Description
본 발명은 음식물쓰레기로부터 알코올을 만드는 방법에 관한 것으로서, 더욱 상세하게는 수거된 음식물쓰레기를 파쇄 및 이물질을 분리처리한 것을 탈수처리하여 탈수된 탈수케이크로부터 알코올을 만드는 방법에 관한 것이다.The present invention relates to a method for producing alcohol from food waste, and more particularly, to a method for producing alcohol from dehydrated dewatered cake by crushing collected food waste and separating and treating the separated food waste.
음식물쓰레기는 유기물농도가 높으면서 함수율이 높아 탈수처리 후 탈수 여액은 오염물질의 농도가 높아서 2012년 말까지는 대부분 해양투기를 함으로서 해역의 오염을 야기하는 문제점이 있었으며, 탈수케이크는 퇴비화를 하였으나 염분농도가 높아서 작물의 염해를 야기하는 문제가 있어서 양질의 퇴비를 생산할 수 없는 문제점이 있었다. 그래서 음식물쓰레기 탈수 여액을 혐기성 메테인발효, 하수병합처리를 시도하였으나, 음식물쓰레기 중에는 지방산 함량이 높아서 미생물의 집단(Colony)을 응집 및 표면의 코팅(Coating)현상을 야기시켜 처리효율을 떨어뜨리는 문제가 있어 적용할 수 없었으며, 그리고 음식물쓰레기를 쓰레기소각로 등에서 산업쓰레기와 함께 분무소각을 시도하였으나, 소각 시 음식물쓰레기에 함유된 염소성분과 유기물질이 반응하여 다이옥신(Dioxine)과 같은 2차 오염물질이 배출되는 문제점이 있었다. Food waste has a high water content with a high concentration of organic matter, and the dehydration filtrate after the dehydration treatment has a high concentration of contaminants. Therefore, there is a problem that the dehydration cake is composted by the end of 2012, There is a problem that it causes salting of the crop and there is a problem that the compost of good quality can not be produced. Therefore, it has been attempted to perform the fermentation of anaerobic methane fermentation and sewage in the food waste dehydration filtrate, but the food waste has a high fatty acid content, which causes coagulation of microorganisms and coating of the surface, And the food waste was tried to be incinerated together with the industrial waste in the incinerator of the garbage incinerator. However, when the incinerator is incinerated, the chlorine component contained in the food garbage reacts with the organic substance and the second contaminant such as dioxin There has been a problem of being discharged.
2013년부터 유기성 폐기물과 같은 오염물질을 국제협약에 의해서 해양투기가 금지되었기 때문에 음식물쓰레기와 같은 고농도 유기성 폐기물을 합리적으로 처리할 수 있는 방안이 강구되어야 하는 실정에 있다.Since 2013, international dumping of pollutants such as organic wastes has been banned by the International Convention, there is a need to find ways to rationalize treatment of high concentration organic wastes such as food wastes.
종래에는 탄수화물의 알코올발효는, 탄수화물을 누룩의 누룩곰팡이나 맥아(麥芽)를 이용하는 방법, 수산(蓚酸), 염산(鹽酸) 또는 황산(黃酸)으로 가수분해하는 방법, 아밀라아제(Amylase) 효소를 이용하는 방법과 같은 당화방법으로 당화한 다음, 사카로미세스속(Saccharomyces sp.) 효모나, 자이모모나스 모빌리스(Zymomonas mobilis) 혐기성 세균에 의해서 알코올발효를 하였으나, 상기 종래의 당화방법은 비용이 많이 드는 문제점이 있다.Conventionally, alcohol fermentation of carbohydrates can be carried out by a method in which a carbohydrate is hydrolyzed with koji fungus or malted sprouts of koji, oxalic acid, hydrochloric acid or sulfuric acid, amylase enzyme , And the fermentation was carried out by Saccharomyces sp. Yeast or Zymomonas mobilis anaerobic bacteria. However, the above conventional saccharification method is costly, and therefore, There is a lot of problems.
본 발명은 상기 종래 기술의 문제점을 해결하려는 기술로서, 음식물쓰레기를 탈수처리하여 탈수된 탈수케이크로부터 알코올을 만드는 방법을 제공하는데 그 목적이 있다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a method for producing alcohol from dehydrated dewatered cake by dehydrating food waste.

The alcohol fermentation liquid is supplied to the upper end and the lower end of the distillation tower 310 with a layer of packing or tray 311. The alcohol fermentation waste liquid in the lower part of the distillation tower 310 is supplied to the reboiler 313) to supply heat to the lower portion of the distillation tower 310 using steam so that the temperature of the lower portion of the distillation tower 310 is maintained at 90 ° C. The excess alcohol fermentation waste liquid is sent to the composting process or the methane fermentation process, The ethanol component contained in the alcohol fermentation liquid is evaporated and the ethanol vapor which has passed through the packing or tray 311 layer and is discharged to the upper part of the distillation tower 310 is supplied to the condenser 314, When the cooling water is supplied and cooled, ethanol and a part of the water are liquefied and sent to the distillate accumulator 315, and a part of the distillate containing ethanol is distilled from the distillation tower A distillation step of refluxing the upper part of the distillation column 310 to the upper part of the column 310,
The ethanol-containing distillate may be subjected to azeotropic distillation (azeotropic distillation) in which an azeotropic agent such as benzene, cyclohexane, or diethyl ether is introduced (introduced) , A solvent extraction distillation method (solvent extraction distillation method), a membrane separation method (membrane separation method), a synthesis method by a hydration reaction of ethylene (synthesis method), or a vapor phase adsorption method Removing ethanol from the food waste to produce high-purity ethanol, and producing high-purity ethanol.
