Description

음폐수 혐기성 에너지화 고도처리 설비{Food Waste Effluent Anaerobic Advanced Treatment System}Food Waste Effluent Anaerobic Advanced Treatment System

본 발명은 음식물 쓰레기의 처리 과정에서 발생되는 침출수(음폐수)를 고도 처리함과 동시에 바이오 가스를 생산하여 에너지화할 수 있는 설비에 관한 것이다.
The present invention relates to a facility capable of producing energy and producing biogas at the same time as advanced treatment of leachate (wastewater) generated during the treatment of food waste.

일반적으로 산업발달과 함께 소득증대와 소비성향의 변화 및 유통구조의 발달로 인하여 생활 폐기물은 급격히 증가되는 추세이다.In general, with the development of industry, household waste is rapidly increasing due to income growth, changes in consumption tendency, and development of distribution structure.

생활 폐기물의 처리방안으로 선택될 수 있는 것으로는 매립지를 확보하여 매립처리하는 방법, 소각하여 처리하는 소각방법, 재가공하여 새로운 자원으로 활용하는 방법 등이 있다.The disposal options for household wastes include landfills, landfills, incineration, and reprocessing as new resources.

매립처리 방법의 경우는 처리 후 매립지의 지질오염과 유해가스발생, 그리고 수질오염 등의 공중위생상 많은 문제점과 함께 매립지 확보를 위한 경제적 부담이 뒤따르는 문제점이 있었고, 소각처리 방법의 경우는 소각처리를 위한 경비의 부담과 소각시 대기오염이 발생되는 문제점이 있으며, 또 처리대상물인 폐기물의 종류에 제한을 받는 문제점이 있다.In the case of landfill treatment, there were many problems of public health such as geological pollution, harmful gas generation, and water pollution after disposal, followed by economic burden to secure landfill.In case of incineration treatment, incineration treatment There is a problem that the air pollution occurs when the burden of the expense and incineration, and there is a problem that is limited to the type of waste being treated.

재활용처리 방법의 경우는 최상의 처리방법에 해당되는 것으로 보여지나, 재활용으로 인한 효용성에 따라 재활용 가능 여부가 결정된다. 즉, 재활용을 위한 처리비용 문제에서 경제성 여부가 중요하고, 재활용처리 과정에서 이차적인 환경오염발생 여부가 중요하며, 재활용에 의한 최종제품의 품질 만족도에 대한 종합적인 분석을 통하여 재활용 처리 방법이 선택된다.Recycling treatment seems to be the best treatment method, but it is determined whether it can be recycled depending on its effectiveness. In other words, whether or not economic feasibility is important in the treatment cost for recycling, secondary environmental pollution is important during the recycling process, and the recycling treatment method is selected through a comprehensive analysis of the quality satisfaction of the final product by recycling. .

위와 같은 생활 폐기물에 대한 처리방법의 결정은 폐기물의 물성에 따라 선택될 수 있는 것이다.Determination of the treatment method for the above-mentioned municipal waste can be selected according to the physical properties of the waste.

특히, 일반 식생활에서 폐기물로 생성되는 음식물쓰레기는 대부분 유기질 폐기물로서, 매립처리시 수질오염 및 부패로 인한 악취발생 등의 심각한 환경오염원인이 되고 있는데, 음식물쓰레기는 소각처리가 부적당한 바 거의 매립처리 방법으로 처리하고 있었다.In particular, most of the food waste generated from waste in general diet is organic waste, which causes serious environmental pollution such as water pollution and odor caused by decay during landfill treatment. Food waste is inadequately disposed of as landfill. I was dealing with the method.

그러나, 매립처리 방법은 매립지 확보, 매립 후 주변의 토질변화, 유기물의 부패에 의한 가스발생으로 악취 및 그에 따른 대기오염과 수질오염 등 여러 형태의 비경제적, 비위생적, 비환경적 처리 방법으로 많은 문제점이 있었다.However, the landfill treatment method has many problems due to various types of uneconomical, unsanitary, and non-environmental treatment methods, such as securing landfills, changing soils after landfilling, gas generation due to decay of organic matter, and resulting air and water pollution. There was this.

따라서, 매립처리 방법의 문제점들을 해소하기 위하여 음식물쓰레기를 처리하여 재활용하는 방법이 제시된 바 있으나, 기존의 음식물쓰레기 처리장치는 반자동식으로 이루어져 있는데, 기존 음식물쓰레기 처리시에는 투입 전 수작업으로 이물질을 제거하고 처리과정에서 인위적으로 수분조절제 및 발효제를 혼합하여 생산하므로 첨가물의 경비가 많이 들고 인력비 또한 고가이기 때문에 경제성에서 떨어지고, 자원화 처리시 발생되는 악취를 처리하지 못하여 시설 주변의 주민들로부터 민원 발생의 근원이 되었다.Therefore, in order to solve the problems of the landfill treatment method has been proposed to recycle the food waste treatment, the existing food waste treatment device is made of a semi-automatic, when the existing food waste treatment to remove foreign substances by manual operation before input And artificially mixed with moisture control and fermentation in the process, the cost of additives is high and manpower costs are high, so it is economical, and it is not able to deal with the odor generated during the resource treatment process. It became.

이에 도1에 도시된 고농도 유기성 폐수의 처리방법(공개특허 제10-2010-0028413호)이 제시되었는데, 혐기성소화설비(20) 및 고도처리설비(30)에서 발생한 슬러지를 슬러지저장조(50)로 회수하고, 회수한 슬러지를 가용화장치(60)로 유입하여 가용화 한 후, 가용화한 슬러지를 혐기성소화설비(20)로 유입하여 미생물의 먹이 및 탄소원으로 활용함으로써 혐기성소화설비(20)의 메탄가스 발생량을 증진하여 폐수의 에너지화를 극대화하고, 한편으론 가용화한 슬러지를 외부 탄소원에 대체하여 고도처리설비(30)의 반응조에 선택적으로 공급함으로써 운전경비를 절감할 수 있도록 한 것을 특징으로 하고 있으나, 메탄가스의 수분 함유량이 높고, 이러한 과정에서 발생되는 악취를 제대로 처리할 수 없다는 단점이 있다.
Thus, the method for treating the high concentration organic wastewater shown in FIG. 1 (Publication Patent No. 10-2010-0028413) has been presented. The sludge generated in the anaerobic digestion facility 20 and the advanced treatment facility 30 is sludge storage tank 50. After recovering and solubilizing the recovered sludge into the solubilizer 60, the solubilized sludge is introduced into the anaerobic digestion facility 20 and used as a feed source and a carbon source of microorganisms, thereby generating methane gas in the anaerobic digestion facility 20. In order to maximize the energy efficiency of the wastewater, and on the other hand, it is possible to reduce the operating cost by selectively supplying the solubilized sludge to an external carbon source and selectively supplying it to the reactor of the advanced treatment facility 30, The water content of the gas is high, there is a disadvantage that can not properly handle the odor generated in this process.

본 발명은 음식 폐기물에서 발생되는 침출수(음폐수)를 처리하는 설비에 관한 것이다.The present invention relates to a facility for treating leachate (wastewater) generated from food waste.

음폐수집수조(110)는 음식 폐기물을 처리하는 과정에서 발생되는 음폐수를 집수하여 1차 저류하는 기능을 수행한다.The negative waste collection tank 110 collects negative waste water generated in the course of processing food waste and performs primary storage.

음폐수집수조(110)의 음폐수는 원수주입펌프에 의하여 배출되어 음폐수집진기를 통과하면서 협잡물이 제거된 후 산발효조(120)로 공급된다. The negative wastewater of the negative waste collection tank 110 is discharged by the raw water injection pump and is supplied to the acid fermentation tank 120 after the impurities are removed while passing through the negative waste collector.

산발효조(120)는 음폐수집수조(110)로부터 공급받은 음폐수를 산발효 미생물을 통하여 산발효 처리하는 기능을 수행한다.The acid fermentation tank 120 performs a function of acid fermentation of the negative waste water supplied from the negative waste collection tank 110 through an acid fermentation microorganism.
