Description

Reduction method of organic waste {A TRATMENT METHODS FOR REDUCTION OF ORGANIC WASTE}

The present invention relates to a method for reducing organic wastes such as food waste, livestock, flakes, and sludge in wastewater treatment plants, which are the main causes of soil, water, and air pollution, and more specifically, polyphenol aromatics to organic wastes introduced in composting lines. Microbial metabolite with essence is added to high concentration of corrosive and composted by fermentation to use as soil improving agent, and leaching effluent from organic waste is transferred to leachate treatment line and microbial metabolite with polyphenol aromatic essence The organic matter is decomposed by stirring with water and treated with active water to remove odors, as well as the deodorizing function, antimicrobial activity, and growth promoting function of the active water, which is used as washing water for transport vehicles, containers, etc. Is returned to the leachate treatment line to be used as raw material for biologically active water, and surplus of active water The powder is a method for reducing organic wastes, which effectively reduces organic wastes by an iterative process of spraying compost sand of composting lines to promote moisture control and fermentation of organic matter to remove odors.

In general, fermentation of organic matter and composting is a method that has been used by humans for a long time.

The composting of the conventional organic matter had a disadvantage that the bad smell odors and the pests swell during the summer season by leaving the compost grave on the yard, but there was not a big problem in the age of low population density.

However, with the recent increase in the population and the development of industry, the generation of various organic wastes such as food waste, sewage sludge, livestock waste, and manure is increasing, and the disposal of such organic wastes is very serious problem. have.

Landfill is the most commonly used method of treating such organic waste.

Such a landfill method has a disadvantage in that decayed leachate is generated and odor is severe, and the treatment of the leachate generated by polluting the groundwater and the surrounding river has a huge cost.

In addition, another method of treating organic waste is disclosed by a treatment line such as a high speed dryer and a fermenter, but there is a disadvantage in that effective treatment cannot be provided due to a lack of treatment facilities.

Thus, in recent years, various methods have been disclosed for composting or feeding organic wastes using the by-products while simultaneously treating such organic wastes.

However, as mentioned above, when the organic wastes are deposited for composting, leaching wastes are generated and their effective treatment is required.

Disadvantages in that a large amount of raw materials such as sawdust and rice husk are used for the artificial treatment of the leachate, and the processing cost is high.

Odor generation is not fundamentally eliminated, and in particular, the food waste has a high salt concentration, so even when reduced or composted, there was a disadvantage that it cannot be used as compost because of salt.

The present invention has been researched and developed to effectively solve the disadvantages of the conventional method for treating organic waste as described above,

1 is a schematic diagram illustrating a process of the present invention.

In general, the degeneration of organic matter in nature is directed in two directions.

That is, metamorphosis in two completely different directions, such as low molecular weight and high molecular weight, is occurring universally. Of the degenerations of these organic materials, which one is more common, it can be said to be the direction of high (macro) molecularization.

Degeneration to low molecular weight can be widely seen in the decay of organic matter in the form of enzymatic degradation, but in quantitative terms it is a very few.

On the other hand, the transformation into high molecular mass is a major transformation circuit occurring in the natural world, such as polycondensates of coal series such as coal, peat, peat, peat, etc. Inna lake's quality and countless.

The high molecular weight of organic matter in nature is caused by the physicochemical reaction of organic matter with metabolites, including compounds with phenols and / or phenol-exposed compounds, which are produced by aerobic bacteria and aerobic bacteria in common soil bacterial groups. to be.

In addition, when a substance containing a lot of activated silicic acid is administered to the reaction system, a corrosive reaction occurs and macromolecularization and oniization progress.

<Basic Reaction 1>

Organic matters (organic aqueous solutions and water-soluble organic mixtures) are rapidly bonded, granulated, aggregated, condensed, and polymerized by adding microbial metabolites including phenols and / or compounds with phenolic exposure groups to form macromolecules and bulk products. Make up.

<Basic Reaction 2>

When an appropriate amount of a substance containing a lot of activated silicic acid content is added to the reaction, a polycondensation reaction for corrosion occurs.

The above-mentioned compound having a phenolic exposure group refers to a general organic substance having a phenolic exposure group, but an enzyme having a phenolic exposure group is particularly effective.

In addition, a substance containing a lot of activated silicic acid refers to an unstable substance having high activity such as volcanic glass having a composition of andesite and rhyolite.

When the substance containing a lot of activated silicic acid in the reaction system of the basic reaction 1 is embedded or added, or when the raw water contains the same substance, for example, the synthesis of clay minerals in paper wastewater and pig wastewater All reactions in mineral extenders in the feed occur in the state of base reaction 2.

The difference between the basic reaction 1 and the basic reaction 2 is that the silicic acid powder is activated when the purpose of removing the inorganic ionic substance is that the reaction product is more prominent in the material produced in the basic reaction 2. It is beneficial to squeeze a substance containing a large amount into the reaction system. And it does not mean that the keylet structure does not develop in the reaction product by the basic reaction 1, but it is merely that the development of the keylet structure is accompanied by more technical difficulties.

On the other hand, since wastewater treatment plants and waste treatment plants are artificial environments, there are no silicic acid salts or corrosive substances present in the great outdoors, and even if they are trace amounts, they cannot be soil environments. Can't.

However, when it is assumed that the environment in which corrosive materials or silicate present in the waste water treatment waste disposal present organic matter contained in waste water are decomposed by microorganisms in an environment that is corrosive materials present in the soil CO _2, N _2, H Inorganicized with ₂ O, etc., various microbial metabolites, decomposition products of organic products, chelate products as resynthesis products, caking substances, etc. are agglomerated, condensed, agglomerated, polymerized, and polycondensed to be contained in waste water as the molecular weight increases. The organic material is removed from the liquid phase and simultaneously removed in the liquid phase by being combined in the form of various ionic substances, arrival compounds, internal compounds, and other organic-inorganic compounds contained in the waste water.

Odor molecules present in the ionic state in water are chelate products that trap (+) ions (eg NH _4, etc.) of the odor molecules as constituent molecules of the chelate and change to compounds different from their original properties to remove odors in this process. In addition, various antibiotics produced during the corrosive process sterilize pathogenic microorganisms, and microbial groups that are not affected by the antibiotics are promoted by biologically active substances.

However, in an artificial environment such as a wastewater treatment plant or a waste treatment plant where corrosives do not exist, organic substances are enzymatically degraded in a form of enzymatic decomposition.

As mentioned above, such a phenomenon is not a phenomenon commonly occurring in Mother Nature, but is sometimes a local phenomenon such as an early decay of a dead body of an animal, and mainly occurs in an artificial environment. The above reactions do not produce corrosive substances and microbial metabolites (chelate products, growth promoters, antimicrobial substances, etc.) having various aromatic qualities generated during the formation of corrosive substances do not produce odors and pathogenic bacteria. This is to be simmered.

Corrosion reactions of organic substances occurring in the great outdoors are very slow, taking 10 to 20 years in large areas. Even if there are corrosive substances or silicates in the wastewater treatment plant and waste treatment plant, the corrosive reaction is not completed. In order to take a very large area and a lot of time, economic efficiency is low.

In order to solve this problem, microbial metabolites with excellent activity and polyphenol aromatic qualities are found among the corrosive substances in the nature and processed again to produce strong polycondensation reactions. By repeatedly adding active silicates, which are more active than those present, to the point where the organics are introduced, the corrosion reaction can be accelerated more than what is happening in Mother Nature.

In other words, when microorganism metabolites with aromatic polyphenols are concentrated in a high concentration of environmental substances into the 'intestine of pollution', the microbial population that adapts to the 'intestine of pollution' is responsible for metabolic functions. They secrete metabolites that adapt to ie compounds with polyphenolaromatic essences, and pathogens that do not adapt are killed. On the contrary, if contaminants with high concentrations are continuously introduced into the 'cleaning place', the microbial population living in the 'cleaning place' will adapt to the 'cleaning place'.

Therefore, in order to maintain the sewage treatment plant at all times, it is necessary to repeatedly input highly concentrated material of microbial metabolite having poly phenol aromatic nature at the point of sewage input.

When the concentration of the substance having the polyphenol aromatic essence is weak compared to the input organic matter or when the input is stopped, the 'field of purification' is induced to the 'field of pollution'.

That is, when microbial metabolites having an aromatic nature of polyphenols are added to organic substances, they are aggregated and condensed to form macromolecules and agglomerates, where they are added by stirring and corroding rhyolite active silicates such as volcanic glass, which is similar to the average plasticity of surface elements. Reaction (soilation reaction) takes place and polycondensation occurs. (1985.UCHIMIZU)

In addition, in the artificial environment with or without free oxygen, phenolic metabolic function is expressed in soil anaerobic bacteria or bacterial groups composed of soil aerobic bacteria and anaerobic bacteria. Induction culture of microbial metabolic function is only possible in the presence of (metabolites comprising phenol or / and compounds with phenolic exposure groups).

To this end, as mentioned above, a metabolite including the phenol or / and a phenol-exposed compound or a substance containing the metabolite (such as a corrosive) is added, or a phenol-based metabolic function existing in nature This particular bacteriological group, which has been strengthened, and which has an official relationship with the soil-organic anaerobic bacterial group, should be used as a spawn under certain conditions.

That is, if only good spawns are available, it is feasible to induce the metabolism of the soil microbial group in the wastewater by phenol-based culture, but it is difficult to cultivate spawns.

However, as mentioned above, soil bacterial populations inhabiting soil generally express phenolic metabolic functions.

The most widely distributed substance containing phenolic metabolites is the soil itself. Soil is the end product of the reaction (corrosion reaction) caused by the action of phenolic metabolites on organic matter and silicates. The process material of the corrosion reaction is collectively referred to as corrosion precursors, corrosion precursors and mixtures of corrosion. Called corrosive, it is possible to say that good quality soil is the corrosive itself.

However, silicates are generally physicochemically stable substances, and the ratios of phenol-based metabolites, organic substances, and silicates are not overwhelmingly proportional to the progress of the corrosion reaction. As a result, the soil should generally be seen as a mixture of corrosive and silicate.

Corrosion precursors are generic terms of process substances in which various organic substances are changed to corrosion by the action of phenolic metabolites and silicates as described above. In other words, corrosion precursors are substances derived from phenolic metabolites and silicates. It will contain.

Therefore, the corrosive precursor, and moreover the corrosive, is said to contain a phenolic metabolite as described herein, but only the corrosive precursor functions as an inducer and culture material for the soil flora.

In the corrosive reaction, silicate is involved, and the average composition of the earth's crust in which the soil flora originated is granite or nitrite silicate, and it is alkalite, which is unstable or activated under surface physicochemical conditions. In the presence of volcanic glass, it is assumed that the high-quality corrosive layer with high content of corrosive precursors is relatively widely distributed in the special terrain of the andesite volcanic zone.

In addition, since the corrosives may be produced by synthesis, it may be more rational to use the corrosives rather than the use of spawn when culturing the metabolic function of the soil bacteria group to the phenolic system.

The present invention implements the method of purifying, that is, reducing organic waste, by applying the theory revealed by the studies of many scholars described above.

Organic waste (food waste) contains about 1 ~ 2% of salinity. If food waste is fermented and reduced to less than 10%, salt concentration, which is a stable compound, cannot be decomposed. Even if it falls out and becomes fermented, it cannot be used as compost because of salt.

Therefore, in order to realize the weight loss by composting the organic waste, it is possible only if the salt component of the compost is removed.

However, in the method of the present invention, since the generated compost is reduced by 30 tons of food waste (water content of 80%) to fermentation is reduced to 1.2 tons (water content of 50%), even if it is not utilized as compost, the weight loss effect is large (96% reduction).

Furthermore, the method of the present invention is that the seed compost produced in its own processing line is a concentrated substance of microbial metabolites having a polyphenol aromatic nature. By inducing the secretion of compounds having a family essence, the compost grave becomes an environment for natural purification, and the chilate structure of the microbial metabolite having a polyphenol aromatic nature is dissolved in water and hydrated, Na + and cl- It combines with Na + ions to form complexes or internal complexes (chilates) to form sodium sulphate, and cl − is combined with other organic compounds to change into constituent molecules of organic compounds other than NaCl.

Hereinafter, a preferred embodiment in which the organic waste reduction method of the present invention can be specifically carried out will be described in detail with reference to the accompanying drawings.

When the organic waste is input, the plastic bag is shredded using a conventional shredding device such as an opening machine.

The crushed organic waste is put into a water content control hopper (Hopper) and mixed with a seed compost to adjust the water content to 60 ~ 65% while controlling the organic content by the microbial metabolite having the polyphenol aromatic nature contained in the seed compost The metabolic function of the microorganisms inhabiting the waste is induced to secrete metabolites with the aromatic nature of polyphenols.

Odor generated from organic waste due to the soiling of such organic waste is removed.

The organic waste of which the moisture content is controlled is transferred to a compost yarn equipped with an diffuser to be deposited at a height of about 1.5 to 2 m for fermentation. When fermentation of organic waste starts, the temperature starts to rise and the temperature rises to 65 ~ 70 ℃ in about a week and then starts to fall. When the temperature starts to fall, the deposited compost tombs are agitated and deposited by payload, etc., and the temperature rises again, and when the temperature falls, the stir deposition is carried out again in the same manner as above. This stirring deposition is repeated three times to complete the fermentation process.

The fermentation is terminated by transferring the compost to the aged to take more than two months to take the process of producing a mature compost.

Filtering the compost deposited on the aging yarn in a sieve method (screen equipment, vibrating type, mesh type) by separating and removing the nail, glass pieces, vinyl pieces, etc. to produce a mature compost, part of the completed compost is the moisture content control step It is returned to the water content control to be used as the compost for the control, the remaining surplus of the aged compost is packaged to be used as the compost of the soil improver.

At this time, the leaching waste liquid (leached water) generated in the water content control step is transferred to the adjusting tank of the leachate treatment line and the microbial metabolite having the polyphenol aromatic essence conveyed from the settling tank is mixed and stirred with the highly concentrated concentrated sludge, and the leaching waste liquid. The metabolic function of the microbial population in the stomach is induced to secrete metabolites with the aromatic nature of polyphenols.

This soilification reaction removes the odor of the leachate by changing the environment of the adjustment tank into the environment of the great nature.

Transfer the soil-reacted leachate to the aeration tank to decompose the organic matter contained in the leachate into natural sedimentation in the sedimentation tank and separate the solid-liquid and transfer the supernatant to the discharge tank, and transfer the active water transferred to the discharge tank to the vehicle and The water used as the washing water of the transport container is returned to the control tank to be used as raw material for biologically active water, and the remaining active water is returned to the fermentation stage of the composting process of the compost manufacturing process and sprayed to the composting yarn to control moisture and remove odors. The process of using it for

At this time, a part of the precipitate sludge produced by the solid-liquid separation in the settling tank is transferred to the sludge tank to form a pellet and a material in which a highly concentrated microbial metabolic function having a polyphenol aromatic nature is concentrated into pellets. A compost manufacturing line or leachate treatment is carried out by a repetitive process that draws activated sludge from a reactor-filled reactor and returns a certain amount to the water content control step and the compost fermentation step of the compost manufacturing process and use it as a compost raw material. All the lines return the corrosives produced by corrosive organics in the presence of corrosion and utilize them in each treatment line to continuously produce compost of soil improver.

By this continuous process, the organics are all treated with corrosive and the leachate is purified with clean water.

In particular, organic wastes (food waste) are trapped in the chelate in the state of being hydrated with Na ⁺ and Cl ^- contained in them, and Na ions turn into sodium humate, and Cl ions combine with other organics to form new substances. The compost produced is a salt-free compost, which can be used as a soil improving agent.

As described in detail above, the present invention contributes to the environmental purification by effectively reducing the sludge of soil, water pollution and air pollution, food waste, animal waste, and sludge in the wastewater treatment plant, and the produced compost is free from salt damage. The economical efficiency is secured by utilizing the landfill of organic waste in a huge facility, and the use cost of organic waste is reduced.
