Technical field

The invention belongs to technical field of waste treatment, specifically, being related to a kind of dry fermentation processing method of organic waste.

Background technique

Organic waste refers to decomposable organic substance part in daily life rubbish.Organic waste include swill, Dish root, dish leaf, animal hoof, angle, melon skin, fruit bits, eggshell, fish scale, eggshell, hair, diseases on plant stalk, leaf, weeds, animal corpse Body, excrement of animals etc..Organic waste should be responsible for collection by special messenger, and collection vessel must seal, have lid, antiseep, flyproof, prevent Mouse.Organic waste has two big sources: garden garbage and rubbish from cooking.Garden garbage: the collection of branch is in fluffy；It is leaf, miscellaneous Grass and plant are put in crate.Rubbish from cooking: it puts in polybag or violates and put in bucket with cover (bucket of 2 ~ 3L).Organic waste, Especially rubbish from cooking, it is desirable that it is high to collect the frequency than other compostings.

Organic waste has the characteristics that perishable, calorific value is low, the content of organic matter is abundant, and conventional landfill and burning are difficult to It deals carefully with.Currently, in the prior art, being badly in need of a kind of dry fermentation processing method of organic waste.

Summary of the invention

The purpose of the present invention is to provide a kind of dry fermentation processing methods of organic waste.

Its technical solution is as follows:

A kind of dry fermentation processing method of organic waste, comprising the following steps:

Step 1, garbage classification remove Harmful Waste, recycle beneficial non-organic rubbish, the organic waste after selecting is transported to Handle workshop；

Step 2 carries out spray process, and is passed through air, carries out Aerobic Process for Treatment, is analyzed in real time biogas component；

Step 3, exhaust air deodorization are then fed into biogas pipeline, finally reach gas distributing system；

Step 4, anaerobic fermentation, the biogas residue after fermentation, are produced into organic fertilizer.

Further, in step 1, the beneficial non-organic rubbish includes metal, is equipped with apparatus for recovering metal, metal recovery Afterwards, melt processed is carried out.

Further, it in step 2, carries out also needing organic waste carrying out pulverization process before spray process.

Further, the biogas in step 3 is also connected with solar energy heat-collecting system.

Further, in step 4, the temperature of anaerobic fermentation is 40-50 DEG C.

Further, in step 4, the time of anaerobic fermentation is 10-13d.

Further, in step 4, then the biogas residue after fermentation generates organic fertilizer by disinfection, dry, granulation, packaging.

Further, it in step 4, carries out disinfection at 80-90 DEG C.

Further, in step 4, the time of disinfection is 20-30min.

Beneficial effects of the present invention:

The dry fermentation processing method of organic waste of the invention can safely and effectively be handled organic waste, and may be used also With waste utilization, by treatment process biogas and biogas residue make full use of, saved the energy, reduced costs, be suitble to push away Wide application.

Specific embodiment

Technical solution of the present invention is described in more detail With reference to embodiment.
