Abstract
The invention discloses a fermentation material preparation method for biomass wastes of cities and towns. The method comprises the following steps of: treating a carbon source material, treating a nitrogen source material and mixing the carbon source material and the nitrogen source material. The biomass wastes are divided into the carbon source material and the nitrogen source material according to components, and the carbon-nitrogen ratio of the biomass wastes is balanced, so materials which can be subjected to high-temperature aerobic fermentation further can be prepared; various wastes can be treated simultaneously, and the biomass wastes can be prevented from polluting environment; and extra carbon sources or nitrogen sources are not needed to be added in a treatment process, the balance is performed only by the biomass wastes, and the method is simple and practical.
Description
Technical field
What the present invention relates to is waste disposal method, specifically is a kind of cities and towns biomass waste fermentation materials collocation methods.
Background technology
Along with the continuous growth of cities and towns scale and population, the quantity of rubbish is also in rapid increase, and wherein biomass waste proportion in the townm refuse total amount is increasingly high.Biomass waste contains salt (changing food waste), pathogenic microorganism (ight soil, mud), sterilant, worm's ovum and harmful heavy metal; And be prone to corrupt; It is the hotbed that disease and mosquitos and flies grow; The noxious that decay process discharged causes severe contamination to atmosphere, soil and water body, does not do harmless treatment, with serious harm cities and towns and peripheral ecotope, hygienic condition and people ' s health.Therefore, need biomass waste in the cities and towns is carried out harmless treatment.
The cities and towns biomass waste mainly contains: mud, city inland river lake and the piping shaft mud that changing food waste, water treatment produce, human and animal excreta, garden garbage (fallen leaves, beta pruning and recovery flowers and plants) etc.Fermentation method is at present the cities and towns biomass waste to be carried out one of innoxious, that minimizing is handled main method; Through being handled, waste makes the material that can ferment; Turn waste into wealth; But treatment facility often only to the biomass waste of single variety, reach fermentation materials science carbon nitrogen proportioning, also need increase extra auxiliary material.For example, usually use a large amount of agricultural stalks as fermenting carbon source and moisture adjuster in the sludge fermentation, garden garbage is handled and is used the aquaculture feces of livestock and poultry as fermentation nitrogen source.And cities and towns biomass waste itself just possesses the needed carbon nitrogen source of fermentation, self balance of obtain raw material from the outside before, can going ahead of the rest.Therefore, need to attempt a kind of collocation method that only makes fermentation materials with biomass waste.
Summary of the invention
The objective of the invention is provides a kind of cities and towns biomass waste fermentation materials collocation method to the problems referred to above; Solve the biomass waste that only is directed against single variety when utilizing waste to produce fermentation materials at present; Carbon-nitrogen ratio is uneven, also need increase the extra carbon source or the problem of nitrogenous source.
The present invention realizes through following technical scheme: a kind of cities and towns biomass waste fermentation materials collocation method, this method comprise the processing of carbon source material, the processing of nitrogenous source material and the mixing of carbon source material and nitrogenous source material, and concrete steps are following:
A, the carbon source material of water cut≤30% (weight ratio) is ground into the particle that particle diameter is 2～50mm;
B, with the nitrogenous source material dewatering of water cut>=80% to≤80% (weight ratio);
C, carbon source material and nitrogenous source material particles mix, and make mixed material C/N ratio 25～35:1, and water cut is 40%～60% (weight ratio).
Described carbon source material is a garden garbage.
Described garden garbage is selected from fallen leaves, beta pruning and flowers and plants.
Described nitrogenous source material is selected from mud, city inland river lake and the piping shaft mud and the human and animal excreta of changing food waste, water treatment generation.
As of the present invention further preferred, comprise also in the processing of described nitrogenous source material that nitrogenous source material with water cut≤30% (weight ratio) is ground into the particle of particle diameter for≤10mm.
As of the present invention further preferred, also comprise after the mixing of described carbon source material and nitrogenous source material adding the water step, make that solids content is 8%～15% (weight ratio) in the mixed material.
Adopt the positively effect of technique scheme: the present invention is divided into carbon source material and nitrogenous source material with biomass waste according to composition; Carbon-nitrogen ratio through to biomass waste self carries out balance; Make the further material of high-temperature aerobic fermentation; Can handle multiple waste simultaneously, prevent the biomass waste contaminate environment; Do not need extra increase carbon source or nitrogenous source in the treating processes, only carry out balance with biomass waste self, method is simple and practical.
