Recycling method of organic waste and eco friendly-high functional Neo Peat produced by the method}

The present invention relates to a method of converting organic waste into a resource, and more particularly, to a method of manufacturing an eco-friendly, highly functional artificial pit from organic waste such as food waste or sewage sludge.

Methods of treating organic waste vary from traditional landfill to recently popular composting. The general method of recycling organic waste has disadvantages such as frequent complaints around facilities due to various odors generated during the treatment process, and high treatment costs due to excessive wastewater treatment costs. Because of these difficulties, simple landfill or incineration is still widely used.

The method of converting organic waste into a resource according to the conventional technology is divided in various ways depending on the treatment process such as fermentation. For example, in Korean Patent Registration No. 10-1761911, organic waste is injected into a high-temperature aerobic fermentor, and pure oxygen or concentrated oxygen is supplied in the PSA (Pressure Swing Absorption) process. It is treated and composted.

In addition, Korean Patent Registration No. 10-1057475 proposes a microbial preparation having excellent composting and deodorizing ability and a method for manufacturing the same, as the activity of degrading enzymes against starch, fat, protein, and cellulose is evenly high and can be grown at high temperatures. Patent No. 10-1272187 introduces a method of decomposing food waste into a raw material for compost by mixing and stirring with microorganisms and sawdust.

In addition, Korean Patent Registration No. 10-0640181 states that by-products generated during the dehydration and stirring process of food waste are reduced to high-quality feed or compost, and the dehydrated condensate is used as its own functional deodorant and liquid manure ( Liquid fertilizer) or as a deodorant, and Korean Patent No. 10-1651373 purifies livestock manure and converts it into high-quality liquid manure, promotes rapid fermentation and decomposition using a step-by-step purification tank, and uses a deodorant liquid. It introduces a means of removing odor pollution and a method of producing quality energy methane.

As described above, the method of converting organic waste into a resource according to the prior art is to make compost by mixing agitation and fermentation using mainly microorganisms, sawdust, etc., or by dehydrating organic waste, so that the desorption liquid is liquid manure, odor remover, energy. It is being used as a resource by means of producing methane.

On the contrary, a method for producing organic waste into an eco-friendly, high-functional artificial pit (Neo Peat) has not yet been specifically developed.

The terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention.

However, reference numerals for the same or similar components throughout the drawings and embodiments will be used unified.

<Manufacturing method>

The method of manufacturing organic waste such as food waste according to an embodiment of the present invention into an eco-friendly high-functional artificial pit (Neo Peat) is a pretreatment step (S1), a raw material mixing step (S2), a biochemical calcium reaction treatment step (S3), It includes an anaerobic fermentation step (S4).

The organic waste to be treated in the embodiment of the present invention is food waste discharged from daily life, by-products from the process of running agriculture, forestry, livestock, fisheries, manufacturing or sales, sewage sludge, factory wastewater sludge, food factories Various such as sludge.

<Pre-treatment step>

The pretreatment step (S1) is a step of crushing a lump of organic waste such as food waste to make the particles even, and removing foreign substances such as vinyl, metal, and plastic mixed in the organic waste.

The pretreatment step is performed in a sorting crusher (not shown), and a grinder may be provided for crushing the lump. As for the sorting method, a variety of known sorting devices such as magnetic and vibrators can be used.

In the organic waste that has undergone the pretreatment step, large lumps exceeding a certain level are removed and foreign substances are removed, so that the process efficiency below the raw material mixing step described later can be increased.

<Material mixing step>

The raw material mixing step (S2) is a step of mixing at least one of reactive rice husk powder or rice husk powder with the organic waste that has undergone the pretreatment step (S1).

Here, the reacted rice husk powder or rice husk powder may be selectively added or mixed and added.

Reactive rice husk powder used in this step refers to a material produced by hydration reaction with quicklime using a biochemical calcium reactor described below.

Such reactive rice husk powder or rice husk powder helps to properly control the moisture content of organic waste.

More specifically, at least one of the reactive rice hull powder or the rice husk powder may be added in 10 parts by weight to 50 parts by weight based on 100 parts by weight of the organic waste.

Organic wastes such as food wastes that are put into the pretreatment step have a water content of 85% or more, but when the goal is to adjust the moisture content of the mixture of organic wastes that have gone through the raw material mixing step to a level of 70% to 75% The amount of rice husk powder or rice husk powder is limited to 10 parts by weight to 50 parts by weight based on 100 parts by weight of organic waste.

Here, the determination of the moisture content target of the organic waste mixture to 70% to 75% is to increase the working effect of the biochemical calcium reaction treatment step. At this time, if less than 10 parts by weight of reacted rice husk powder or rice husk powder is added, the biochemical calcium reaction treatment is difficult because the moisture content is too high, and if it is added in excess of 50 parts by weight, the water content is too small and the biochemical calcium reaction treatment step The rate of the hydration reaction is lowered, making it impossible to properly produce the desired "raw material".

Therefore, it is necessary to limit the reaction rice husk powder or rice husk powder introduced in the raw material mixing step to 10 parts by weight to 50 parts by weight based on 100 parts by weight of the organic waste.

The raw material mixing step may be performed in a conventional mixer. The mixing rotary blade provided inside the mixer can be mixed within about 1 hour at a speed of 5 to 10 rpm.

<Biochemical calcium reaction treatment step>

Meanwhile, the biochemical calcium reaction treatment step (S3) is a step of promoting a hydration reaction by mixing quicklime (CaO) with a mixture of organic wastes passed through the raw material mixing step (S2), and generating a "raw material".

The biochemical calcium reaction treatment step is carried out in a dedicated reactor within a short time. The reactor may be provided with a plurality of mixing blades or mixing screws to quickly mix the organic waste mixture and quicklime introduced through the previous step. The mixing blade or the like can be operated continuously while the hydration reaction is in progress, thereby further promoting the hydration reaction.

Specifically, FIG. 2 shows a reactor 100 provided with a pair of mixing blades 104 and 105 at a lower portion and one mixing blade 106 at an upper portion.

The lower pair of mixing blades 104 and 105 push organic waste from the inlet 101 to the outlet 103 while rotating from the inlet to the outlet, and the upper mixing blade 106 rotates from the inlet to the outlet. While doing so, the organic waste that cannot be mixed at the bottom and comes up to the top is additionally pushed from the input port to the discharge port.

However, when the rotation speed of the lower pair of blades 104 and 105 is 24 rpm or more, the upper mixing blade 106 may be excluded because organic waste and quicklime are completely mixed to cause a hydration reaction.

At this time, the rotational speed of the blades of the reactor 100 is appropriate if 24 rpm is appropriate, but it is effective if it is 18 rpm or more, and at a speed below that, there is only a stirring effect, so the hydration reaction is incomplete and the intended "raw material" is not well produced. .

The chemical reaction that proceeds in the biochemical calcium reaction treatment step is as follows.

As the quicklime reacts, carbon dioxide and heat are generated, and the organic waste is subjected to a hydration reaction at a temperature of 80°C to 120°C for 5 to 25 minutes in a short time. At this time, the treated product is in a state in which the odor is effectively reduced, and most of the pests are removed by the sterilization effect by the high temperature. In addition, precipitation water hardly occurs.

When quicklime reacts with moisture, the reaction is completed within 3 to 10 seconds, so the reaction time in the biochemical calcium reaction treatment step varies depending on the moisture content, but organic waste in the reactor is mixed and hydrated within 5 to 25 minutes with quicklime. The intended "raw material" is produced only after completion, and if the mixing and hydration reaction is exceeded for more than 25 minutes, the mixture of organic waste and quicklime is not homogeneous, so the hydration reaction becomes incomplete.

In addition, when the hydration reaction in the reactor, pests present in organic wastes such as food waste are mostly killed at 80 ℃ or higher, but if the reaction temperature is 80 ℃ or lower, the pests are incompletely sterilized. If the reaction temperature is higher than 120 ℃, the "raw material" is carbonized. And a product that cannot be used is created.

The heat of reaction generated during the hydration reaction in the reactor is formed by increasing the temperature to evaporate moisture, and by increasing the activity of organic substances to chelate metal ions such as calcium and Ca-organic compounds. At this time, the treated product immediately after the completion of the reaction rises to alkalinity (pH 11 to 12) by evenly dispersing and adsorbing calcium hydroxide particles to the organic material and the Ca-organic compound, thereby also killing pests and pathogens.

Particularly, the treated product immediately after completion of the reaction forms a granular structure while solidification proceeds. Accordingly, the odors remaining in the treated product are adsorbed to the granular structure of quicklime and are also adsorbed to fine pores such as calcium hydroxide and calcium hydrogen carbonate, so that odors and odors are secondarily completely controlled.

During the hydration reaction in the reactor, quicklime decomposes odor-causing substances such as cysteine, carboxylic acid, and amino acid as shown in the formulas below, and the treated product in a sol state is gelled. ) To reduce odor. In addition, some of the decomposed odor components form calcium compounds, which are easily dissolved in the soil, so that the crops can easily absorb them. Calcium component is an absolutely necessary component as a macro element comparable to nitrogen, phosphorus, and potassium in the soil, and the content of sugar (min) is increased by the synergistic effect of calcium components and the effect of using organic substances is improved.

In order to elicit the effect of this hydration reaction, the input amount of quicklime may be limited to 5 parts by weight to 25 parts by weight based on 100 parts by weight of organic waste.

If the amount of quicklime added during the hydration reaction is 5 parts by weight or less based on 100 parts by weight of organic waste, the hydration reaction does not occur evenly, and it is difficult to appropriately lower the water content of the resulting "raw material". If 25 parts by weight or more are used The resulting "raw material" becomes strong alkali (pH 12.5 or more), and the "raw material" is concreted due to excessive hydration, making it difficult to obtain the intended characteristics of artificial pit.

<Anaerobic fermentation stage>

The anaerobic fermentation step (S4) is a step of generating an eco-friendly, high-functional artificial pit (Neo Peat) by stirring and mixing an additive to the "raw material" produced through the biochemical calcium reaction treatment step to anaerobic fermentation.

Here, as an additive, at least one of natural peat, mushroom waste medium, coffee meal, coffee charcoal, rice husk powder, reactive rice husk powder, pozzolan, and dietary sulfur is used.

Natural peat refers to peat or peat, and has excellent moisturizing power, enabling continuous supply of nutrients. It has good ventilation and helps in respiration of the roots of crops. It contains nitrogen, phosphorus, and potassium, so it provides a trace amount of fertilizer after decomposition in the soil. Also, since it contains a large amount of organic matter, it is effective for the growth of useful microorganisms.

Natural pit is a carbonaceous substance with a carbon content of less than 60%, and a substance with a large amount of fiber is made by the beneficial metabolic activity of phenolic metabolizing microorganisms through anaerobic fermentation, and artificial pit is also artificial according to the method of pit formation. It is a carbonaceous material made of.

Mushroom waste medium refers to the by-products left after mushroom cultivation in mushroom cultivation farms. Mushroom waste medium contains a large amount of nutrients, so it has a beneficial effect on activating microorganisms and growing plants.

Coffee waste (粕, coffee waste) is the residue left after the coffee liquid is extracted from coffee beans, and it contains a large amount of organic components, which greatly contributes to the activation of microorganisms. Coffee charcoal is a semi-carbonization treatment of collected coffee leaf, and it is composed of porous carbon grains, so it has excellent odor removal effect and mineral supply effect.

Pozzolan is also called Ge-lite, and can be obtained by pulverizing volcanic ash, silicate clay, and silicate. It has the effect of removing odor and has the effect of supplying minerals.

Dietary sulfur (MSM) can be obtained by finely pulverizing earth sulfur discharged from the basement, and it is added to organic waste to supplement the insufficient sulfur (S) component.

These additives may be used alone or in combination of two or more components.

The additive is put into a stirrer and stirred and mixed. Here, the stirrer may be a conventional rotary stir fermenter having a simple structure.

The resulting "raw material" is mixed in a stirrer and then in a state where oxygen supply is blocked by the storage for 1 to 20 days in the yard, anaerobic fermentation and stabilization are performed, while the water content is 20% to 40% artificial pit Become (Neo Peat).

In order to form the aforementioned artificial pit (Neo Peat), the content of the additive may be limited as follows.

Additives introduced in the anaerobic fermentation step (natural peat, mushroom waste medium, coffee meal, coffee charcoal, rice husk powder, reactive rice husk powder, pozzolan, dietary sulfur, or a combination thereof) is 100 parts by weight of the "raw material" It may be limited to 10 parts by weight to 60 parts by weight.

When the additive is used in an amount of less than 10 parts by weight, there is a problem that it is impossible to control moisture according to the above-described water content (20% to 40%) level. On the other hand, in the case of using in excess of 60 parts by weight, the production cost is high, resulting in impractical use.

In the anaerobic fermentation step, calcium hydroxide and calcium hydrogen carbonate generate calcium carbonate through the following process, so when the artificial pit prepared in the present invention is used in the soil, it plays a role of neutralizing acidic soil.

In addition, through anaerobic fermentation after ripening for 1 to 20 days, it becomes an eco-friendly, high-functional artificial pit that maximizes the activation of phenolic metabolic activity microorganisms.

In general, sawdust used as litter for livestock takes 40 years to decompose, 10 years for coco peat and 3 years or more for rice husk, and sawdust and coco peat have the property of vomiting when moisture exceeds the volume. It is difficult to control the odor when used as.

The artificial pit produced in the present invention has a water content of 20% to 40%, so it is used as a moisture control agent for food waste treatment plants, livestock treatment plants, sewage sludge treatment plants, etc., and can be used as litter for livestock because it is decomposed within 2 to 6 months.

Here, the determination of the water content of the artificial pit prepared in the present invention to a level of 20% to 40% is to be easily used as a moisture control agent, and when used as a litter, the water content is preferably 35% or less, and should be 20% or less. In this case, it is due to the inconvenience of pelletizing or laying work.

In addition, as described above, the "raw material" immediately after undergoing the biochemical calcium reaction treatment step is solidified and forms a granular structure, so that the malodorous substances remaining in the treated product are adsorbed to the granular structure of quicklime and each step of the present invention It is a material that completely controls odors and odors by being adsorbed to fine pores such as calcium hydroxide, calcium hydrogen carbonate, calcium carbonate, etc., which are generated in the process, and when anaerobic fermentation and stabilization are additionally used, coffee leaves, pozzolans, etc., which have an odor removal effect It has excellent efficacy in removing odor.

In addition, it is manufactured by extracting minerals from human pit (Neo Peat) manufactured in the present invention in a non-polluting method such as Humite or Bentonite, so that liquid natural mineral water containing various kinds of minerals, microbial enzymes, etc. When added, it can be used as a soil conditioner.

As described above, according to the present invention, the treated product immediately after the end of the reaction in the biochemical calcium reactor becomes the alkaline (pH 11 to 12) "raw material", and includes natural peat, mushroom waste medium, coffee meal, coffee charcoal, Rice hull powder, reacted rice husk powder, pozzolan, and dietary sulfur are mixed, and anaerobic fermentation is performed for 1 to 20 days to make an artificial pit with a pH of 7.4 to 7.0.

Phenolic metabolic microorganisms, which are heterotrophic microorganisms, live by supplying organic matter from acidic to neutral soil. If the pH is neutralized to 7.4 to 7.0, phenolic metabolizing microorganisms can be converted to fiber, lignin, and cellulose. It creates humus soil by changing hemicellulose, protein, and minerals. Since organic waste is rich in the above-described substances, through anaerobic fermentation for 1 to 20 days, eco-friendly, highly functional artificial pit with a carbon content of 60% or less is generated by the beneficial metabolic activity of phenolic metabolizing microorganisms.

The fermentation process by lactic acid bacteria, which is a phenol-based metabolism active microorganism, acts to change the high molecular weight carbohydrates and proteins in the organic matter into low molecular form, providing food to the beneficial bacteria and synthetic bacteria. Under aerobic conditions, photosynthetic cyanobacteria and green algae In addition, it plays a role in proliferating nitrogen-fixing bacteria, photosynthetic bacteria, and yeast bacteria under anaerobic conditions, and is activated when the pH is 7.4 to 7.0. Since lactic acid is an organic acid that is beneficial to the roots, it suppresses harmful bacteria and dissolves salts, especially insoluble phosphoric acid, accumulated in the soil when excessive fertilization is dissolved, so that it is absorbed by the roots to make a healthy synthetic soil. In addition, since lactic acid fermentation only generates respiratory heat around 40 ℃, it is not decomposition that emit high energy, so only 1/20 of the energy consumed in aerobic high pyrolysis is sufficient.

In addition, the artificial pit of the present invention promotes activities such as Mycorrhiza, a phenol-based metabolizing microorganism active on the surface of the root hair of the soil, thereby increasing the resistance of salt in the soil and reducing the amount of fertilizer. It can be usefully used as a raw material such as a soil conditioner.

Mycorrhiza, which is active on the surface of the roots of plants, attaches to the roots and extends the mycelium in and out of the roots, absorbing water and nutrients like the roots of plants, and creating a protective film on the roots to reduce drought damage and prevent the invasion of harmful germs. It blocks, and you get the sap and some nutrients from the plant through the hyphae in the roots. In particular, phosphoric acid is difficult for plants to absorb due to phosphate fixation, but it is easily absorbed with the help of mycorrhizal roots, and helps to absorb copper, zinc, molybdenum, etc. well.

The artificial pit created in the present invention can be put into a sorting machine to sort and remove remaining vinyl or garbage that cannot be removed in the pretreatment process, and through this process, particles are even and the garbage is finally removed, thereby maximizing marketability. do.

As described above, the present invention significantly reduces operating costs by controlling odor by using an eco-friendly resource conversion system that does not use energy for organic waste such as food waste, and minimizing the amount of drinking water, and reduces organic waste to eco-friendly high-functional artificial pit ( Neo Peat) can be used to produce a clean natural environment, reducing carbon dioxide, preventing global warming, and improving soil.

Item Standard standard when using fertilizer Natural feet Artificial feet of the present invention pH - 5 ∼ 6.5 7.4 ∼ 7.0 Organic matter 25% or more 48 ∼ 78% Around 60% moisture 50% or less Around 40% 20 ∼ 40% salt Less than 1% Around 0.45% 0.27% or less Organic to nitrogen ratio 50 or less Around 34 20 ∼ 30

For reference, the artificial pit manufactured in the present invention (Neo Peat), unlike artificial soil, is a sound synthetic pit manufactured to play a similar role to such natural pollution-free pit (Peat). The components of this artificial pit (Neo Peat) are compared with the natural pit and shown in Table 1.

Synthetic artificial soils mostly require light weight, adsorption, ventilation, etc., and are manufactured similar to natural soil for the purpose of using materials for construction or civil works, lightweight soil for greening, pots and flower beds, etc. Since most of the silver has different purposes and does not require humus, it has a completely different function from the artificial pit (Neo Peat) manufactured in the present invention containing a large amount of organic matter.

Therefore, it will help to reduce the amount of natural peat used as a moisture control agent, odor remover, etc. in a livestock shed or sewage sludge treatment plant, and use artificial pit (Neo Peat) to reduce damage to nature and preserve it well.

In the detailed description of the present invention described above, it has been described with reference to preferred embodiments of the present invention, but those skilled in the art or those of ordinary skill in the relevant technical field, the spirit of the present invention described in the claims to be described later. And it will be appreciated that various modifications and changes can be made to the present invention within a range not departing from the technical field.
