S10. recycle, collect the biogas, natural pond slag and the natural pond liquid that produce in the second organic matter fermentation process and recycle.
Below above-mentioned S1 ~ S10 is described in detail respectively.
In step S1, first precrushing is carried out to collected changing food waste, its object is to carry out preliminary fragmentation to the object of comparatively large vol in changing food waste, so that follow-up process.The object of large volume mainly comprises: bone, plastics bag, plastics tablecloth, beverage bottle, pop can, bottle, ceramic soup ladle and dishes etc.Particularly, precrushing can carry out fragmentation by Horizontal double roller crusher.Be provided with thicker blade in this Horizontal double roller crusher, the distance between blade is configured such that discharging size is not more than 50mm.
In step S2, the object of the changing food waste through precrushing process being carried out to first time press filtration is, isolates the inorganic contaminants such as the plastics bag in changing food waste, plastics tablecloth, beverage bottle, pop can.Particularly, first time press filtration in by arranging screen cloth, the rubbish being greater than mesh opening size can be separated.Consider the beer bottle cap containing metal material in changing food waste, its quality is comparatively hard, and in order to protect screen cloth, the size of sieve screen apertures is set to larger than the size of beer bottle cap.Preferably, sieve screen apertures diameter dimension is 30mm.By first time press filtration, preliminary part inorganics is separated out, for follow-up further separation is prepared.
In press filtration process, the inorganics that size is greater than 30mm is separated, cannot by the sieve screen apertures of screen cloth, and the inorganics separated can be recycled.Remaining inorganics is mainly beer bottle cap, glass cullet slag, broken ceramic plate etc.And diameter is greater than to the organism of 30mm, and under press filtration, the organism that size is less than 30mm can be broken into further, and mixed in together with remaining first inorganic impurity.
In step S3, the object of carrying out solid-liquid separation is that the You Heshui in the changing food waste after by step S2 process separates.Particularly, in solid-liquid separation process, directly by screen cloth oil-water separation, and insufficient.So when solid-liquid separation, need to spray hot water to the first inorganic impurity of the first organism and bulk.So, on the one hand, under the effect of jet water course, the first organism and the first inorganic impurity can spread out; On the other hand, under the flushing of hot water, the grease that can remove comparatively thoroughly in solid-state changing food waste.Especially in the winter time, grease is in curdled appearance, thus grease must could be separated fully with hot water injection.Above-mentioned sprinkling hot water can adopt spraying plant, and it ensureing that hot water spray is comprehensive while, also can reduce the usage quantity of hot water.Less hot water usage quantity not only can save energy, and can reduce the treatment capacity of later stage oily water separation.
In addition, compared with prior art, the solid-liquid separation in step S3 carries out solid-liquid separation when changing food waste material grains is relatively large, grease is removed.So, both can ensure the thoroughness of solid-liquid separation and the adequacy of grease removal, the content of tiny organic particle in the oil-water mixture separated can also be reduced, be convenient to the separation of follow-up oil-water separation system to grease.
In step S4, the object of oily water separation is separated with water by the grease in oil-water mixture.Thus, for further processing to isolated grease, make biofuel and recycle.Isolated clear water directly discharges after treatment., isolated organic particle is collected, to carry out follow-up inoculation fermentation meanwhile.Meanwhile, because the organism in oil-water mixture is mainly short grained organism, so isolated organic particle is short grained organism in this step, it directly can be delivered to subsequent inoculations fermentation step and process.
In step S5, the object of magnetic separating is by the irony separating substances in the second organism and the first inorganic impurity out.This irony material is mainly beer bottle cap etc.Before magnetic separating, the second organism and the first inorganic impurity, under the washing away of hot water, can spread out equably.Thus when magnetic separating, irony material can be separated fully, can recycle for the irony material separated.
In step S6, due to through magnetic separating process, in remaining second organism and the second inorganic impurity, substantially do not contain metallic particles.Thus crusher can be utilized to carry out depth crushing, and the blade of crusher can not be damaged.During depth crushing, adopt screen cloth to sieve, in described depth crushing, the diameter of the sieve screen apertures of screen cloth is preferably 8-10mm.
In step S7, the object of second time press filtration is the second organism and the second inorganic impurity are separated from each other.Thus isolated second inorganic impurity carries out landfill disposal, isolated second organism is collected, and is convenient to follow-up inoculation fermentation.Particularly, second time press filtration will be greater than the separating substances of mesh opening size out by arranging screen cloth.Preferably, in second time press filtration, the gravel size decision of sieve screen apertures is less than 5mm.
So, when carrying out second time press filtration, because the size in the second organism and the second inorganic impurity is about 8-10mm, only need less squeeze it can be less than the sieve screen apertures of 5mm from size for the second organism to extrude, and need larger power just it can be less than the sieve screen apertures of 5mm from size for the second inorganic impurity to extrude.So, the second organism can be separated with the second inorganic impurity by controlling squeeze.Meanwhile, through the second organism of the sieve screen apertures of 5mm, its size is less than or equal to 5mm, and the organism under this size can be fully utilized in subsequent inoculations fermentation, produces more biogas.
In step S8, for collecting isolated organism in oily water separation step and second time press filtration step, be convenient to follow-up inoculation fermentation.This is because inoculation fermentation needs to carry out just having higher economic worth under a certain amount of organism prerequisite, therefore needs to collect organism.When the organism collected reaches a certain amount of, the organism of collection can be transported to downstream disinfection, receive the organism of upstream simultaneously again, proceed to collect.During sterilization, the mode by heat carries out disinfection to the organism collected, thus kills unwanted bacteria, for inoculation fermentation bacterial classification is prepared.
In step S9, after organism sterilization, and be cooled to thermophilic, can inoculate it.During inoculation, organism is stirred, thus realize the abundant inoculation of fermented bacterium.Postvaccinal organism is transported in fermentor tank and ferments, and in fermenting process, the parameters such as control temperature, PH, pressure, air content, ensure the generation of the environment optimum biogas in fermentor tank.
In step S10, the biogas of generation can contain CO
2, H
2, CH
4deng gas, thus need to purify to biogas, to meet the requirement of marsh gas power generation or gas component.For the biogas produced in fermenting process and natural pond slag, need be first separated by whizzer, then solid-state natural pond slag can be used for agriculture production as solid-state bio-feritlizer; Liquid natural pond liquid, after deacidification, concentration, generates liquid biological fertilizer and is used for agriculture production.
