Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
The embodiment of the invention sees that above-mentioned Fig. 1 is to shown in Figure 2.A kind of organic waste high-temperature aerobic fermentation process of the present invention is as follows: organic waste, handle through the waterpower pulverizer, and biodegradable material can be ground into homogenate and make the biological fermentation raw material.Owing to be under hydraulics, thus not only biological organic substance can be made homogenate, and to the bigger stone of some proportions, silt, glass, metal etc. because of gravity settling is discharged from the bottom, light materials such as plastics etc. float on the surface and are removed.Wet separation is efficiency of separation height not only, does not have airborne dust simultaneously and produces, and environmental pollution is little, and waterpower is pulverized can carry out sorting comparatively completely to the foreign material in the organic waste.Through the homogenate that the waterpower pulverizer is handled, simultaneously processing parameter is adjusted, make pH be in 6-9, C/N is in 12: 1-30: between 1, solid content is controlled at about 6%～12%; Enter the one grade fermemtation jar then, make one grade fermemtation jar slurries be warmed up to 40 ℃～60 ℃ by heating unit, return ripe slurries (the containing a large amount of advantage thermophile bacteria) inoculation in 10%～20% second order fermentation jar then, the enzyme of thermophile bacteria activates rapidly at 40 ℃～60 ℃ quilts, simultaneously aeration and stirring.After inoculating successfully, homogenate is transported to the second order fermentation jar.
In the second order fermentation jar, add trace element, strengthen accelerated fermentation processes.Thermophile bacteria utilizes organic matter to carry out metabolism, growth and breeding fast.Because metabolic further reinforcement, the heat of the spontaneous generation of thermophile bacteria metabolism make temperature continue to rise, and are degraded fully up to organic matter, in the fermenting process, the temperature of second order fermentation jar can reach 75 ℃-90 ℃, whole fermentation process about 40 hours consuming time-72 hours.
After the fermentation ends, sophisticated fermented liquid through the diagrid screening, is separated a small amount of not tiny foreign material (as pericarp, shell etc.) of fully fermenting, and these foreign material can be back to the waterpower pulverizer again and further ferment.Fermented liquid passes through solid-liquid separation again, and the mud cake of acquisition is through moisture eliminator, tablets press processing, and to become solid content be 90%～95% solid-state bio-organic fertilizer to packing at last.Filtrate then concentrates the liquid bio-organic fertilizer that becomes solid content 20%～35% through settling vessel sedimentation, vaporizer.
Because during the fermentation, homogenate stopped 40 hours being higher than under 60 ℃ the temperature at least, can reach and eliminate pathogenic bacteria fully.Therefore, do not contain pathogenic bacteria in the fertilizer.Bio-organic fertilizer is uniform and stable, inclusion-free, contains a large amount of beneficial microorganisms and nutritive element, the growth of these microorganism group energy strongly inhibited phytopathogens.
This technology belongs to aerobic fermentation, and the foul smell amount of generation is few, by easy biofilm treatment system, can reach discharging standards.
This technology can be handled various organic wastes effectively, comprises food waste, animals ight soil, from the residual organic substances of food-processing and municipal sludge etc.
The organic waste high-temperature aerobic fermentation; mainly realize by following processing unit: organic waste via the removal of impurities of waterpower pulverizer pulverize make homogenate, again by the high-temperature aerobic bacterium act on the one grade fermemtation jar, the second order fermentation jar carries out thermophilic fermentation; degradation of organic substances; again via diagrid screening foreign material; pass through solid-liquid separating equipment; the mud cake drying device, the tablets press production that obtain obtain SOLID ORGANIC fertilizer, and filtrate obtains liquid organic fertilizer through settling vessel, vaporizer production.
