The present invention relates to an organic-inorganic organic and organic compost for replenishing carbon sources, amino acids and inorganic elements including paper sludge, beer foil and steel slag powder, and more specifically, to manufacture paper sludge rich in carbon sources generated in the papermaking process and beer. Drying and solidifying the mixed composition containing the beer material rich in amino acids as the remaining nitrogen source, the steel slag powder and vermiculite powder rich in inorganic elements, and the organic material mixed with cornstalk powder or soybean powder and peat moss. It relates to an organic-inorganic and organic-compost compost containing paper sludge, beer foil, and steel slag powder to supplement carbon sources, amino acids, and inorganic elements by bulking or powdering.

The domestic paper industry continues to grow at a high level such that the consumption of paper per person exceeds about 1,200kg per year, and the paper manufacturing process in the paper industry uses 10 to 30 tons of paper per ton of paper products. The amount of sugar used per process is the second most common after the dyeing process.

The paper sludge generated due to the use of the process water is wastewater generated from water pollution prevention facilities such as dissociation, pulp and deinking processes in the papermaking process, and the amount is estimated to be around 1.6 million tons per year, but it is increasing every year.

These paper sludges are classified into pulp, paper, and wastewater treatment sludge, and are generally treated by methods such as landfill, marine discharge, and incineration, but direct reclamation of paper sludge is prohibited from July 2003 due to the revision of the Enforcement Regulations of the Waste Management Act. It was recycled by incineration or by mixing with a compound such as cement asphalt to adjust it to a certain moisture content or less, or landfilling or composting by biological methods.

In particular, for paper sludge, the government banned ocean dumping until February 2011, and announced the principle of land disposal through recycling, etc., and has banned ocean dumping from 2016. Accordingly, various recycling technologies for treating paper sludge on the ground have been tried.

Looking at the conventional techniques for recycling of the paper sludge, rice husks crushed with 10 to 100 mesh after drying to a moisture content of 5 to 10% in Korean Patent Registration No. 10-1530552 (date of registration June 16, 2015) 70 to 80 parts by weight of powder; and 20 to 30 parts by weight of paper sludge dehydrated to have a water content of 30 to 40%; A solid fuel is known, characterized in that it is prepared by mixing and then forming a moisture content of 20 to 25%.

In addition, a mixture preparation step of preparing a mixture by mixing paper sludge and coffee grounds in Korean Patent Registration No. 10-1876555 (date of registration July 3, 2018); A drying step of drying the mixture prepared in the mixture preparation step; And a molding step of compressing and molding the mixture dried in the drying step, wherein the mixture further includes wood flour, and the mixture is 12 to 100 parts by weight of the coffee grounds, based on 100 parts by weight of the paper sludge, 45 to 100 parts by weight of the wood flour is mixed, the calorific value of the molded product prepared in the forming step is 3,000 to 4,500 Kcal / kg, and in the mixture manufacturing step, the paper sludge is subjected to a pretreatment process to reduce metal components. It is to be used, so that the water content adjusted to 40 ~ 60% by weight through the dehydration process is used, in the mixture manufacturing step, the water content of the mixture of the paper sludge and coffee grounds is made of 30 to 70% by weight, , In the drying step, the water content of the mixture prepared in the mixture preparation step is to dry to 10 ~ 30% by weight, in the drying step, the horn A steam drying device is used for drying the mixture, and the steam drying device is formed in a vertical cylindrical structure, and receives a steam of 130 to 150 ° C generated by a boiler to dry the mixture using indirect heat, the chamber Consists of a steam trap for converting the steam used in drying to condensate and a condensate tank for storing condensate in the steam trap, the condensate stored in the condensate tank is made to be recycled as boiler water, the interior of the chamber is a drying section And a drying adjustment section, a screw feeder for quantitatively supplying the mixture into the chamber is installed in the drying section, and a plurality of turbine pins in which the mixture introduced into the chamber through the screw feeder is attached to the rotating shaft of the chamber. The centrifugal force is applied through the rotation of the film to adhere to the wall in a thin film form and applied to the chamber. With evaporation of moisture by indirect heat, drying progresses, mixing and drying are simultaneously performed through the space between the shorted turbine fins, and then the mixture reaching the uppermost layer is dropped and moved to the drying control section located at the bottom. In particular, a method of manufacturing solid fuel using paper sludge and coffee grounds as a main raw material is characterized in that drying proceeds in the same principle as the drying section through rotation of a plurality of cyclone pins attached to the rotating shaft of the drying adjustment section. .

In addition, the Korean Patent Publication No. 10-2018-0097193 (published on August 31, 2018) using iron salt and lime to coagulate and settle paper waste water to obtain paper sludge; Thermally decomposing the paper sludge in a carbon dioxide atmosphere; And adsorption and removal of arsenic using paper sludge, which comprises adsorbing arsenic using the magnetic biocar recovered by the thermal decomposition as an adsorbent.

However, the conventional paper sludge recycling techniques are for mixing solid fuel with various additional components to utilize the high calorific value of paper sludge, or for thermally decomposing paper slurry to recycle, making the manufacturing process complicated and additional components. There is a problem in economical efficiency due to the large amount of manufacturing and production costs due to the need for equipment produced in a dedicated facility, or it is impossible to recycle at a large scale due to the small recycling scale.

On the other hand, in the process of cultivating crops, chemical fertilizers and pesticides are used to supplement insufficient nutrients or to smoothly grow the crops.However, excessive use of chemical fertilizers and pesticides causes problems such as soil acidification and decay of soil and buffers the soil The ability is rapidly declining.

Therefore, in recent years, the necessity of using compost for the implementation of organic farming is gradually increasing. The effect of organic compost used in the process of cultivating crops is the effect of fertilizer components contained in compost and the corrosion effect created by decomposition of organic matter. Can be mentioned.

During composting, carbon (C), nitrogen (N), phosphoric acid (P), and potassium (K) are contained in a large amount of trace elements essential for crop growth. By preventing the damage of crops due to the lack of trace elements, it is possible to significantly improve the quality, as well as the healthy growth of crops, and the high yield.

Looking at typical conventional techniques for composting, preparing a powder composition by mixing mineral, zeolite, and photocatalyst in Korean Patent Registration No. 10-1605542 (registration date March 16, 2016); And fermenting by mixing the powder composition and a moisture regulator in livestock manure, wherein the livestock manure is discharged from livestock fed with the feed to which the powder composition is added, and the mineral is phosphorus with respect to 100 parts by weight of nitrogen. 80 to 90 parts by weight, 75 to 85 parts by weight of potassium, 0.4 to 0.7 parts by weight of calcium, 15 to 25 parts by weight of magnesium, 18 to 26 parts by weight of sulfur, 16 to 24 parts by weight of silicon, 0.8 to Boron 1.0 part by weight, manganese 0.2 to 0.5 parts by weight, iron 20 to 26 parts by weight, zinc 0.8 to 1.2 parts by weight, copper 0.02 to 0.03 parts by weight, molybdenum 0.01 to 0.02 parts by weight, aluminum 12 to 20 parts by weight A method for producing compost using livestock manure is known, characterized by containing parts and 0.08 to 0.12 parts by weight of trace element groups.

However, the conventional composting method has a problem in that it is difficult to completely remove various harmful bacteria contained in the manure itself, and there is a problem in that a large amount of odor occurs in the composting process. Various composts have been developed to prevent them from occurring.

On the other hand, a technology that utilizes beer foil as a raw material for compost that has no odor has been developed.Beer foil contains inorganic elements together with proteins containing amino acids, and has been mainly used as a feed material, but it is used as an organic fertilizer. Looking at the prior art, in Korean Patent Publication No. 10-2007-0015899 (published on February 6, 2007), yeast yeast digestion was performed using the yeast of bakbak which was discarded after the mainstream production process, followed by decomposition of yeast cell components. As an amino acid product, fertilizer is produced by reusing the yeast contained in the main film produced after the production of alcoholic beverages such as beer and sake, adjusting the solid content to 4-18%, and promoting self-extinguishing and preventing microbial contamination. Alcohol 1-9% (v / v) and Protease0.01-1% (w / v) were added to auto-extinguish at a temperature of 40-60 ° C for 4-96 hours, and the decomposition After completion, a supernatant is obtained by centrifugation, followed by filtration, and an amino acid fertilizer containing various useful substances prepared by adding KH2PO4 is known.

In addition, Korean Patent Registration No. 10-1579485 (Date of registration December 16, 2015) is a new microorganism Bacillus subtilis (EST) (KACC92077P) that is separated from beer sludge and consists of the nucleotide sequence represented by SEQ ID NO: 1. ) Strain 2 × 10 6 ~ 3 × 10 7 cfu / ml and, beer sludge 5 ~ 10 wt%, kelp extract 2 ~ 5 wt%, anhydrous grapes 2 ~ 4 wt%, soy flour 1 ~ 3 wt%, remaining agar Organic fertilizers are known, comprising a culture medium consisting of Ross in an amount of 10 to 20% by weight relative to the total weight of the organic fertilizer, which has a better crop growth promoting effect than the new microorganism alone.

However, the compost produced using the beer foil is fermented separately by using the yeast contained in the beer foil, or it is used by separating the microbial strains contained in the beer foil and culturing it for a long time, so that the beer foil is not used as it is, and a separate post-treatment is used. Since it is used after, there was a problem that it takes a lot of time and process to produce organic fertilizer.

Accordingly, the present inventors manufacture paper-making sludge and beer generated in a carbon-rich paper-making process and compost the mixed composition containing the remaining beer foil and steel slag powder rich in inorganic elements, thereby making it an eco-friendly organic / inorganic material for replenishing carbon sources, amino acids, and inorganic elements. Composite compost was developed and the present invention was completed.

In particular, since the paper sludge has a high pulp content and a low nitrogen content, the carbon to nitrogen ratio (C / N ratio) reaches 95.8% on average, so it can be used as a very good carbon source. 1] and [Table 2].

Physical composition moisture Combustible Ash sub Total 70.00 wt% 16.83% by weight 13.17% by weight 100% by weight

Chemical composition C H O N S Cl sub Total 8.91% by weight 1.26% by weight 5.64% by weight 0.77% by weight 0.17% by weight 0.08% by weight 16.83% by weight

The paper sludge is generated every year, and its treatment is emerging as a big problem.However, the paper sludge has been treated by incineration and landfill, but the government prohibits ocean dumping of paper sludge and implements the principle of land disposal through recycling. As disclosed, the present invention uses paper sludge for carbon source supplementation as part of an attempt to recycle paper sludge.

In particular, as the main raw material used in composting environmentally friendly organic and inorganic compost for replenishing carbon sources, amino acids and inorganic elements including paper sludge, beer foil and steel slag powder of the present invention, as shown in [Fig. 1], the waste process test criteria As a result of the test, it was analyzed that no harmful components were detected, indicating that it is suitable for compost use.

Meanwhile, beer foil is the most abundant by-product of beer brewing. This material consists of barley kernels that are obtained as solids after wort formation. Because beer foil is rich in sugar and protein, the main use of this product to date has been animal feed. However, because beer foil is high in dietary fiber and protein, for this very same reason, it is particularly useful as a potential source of bioactive, health-promoting compounds.

The beer foil consists of a seed-peel-skin layer covering the original barley grains. The starch content is generally low, and its composition mainly contains starch-free polysaccharides (NSP; hemicellulose and cellulose in the form of arabinoxysilane (AX)) and a significant amount of protein and fibrin which is lignin.

In particular, the protein content of beer foil is typically present at a level of about 30% per dry weight basis, the most abundant being hordein, gluterin, globulin and albumin. Essential amino acids are approximately 30% of the total protein content, lysine is the most abundant, while non-essential amino acids make up less than 70% of the total protein content, which is often an amino acid prone to deficiency in grain foods. It contains various inorganic components, and is particularly suitable as an organic / inorganic composite fertilizer raw material since it is rich in silicon, phosphorus, calcium, and magnesium.
