Description

Technology Field

[0001] The present invention relates to a waste organic matter treatment device and a waste organic matter treatment system including the same, and more specifically, to a waste organic matter treatment device and a waste organic matter treatment system including the same that can treat waste organic matter including discarded food waste, sewage sludge, livestock manure, etc. using microorganisms. Background Technology

[0002] Due to recent industrial development and population growth, the amount of waste generated is increasing day by day. As waste causes environmental pollution and often results in the discarding of valuable resources contained within it, the efficient treatment and recovery of waste are considered crucial. Waste can be classified into organic and inorganic waste based on the characteristics of its constituent materials.

[0003] Organic waste can be defined as animal or plant waste derived from living organisms, with an organic waste content of 40% or more.

[0004] The types and sources of waste included in this category of organic waste are diverse. Food waste, sludge from sewage and wastewater treatment plants, waste from seafood processing plants, waste from agricultural and livestock processing plants, residues from food and paper mills, slaughterhouse waste, and livestock manure are examples of organic waste.

[0005] The increase in organic waste is emerging as the primary cause of environmental and water pollution. In particular, livestock manure discharged from farms is a solid-liquid substance generally produced during the metabolic processes of livestock, consisting of high-concentration organic matter with a BOD of approximately 20,000 to 30,000 ppm. Because this manure is composed of high concentrations of organic matter, discharging it without a separate treatment process leads to the pollution of rivers and lakes. Furthermore, it contains large amounts of nitrogen and phosphorus, causing eutrophication in water systems and rendering river water unusable for purposes such as drinking water and agricultural use.

[0006] High-concentration organic waste is difficult to treat due to its high moisture content and high concentration of emitted pollutants, and is generally disposed of through methods such as landfilling, incineration, and fermentation.

[0007] Meanwhile, the composting technology for sludge in wastewater treatment plants generally involves mixing and drying the sludge with sawdust, rice husks, etc., to adjust the moisture content within the sludge to around 60%, followed by a first fermentation process and a second fermentation process, after which foreign substances are removed, and the resulting product is used as compost or fertilizer.

[0008] However, a limitation of sewage sludge composting technology is that the processing capacity is very limited because the fermentation and decomposition of sewage sludge requires a long time and a large area.

[0009] In addition, sewage sludge is difficult to separate into water and solids, and there are concerns regarding odor generation and secondary pollution caused by the addition of chemicals during the wastewater treatment process. Furthermore, there are issues such as the risk of proliferation of pathogenic microorganisms and high operating costs for the treatment system.

[0010] Furthermore, food waste generated in households and restaurants contains a significant amount of moisture, leading to decomposition and the emission of severe odors during the waiting period for disposal. In particular, due to the characteristics of Korean food culture, food waste contains not only high moisture but also a considerably high salt content; if simply landfilled, this causes serious environmental pollution, including soil and groundwater contamination from leachate. Moreover, the severity of the disposal issue is very high because it requires vast landfill sites and is difficult to incinerate. Accordingly, as part of efficient food waste disposal methods, plans to recycle food waste into livestock feed or soil-improving fertilizer (compost) are being actively pursued; however, due to the high salt content, these methods are not very effective, and the actual processing volume remains minimal.

[0011] Therefore, as landfilling and incineration still account for a large proportion of the primary methods for food waste disposal, the risk of environmental pollution is increasing day by day. Furthermore, these conventional food waste disposal methods inevitably entail the generation of foul odors and inconvenience associated with collection, transportation, and storage, and also face the problem of requiring large-scale treatment facilities.

[0012] Meanwhile, as a solution to the problems of such typical food waste disposal methods, food dryers have recently appeared that allow for the heating and drying of food waste generated in households for disposal; however, these food dryers have not been an appropriate solution because they require a very long drying time and consume a significant amount of electricity.

[0013] Accordingly, recently, numerous food waste processors utilizing microorganisms have been proposed that conveniently decompose food waste generated in households and other sources into a liquid state using aerobic microorganisms, thereby allowing it to be discharged directly into the sewer without a separate collection process; examples of this include Korean registered patents No. 10-1463574 and No. 10-1351606. However, such processors generally suffer from a problem of reduced fermentation processing capacity because air is supplied to the upper side of the mixing tank, which prevents easy penetration into the waste organic matter located at the lower side of the mixing tank (or decomposition tank).

[0014] Meanwhile, when treating waste organic matter including the aforementioned livestock manure, sewage sludge, and food waste, gas is typically generated within the mixing tank and discharged to the outside. Before discharging the gas generated during waste organic matter treatment to the outside, it is heated or passed through deodorizing and filtration means to remove odors or harmful substances. Additionally, to improve waste organic matter treatment and energy efficiency, the gas is circulated to utilize the heat generated during the treatment.

[0015] There is a continuous demand for improved methods that can more efficiently utilize the heat of the gas generated and discharged from the mixing tank and enhance gas treatment efficiency. Prior art literature
