Description
Technical field
The invention belongs to technical field of waste treatment, and in particular to a kind of processing method of municipal refuse.
Background technology
The mankind constantly expand to natural resources exploitation and Li Yong in scale and intensity, consume the speed of resource also big
It is big to accelerate, civilization on the one hand is brought to society, people's quality of life is improved, on the other hand also implies that and accelerates rubbish
Increase, and rubbish is one of major reason of environmental pollution, if let drift, negligence of management and processing, it will result in
Public hazards, destroy ecological environment, injure the health of people, substantially there is the following aspects：
Dumping not only occupies cultivated land, and goes back contaminated soil and crops, because chemical products content is more come in rubbish
The even upper a century of many decades adds toxic component and heavy metal with which, these arable lands all without degraded after height, landfill
Use value is just lost, rubbish oozes drip polluted underground water through rainwater or enters surface water, causes water pollution, 80% stream
Row disease is all therefore propagated, and causes rivers and lakes severe depletion of oxygen eutrophication, coastal waters red tide；Rubbish during corruption,
Produce a large amount of heat energy, mainly ammonia, the pernicious gas such as methane and hydrogen sulfide, excessive concentration carries out stench, severe contamination air,
Heat is distributed, city is surrounded from aerial, rubbish will spontaneous combustion, self-destruction phenomenon；Polybag, plastic cup and foam plastic product etc.
White pollution is not easily decomposed, and is not only reduced city look and feel, environmental sanitation level, is lured harmful animal, have an effect on soil texture,
Cause soil to deteriorate, contain crop growth, make the plant underproduction；Hazardous waste is directly or indirectly detrimental to health, such as useless lamp
Pipe, particularly waste oil paint, refuse battery, because containing heavy metal substances such as mercury, cadmium and lead in battery, mercury has strong toxicity,
Lead can cause neurological disorders, ephritis etc., and cadmium mainly causes kidney, hepatic injury and bone disease-osteoporosis, rickets and fracture, put
Penetrating property can be carcinogenic.
Therefore, it is necessary to study a kind of processing method of municipal refuse, the danger of municipal refuse can be farthest reduced
Evil.
The content of the invention
Not enough in order to overcome present in background technology, the present invention proposes a kind of processing method of municipal refuse, can be by
The organic matter that can ferment carries out degradation treatment, and factor of created gase is higher, and resource utilization is high.
The present invention is achieved through the following technical solutions：
A kind of processing method of municipal refuse, comprises the following steps：
1) sort
Municipal refuse raw material is fed through in separator, can ferment organic matter and the inanimate matter that can not ferment is sub-elected；
2) crush
By the organic matter crusher in crushing of fermenting sub-elected；
3) ferment
Will it is broken after the organic matter that ferments add in fermentation tank, and add zymotic fluid, lipase and cellulase,
It is 50-65 DEG C to control fermentation temperature, and pH is 6-8, and ferment 40-50h；
4) product is handled
The biogas that fermentation is produced is transported to biogas center, and biogas slurry and biogas residue are discharged after being post-processed.
Further, the particle diameter of crusher in crushing is 500-800 mesh.
Further, step 3) in, described zymotic fluid is acetic acid and the mixture of hydrochloric acid.
Further, the mass concentration of described acetic acid is 30-35%.
Further, the mass concentration of described hydrochloric acid is 40-45%.
Further, the volume ratio of described hydrochloric acid and acetic acid is 1-3:1.
Further, step 3) in, the volume ratio of described zymotic fluid, lipase and cellulase is 3-4:2-3:1.
Further, when handling degradable organic matter, zymotic fluid, lipase and cellulase weight sum are rubbish weight
The 10-12% of amount.
Compared with prior art, the present invention at least has one of the following advantages：
1. municipal refuse is sorted, degradable organic matter can be handled by degrading, non-degradable inanimate matter
Handled by other means again, it is to avoid municipal refuse is directly handled without sorting and handles incomplete drawback.
2. adding zymotic fluid, lipase and cellulase during the fermentation, the same of municipal refuse degraded is enabled to
When, leaf brought into etc. is also degraded well；
3. the present invention is defined to the additional proportion of zymotic fluid, lipase and cellulase, enabling to ferment has
The degradation rate of machine matter is higher, and factor of created gase is high so that municipal refuse is turned waste into wealth, and resource utilization is high.
