The invention discloses a kind of rubbish fermentation techniques, comprising the following steps: a separation step sorts rubbish using mechanism for sorting, and sorts out the rubbish containing the non-dissolved organic matter of 15%-20%；The rubbish containing the non-dissolved organic matter of 15%-20% is carried out spontaneous fermentation, obtains fermentation intermediate product by spontaneous fermentation step；Biological bacteria fermentation step, spray of the addition containing probiotics strain carries out biological bacteria fermentation in the fermentation intermediate product, obtains organic fertilizer.Rubbish fermentation technique disclosed by the invention, rubbish during the fermentation will not knot tying be conducive to the fermentation of rubbish at mud, and can effectively retain and increase the organic matter in rubbish, so that the organic fertilizer quality that rubbish fermentation generates is higher.
Description
Technical field
The present invention relates to field of garbage disposal more particularly to a kind of rubbish fermentation techniques.
Background technique
With the rapid economic development of China, city numbers and population are dramatically increased, and city size and range constantly expand,
During urbanization process is accelerated, the yield of domestic waste also increases constantly, and in these urban life rubbish
Have in rubbish 50% the above are remaining meal rubbish, organic matter more abundant is contained in the inside, how these house refuses is carried out resource
Change recycle be field of garbage disposal a key subjects, wherein by rubbish fermentation at organic fertilizer by way of fermentation
It is one effective mode of recycling municipal solid waste.
Currently, the country, which converts garbage into organic fertilizer, is usually used high temperature anaerobic fermentation, high temperature anaerobic fermentation, hair
For ferment temperature at 100 DEG C or more, which has been easily destroyed the organic matter of fertilizer, causes the organic fertilizer quality of finished product not high；
And since the content of remaining meal rubbish in these domestic wastes is higher, namely containing more moisture, so that the process of fermentation
Middle rubbish is easily collected on one piece, and knot tying is at mud, so that garbage decomposition is not thorough, the organic fertilizer quality for generation of fermenting is not high.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention discloses a kind of rubbish fermentation technique, existing by rubbish to solve
The not high problem of the organic fertilizer quality formed of fermenting.
The present invention adopts the following technical scheme that realization:
A kind of rubbish fermentation technique, comprising the following steps:
Separation step sorts rubbish using mechanism for sorting, and sorts out and be dissolved with containing 15%-20% is non-
The rubbish of machine object；
The rubbish containing the non-dissolved organic matter of 15%-20% is carried out spontaneous fermentation, is sent out by spontaneous fermentation step
Ferment intermediate product；
Biological bacteria fermentation step, spray of the addition containing probiotics strain carries out biological bacteria in the fermentation intermediate product
Fermentation, obtains organic fertilizer.
It preferably, further include operating as follows in the spontaneous fermentation step: during spontaneous fermentation, described in stirring
Rubbish containing the non-dissolved organic matter of 15%-20%.
Preferably, during the stirring rubbish containing the non-dissolved organic matter of 15%-20%, contain to described
The rubbish of the non-dissolved organic matter of 15%-20% is crushed.
Preferably, the spontaneous fermentation step carries out in the environment of temperature is 70-80 DEG C, humidity is 60%-80%RH,
And its fermentation time is 20 days.
Preferably, it is additionally provided with secondary separation step between the spontaneous fermentation step and the biological bacteria fermentation step,
The secondary separation step is included in sorting in the fermentation intermediate product and eliminates the non-dissolved organic matter, is not contained
The rubbish of the non-dissolved organic matter, the biological bacteria fermentation step are to the rubbish without containing the non-dissolved organic matter
It adds the spray containing probiotics strain and carries out biological bacteria fermentation.
Preferably, further include operating as follows in the biological bacteria fermentation step: during biological bacteria fermentation, stirring
The fermentation intermediate product after adding the spray.
Preferably, the biological bacteria fermentation step temperature be 35-45 DEG C, humidity be 60%-70%RH in the environment of into
Row, and its fermentation time 15 days.
Preferably, the spray is that 1% probiotics strain, 3% wormwood, 2% benefit are added in 1000 ml deionized waters
Brittle Falsepimpernel Herb, 2% Pemisetum flaccidum Griseb and 4% dandelion fermented formation.
Preferably, the rubbish fermentation technique further includes sorting grinding steps after the biological bacteria fermentation step: right
The organic fertilizer is sorted and state of pulverizing.
Preferably, in the spontaneous fermentation step, the rubbish, which is laid in fermentation plant, to ferment；In the life
In object bacterium fermentation step, the fermentation intermediate product, which is laid in fermentation plant, to ferment.
Rubbish fermentation technique provided by the invention, which passes through, successively passes through spontaneous fermentation and biological bacteria fermentation for the rubbish of collection,
Two kinds of fermentation process do not need to carry out auxiliary heating, will not destroy the organic matter of fertilizer, can effectively remain fertilizer
Organic matter, so that the organic fertilizer quality of finished product is higher；Secondly, the 15-20% that rubbish is retained before being fermented by sorting
Non- dissolved organic matter, on the one hand which can increase gap between rubbish, efficiently control rubbish fermentation process
In humidity, and oxygen can be fully penetrated into rubbish by gap, is conducive to the thorough fermentation of rubbish, so that generating
Organic fertilizer quality is higher；On the other hand the non-dissolved organic matter for containing 15%-20% by the rubbish that sorts out of setting, can be to prevent
Only rubbish knot tying is conducive to the progress of rubbish fermentation at mud, more especially for remaining meal rubbish and summer melon and fruit peel content
It is easy the rubbish for being coagulated together knot tying into mud；In addition, by adding the spray containing probiotics strain in rubbish, on the one hand
Probiotics strain in spray can remove harmful to organic fertilizer corrosion bacterium, fungi and anthrax-bacilus in rubbish；On the other hand,
By adding probiotics in rubbish, the beneficiating ingredient in rubbish can be increased, so that the organic fertilizer product that the rubbish fermentation is formed
Matter is higher.
Detailed description of the invention
Fig. 1 is the flow chart of rubbish fermentation technique provided in an embodiment of the present invention；
Fig. 2 is the flow chart of spray preparation method provided in an embodiment of the present invention.
Specific embodiment
