Under the condition, the organic domestic garbage can be subjected to high-temperature aerobic fermentation for 55-65 ℃ under the action of aerobic microorganisms, and the high-temperature fermentation is completed within 3-5 days, so that harmless and stable treatment of sludge is realized.
The properties of the municipal solid waste treated by the system are as follows: the water content is 45-60%; the content of organic matters is reduced to more than 200g/kg of dry sludge, the death rate of worm eggs is more than 95 percent, the bacteria value of faecal coliform bacteria is more than 0.01, and the relevant requirements of aerobic static composting treatment technical regulations of municipal domestic waste are met.
By adopting the continuous dynamic aerobic fermentation treatment system for organic wastes in the first embodiment or the second embodiment, the municipal domestic wastes can be treated, so that the treated products meet the stabilization requirement. As shown in fig. 3, the processing method includes the following steps:
under the control of a control subsystem of the treatment system, a conveyor of the treatment system pretreats the organic waste through a pretreatment subsystem of the treatment system;
conveying the pretreated organic waste into the aerobic fermentation drum through a conveyor for fermentation treatment, and outputting the fermented material;
and a control subsystem of the treatment system controls the running state of each device according to the data which is transmitted by the on-line detector and reflects the fermentation state of the materials in the aerobic fermentation drum to complete the continuous dynamic aerobic fermentation treatment of the organic wastes.
The pretreatment in the treatment method comprises the following steps: respectively conveying the auxiliary materials and the organic waste into a mixing bin of the pretreatment subsystem by a conveyor and mixing by a mixer in the mixing bin;
the mixed materials are temporarily stored in a mixing bin or conveyed to an aerobic fermentation drum.
The processing method further comprises the following steps: and (4) screening the output material after fermentation treatment in a screening machine to obtain undersize materials and oversize materials.
The treatment system can realize continuous and dynamic operation of the domestic waste aerobic fermentation system, shorten the fermentation time, greatly improve the treatment efficiency of the system, improve the treatment effect and realize harmless and recycling treatment of the domestic waste, including organic wastes such as kitchens and the like. Thereby solving the problems of long fermentation period, difficult process control, disjointed system control inside, lag feedback information, insufficient equipment reaction capacity, poor treatment effect and the like of the existing aerobic fermentation system.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
