Embodiment
[0082] Adopt the township refuse and sewage treatment system of the embodiment of the present invention, concrete implementation process is as follows:
[0083] For the 100t / day township waste treatment project, the township waste is supplied to the bag breaking machine through the apron feeder (with a processing capacity of 5-30t / h) for bag breaking, and then supplied to the roller crusher for crushing to obtain pellets. Garbage particles with a diameter of about 50mm are transported to the magnetic separation device by a screw conveyor for magnetic separation and separation, so that the iron in the garbage is separated and recycled, and the remaining garbage is then supplied to the vibrating screen with a sieve hole of 40-50mm for screening , the inorganic matter in the garbage, such as bricks and stones, is separated from the sieve and landfilled (20 tons / day to remove inorganic impurities), while the small organic waste containing organic matter in the garbage is separated ...

Abstract
The invention discloses a system and method for treating garbage and sewage of towns. The system comprises a town garbage pretreatment device, a town sewage filter device, a flotation acidification device, an anaerobic fermentation device, a dehydration device and a turning device, wherein a town garbage inlet, an organic garbage outlet and an inorganic garbage outlet are formed in the town garbage pretreatment device, a town sewage inlet and a separation liquid outlet are formed in the town sewage filter device, and an organic garbage inlet, a separation liquid inlet, a light material inlet,an organic liquid outlet and a heavy material outlet are formed in the flotation acidification device; the organic garbage inlet is connected with the organic garbage outlet, the separation liquid inlet is connected with the separation liquid outlet, and an organic liquid inlet, a biogas outlet and a biogas residue outlet are formed in the anaerobic fermentation device; the organic liquid inlet isconnected with the organic liquid outlet, a biogas residue inlet, a dehydrated residue outlet and a sewage outlet are formed in the dehydration device, and the biogas residue inlet is connected withthe biogas residue outlet; and a dehydrated residue inlet and an organic fertilizer outlet are formed in the turning device, and the dehydrated residue inlet is connected with the dehydrated residue outlet.
Description
technical field [0001] The invention belongs to the field of resource utilization of solid waste, and in particular relates to a system and method for treating township garbage and sewage. Background technique [0002] Township waste includes domestic waste generated daily by township users, including conventional kitchen waste, plastics, paper, slag, scrap iron, construction waste, etc. It has complex components and many types, and is perishable, prone to harmful bacteria, and emits odor. odor and other environmental pollution. [0003] At present, townships and villages below the county level have poor classification awareness, which affects end-of-life disposal. For example, waste with low calorific value when end-of-life incineration of domestic waste has a great impact on overall efficiency. Leachate is likely to be generated during landfill disposal of domestic waste, resulting in a sharp increase in leachate production in summer, increasing the operating cost of the ...
