlet from below pigeonholes is discharged；
(4), domestic organic garbage is transported in pulverizer after conveyer belt of climbing and carries out crushing/dewatering, is lived organic
Rubbish directly falls in the squeezing dewatering machine of lower section after crushing/dewatering, by unnecessary in squeezing removing domestic organic garbage
Moisture, and domestic organic garbage half-dried after squeezing is transported in high-temperature aerobic fermentation chamber, pulverizer and squeezing dewatering machine
The moisture of removing is discharged by the discharge outlet immediately below squeezing dewatering machine；
(5), in high-temperature aerobic fermentation chamber, half-dried domestic organic garbage is organic under the conditions of high-temperature aerobic after squeezing
Rubbish fermentation microbial inoculum fast decoupled ferments；
(6), by domestic organic garbage by fermentation after output object take out from high-temperature aerobic fermentation chamber, be directly stacked at
Natural secondary biofermentation is carried out in compost groove；
(7), the material that natural secondary biofermentation completes to obtain is sieved, the thick material that will be unable to sieve is returned to
Fermented again in high-temperature aerobic fermentation chamber, to sieving after thin material carry out organic fertilizer detection, by detect it is not up to standard
Material is returned to and carry out in compost groove continuation natural secondary biofermentation, and the material to reaching organic fertilizer standard is packed,
Obtain the SOLID ORGANIC fertilizer of finished product；
(8), the moisture that the discharge outlet immediately below the liquid outlet and squeezing dewatering machine below pigeonholes is discharged is admitted to oil
Oil-water separation, isolated oil and organic wastewater are carried out in water separation device, oil can be used to manufacture biodiesel or iundustrial oil；
(9), the isolated organic wastewater of oily-water seperating equipment is sent in sedimentation tank, and a huge sum of money is added in sedimentation tank
Category ion precipitation agent, the heavy metal ion in organic wastewater is deposited in pool bottom sludge, so as to remove organic wastewater in weight
Metal ion, the supernatant in reprecipitation pond is sent in Aeration tank, adds organic waste aerobic fermentation microbial inoculum to enter in Aeration tank
Act charitably aerobe fermentation, obtain fermentation liquid；
(10), fermentation liquid is sent into and carry out in concentration tower high temperature concentration, kill microorganism remaining in fermentation liquid, while steaming
The moisture for sending out unnecessary, concentrates the nutrient substance in fermentation liquid and collects；
(11) take the fermentation liquid after concentration to be detected, fermentation liquid not up to standard is sent in Aeration tank and proceeds to send out
Ferment；
