Abstract
The invention discloses a kind of Disposal of Domestic methods, its method includes treatment of urban garbage-green organic waste disposition, municipal refuse and organic waste are carried out classification disposition according to respective characteristic early period by this method, once reaching certain disposition stage can joint disposal, on the one hand rubbish targetedly can effectively be disposed according to garbage property, prevent secondary pollution, the joint disposal in another aspect later period can be improved the disposal efficiency of rubbish, save cost of disposal, so that the significant effect of refuse disposal is promoted, it is suitble to the disposition of high-volume rubbish.
Description
Technical field
The present invention relates to field of garbage disposal, more particularly to a kind of Disposal of Domestic method.
Background technique
China human mortality is numerous, and many rubbish are often manufactured in life.If these rubbish are unable to get the meeting of being effectively treated
Cause very big problem of environmental pollution.Currently, various rubbish carry out classification disposition according to its characteristic, general organic rubbish is adopted more
It is handled with the mode of fermented manure, the mode that solid inorganic rubbish mostly uses landfill to burn is disposed.On the one hand it is their respective businesses
Refuse disposal mode limit the disposal efficiency of rubbish, on the other hand extensive disposal options are unfavorable for the recycling benefit of rubbish
With.
Such as a kind of household garbage dewatering fermentation stacking method of CN201610901757.7, belong to technology of garbage disposal neck
Domain.The length and height for making full use of garbage pool stack raw material (admission rubbish) using garbage pool side is fixed, improve garbage pool
Using storage capacity, clean out garbage pool adit for draining in the other end of garbage pool, keep low level operation, open up into furnace rubbish
Material charging region, in the case where gravity squeezes, the rubbish for being dehydrated fermentation of rubbish heap lower part is squeezed out to material charging region, and by rubbish heap
In water squeeze out, in-line arrangement puddle from garbage pool draining double-edged fine-toothed comb discharge.By storage number of days of the rubbish in garbage pool, summer is maintained
7 days or more fermentation dewatering times, winter maintenance 10 days or more fermentation dewatering times.Decrement of the present invention to house refuse
Change, recycling, innocent treatment procedure are played the role of conclusive；Make full use of the capacity of garbage warehouse, i.e. length, width, height
Degree improves rubbish inventory, extends the time of stacking fermentation dehydration of the rubbish in garbage warehouse.
Above-mentioned patent carries out domestic rubbish disposal, the rubbish kind that this disposal options can be disposed using the mode that fermentation is stacked
Class is less, and using compost disposition, then treating capacity is smaller completely, and garbage treatment efficiency is lower.
Therefore, it is to sum up told, the present invention proposes a kind of Disposal of Domestic mode, preceding using the processing mode of composite type
Phase is respectively handled according to garbage property, and the later period is centrally disposed, and improves the efficiency of garbage disposal.
Summary of the invention
A kind of Disposal of Domestic method, the method step include:
(1) treatment of urban garbage: the municipal refuse of collection is placed in rubbish pit by weighing, is turned by crane or grapple
Enter to stop 3-4 days progress prior fermentations in fermentation tube, is sent on double sieve pore rotary screens and is sieved after fermentation, obtain partial size and be less than
30mm material, is greater than 180mm material at 30-180mm material, and wherein 30-180mm material is selected metal object conduct by magnetic separation and followed
Ring resource, for surplus material together with 180mm material is greater than directly as recyclable rubbish progress waste energy, partial size is less than 30mm
Material obtains partial size less than 10mm material and weight waste by double bounce screens；
(2) green organic garbage treatment: the green organic waste for receiving fortune weigh, and it is comprehensive broken to be placed on formation in crusher
Broken dry and wet substance, will form comprehensive broken dry and wet substance and mix with partial size less than 10mm municipal refuse and be placed in fermentation tube in crusher
It is stopped 6 weeks in road, transfers in mature storehouse and stop 4 weeks, be finally transferred to outer platform and sieved, chosen partial size and be less than 30mm
Material carry out compost be stored in external memory storage area, partial size be greater than 30mm material is disposed together together with weight waste.
Preferably, the method for step (1) prior fermentation is homogeneous-anaerobic fermentation-dehydration.
Preferably, the homogeneous is to be disposed municipal refuse progress homogeneous to average grain diameter 300mm using homogenizer.
Preferably, the anaerobic fermentation is that municipal refuse is sent in fermentation tube and carries out anaerobic fermentation, fermentation divide cold stage,
Hot stage and middle thermophase.
Preferably, the cold stage fermentation is 15-20 DEG C of temperature, the time 1 day；Hot stage fermentation is temperature 45-60
DEG C, the time 1-2 days；Medium temperature stage fermentation is 25-35 DEG C of temperature, the time 1 day.
Preferably, the dehydration is exposed to the sun wind 5-7 days, for the rubbish after fermentation is placed in open place until its water
Content is divided to be lower than 15%.
Preferably, the fermentation of step (2) the Green organic waste is that will integrate broken dry and wet substance to be placed in fermentation tube
In road, is kept for 28-40 DEG C of temperature, continue 6 weeks.
Preferably, the maturation of step (2) the Green organic waste is that the synthesis after fermentation is crushed dry and wet substance to set
25 DEG C of temperature are kept in mature storehouse, humidity 45% is for 4 weeks.
The utility model has the advantages that method includes treatment of urban garbage-green the present invention provides a kind of Disposal of Domestic method
Organic waste disposition, municipal refuse and organic waste are carried out classification disposition according to respective characteristic early period by this method, once reach
Certain disposition stage can joint disposal, on the one hand targetedly can effectively dispose rubbish according to garbage property, prevent
Secondary pollution, the joint disposal in another aspect later period can be improved the disposal efficiency of rubbish, cost of disposal be saved, so that at rubbish
The significant effect set is promoted, and is suitble to the disposition of high-volume rubbish, and the method for step (1) prior fermentation is homogeneous-anaerobism hair
Ferment-dehydration, the homogeneous are to be disposed municipal refuse progress homogeneous to average grain diameter 300mm, the anaerobism hair using homogenizer
Ferment is sent in fermentation tube for municipal refuse and carries out anaerobic fermentation, and fermentation divides cold stage, hot stage and middle thermophase, described low
Thermophase fermentation is 15-20 DEG C of temperature, the time 1 day；Hot stage fermentation is 45-60 DEG C of temperature, the time 1-2 days；Middle thermophase
Fermentation is 25-35 DEG C of temperature, and the time 1 day, the rubbish after fermentation is was placed in open place by the dehydration, and be exposed to the sun wind 5-7
On the one hand it can degrade to the harmful substance in rubbish until its moisture content is lower than 15% by the fermentation step,
So that the harmful substance toxicity in rubbish reduces or Non-toxic, on the other hand become soft by rubbish form of fermenting, particle
Partial size becomes smaller, and easily facilitates subsequent disposition, and the fermentation of step (2) the Green organic waste is that will integrate broken dry and wet object
Matter is placed in fermentation pipeline, is kept for 28-40 DEG C of temperature, is continued 6 weeks, and the maturation of step (2) the Green organic waste is will
Synthesis after fermentation is crushed dry and wet substance and is placed in 25 DEG C of temperature of holding in mature storehouse, and humidity 45% is for 4 weeks, and this method is on the one hand
For the harmful substance in green organic waste of degrading, basis on the other hand is provided for compost, so that garbage as resource.
