Description
본 발명은 음식물 쓰레기의 수분 처리방법에 관한 것으로서 이를 좀더 구체적으로 설명하자면 음식물 쓰레기를 최종적으로 처리(매립, 소각 등)하기 전에 음식물 쓰레기에 포함된 수분을 제거할 수 있는 방법을 제공하여 음식물 쓰레기를 최종적으로 처리할 때 환경(지하수, 토양, 대기 등)오염의 발생이 방지되도록 함에 그 목적이 있는 것이다.The present invention relates to a water treatment method of food waste, which will be described in more detail. The food waste may be removed by providing a method for removing water contained in the food waste before finally processing the food waste (landfill, incineration, etc.). Its purpose is to prevent the generation of environmental (groundwater, soil, air, etc.) pollution during the final treatment.
현재까지 알려진 바에 의하면 음식물 쓰레기는 그 수분 함유량이 약70% 정도이여서 이를 그대로 매립할 경우에는 음식물 쓰레기의 수분으로 인한 지하수는 물론 토양까지 오염시키게 되어 2005년부터는 수분이 포함된 음식물 쓰레기의 매립이 전면 금지되게 되고, 또 음식물 쓰레기를 소각할 경우에는 이 역시 수분으로 인하여 다이옥신등과 같은 대기오염물질을 발생시키게 된다.As far as is known, food waste has about 70% of its water content, so when it is landfilled, it contaminates groundwater and soil due to moisture of food waste. When the food waste is incinerated, this also causes air pollutants such as dioxins due to moisture.

이와 같은 점을 해결하기 위해 현재 음식물 쓰레기를 재활용하는 방안이 다각적으로 제시되고는 있으나, 이러한 방법들은 또 다른 환경오염을 유발 시킴은 물론 처리비용 역시 많이 들어 매우 비현실적이고 또한 시장성도 거의 없는 문제점등으로 인하여 현재에는 외면당하고 있는 실정이다.In order to solve this problem, there have been various proposals for recycling food waste, but these methods not only cause other environmental pollution but also have high disposal costs, resulting in very unrealistic and almost no marketability. Due to the current situation is neglected.
즉, 음식물 쓰레기를 사료화할 경우에는 시설비 및 연료비 등이 많이 들어 경제성이 없고, 이를 퇴비화할 경우에는 염류자해 및 초산염 발생 그리고 토양의 물리성 악화와 같은 문제점이 있다.In other words, when food waste is fed into a large amount of facility costs and fuel costs, there is no economic feasibility, and when composted there are problems such as salt harm and acetate salt generation and soil physical deterioration.

본 발명은 위와 같이 음식물 쓰레기를 처리함에 있어 나타나는 종래의 문제점을 해결하기 위함에 그 기술적인 과제를 두고 발명한 것으로서, 특히 음식물 쓰레기를 최종적(소각, 매립 등)으로 처리하기 전에 수분을 제거할 수 있도록 함으로써 음식물 쓰레기의 최종적 처리로 인한 토양, 지하수, 대기 등의 오염이 방지되도록 한 것이다..The present invention has been invented with the technical problem to solve the conventional problems appearing in the treatment of food waste as described above, in particular, it is possible to remove the moisture before the final disposal (incineration, landfill, etc.) of food waste. This prevents the contamination of soil, groundwater and air from the final disposal of food waste.
이하에서는 본 발명의 음식물 쓰레기의 수분 처리방법을 설명하기로 한다.Hereinafter, a method of treating water in food waste of the present invention will be described.
＜제 1공정＞<1st process>
농업부산물인(왕겨,옥수수줄기,짚등) 섬유소(Cellulose 입경5mm)500g과, 규산알미늄(Al2SiO3 )10g, 탄산칼슘(CaCO3 )5g, 산화칼슘(CaO) 2g, 산화규소(SiO2 ) 5g, 탄산나트륨(Na2CO3 )5g, 오산화바나듐(V2O5)2g, 산화티탄(TiO2 )2g으로 이루어지는 금속산화물과, 무정형탄소 미세분말(매탄,역전탄,무연탄등)700g과, 당밀100g을 일정형태의 반응기에 투입, 교반하면서 약100 - 120℃의 열을 가하여 알갱이 형태의 벌집형(hemeycomd)유기성분자체 세라믹스(이하 "분자체" 라 약칭함)를 만든다.Agricultural by-products (rice husk, corn stem, straw, etc.) 500g of fiber (Cellulose particle size 5mm), 10g of aluminum silicate (Al 2 SiO 3 ), 5g of calcium carbonate (CaCO 3 ), 2g of calcium oxide (CaO), silicon oxide (SiO 2 ) 5 g, sodium carbonate (Na 2 CO 3 ) 5 g, vanadium pentoxide (V 2 O 5 ) 2 g, metal oxide consisting of 2 g of titanium oxide (TiO 2 ), and amorphous carbon fine powder (methane, reverse carbon, anthracite, etc.) 700 g; 100 g of molasses is added to a reactor of a certain type, and heated to about 100-120 ° C. while stirring to form a granular honeycomb organic ceramics (hereinafter, abbreviated as “molecular body”).
＜제2공정＞<The second process>
상기 제1공정에서 제조된 일정량의 분자체에 수분을 포함한 음식물 쓰레기 분말(이하 "호정화액"이라 함)을 투입하여 약100℃ - 120℃열에서 약10 - 12분동안 교반시킬 때 음파(가청주파수)와 열풍을 공급한다.When the food waste powder containing water (hereinafter referred to as "stabilization liquid") was added to a predetermined amount of molecular sieve prepared in the first step and stirred for about 10-12 minutes at about 100-120 ℃ heat, Frequency) and hot air.
위에서 분자체에 투입되는 호정화(Dextrinization)액의 투입비율은 벌집형 세라믹스 분자체 전량 대비 약 20%비율로 한다.The ratio of dexterification liquid introduced into the molecular sieve is about 20% of the total amount of the honeycomb ceramic sieve.
이와 같이 된 본 발명은 제1공정에서 제조되는 분자체는 알갱이 형태이면서 벌집형이므로 흡장성 이온(ion)교환성이 강하게 되는데, 이는 호정화액의 수분을 흡장하는 반응이 뛰어나게 된다.In the present invention as described above, since the molecular sieve prepared in the first step is in the form of granules and honeycomb, the sorbent ion exchange ability is strong, which is excellent in the reaction of absorbing the water in the purified liquid.
즉, 분자체에 호정화액을 제2공정에서와 같이 적절한 비율로 투입한 후 일정시간 동안 교반하면 호정화액의 수분은 벌집형 분자체 표면의 모공을 통해 분자체 내로 흡수되게 되고, 수분이 제거된 호정화액의 유기성 부유물(음식물 쓰레기 분말과 수분내에 포함된 부유물)들은 분자체 표면에 흡착되게 된다.That is, when the purified liquid is added to the molecular sieve at an appropriate ratio as in the second step and stirred for a predetermined time, the moisture of the purified liquid is absorbed into the molecular sieve through the pores on the surface of the honeycomb molecular sieve, and the moisture is removed. Organic suspended solids (food waste powder and suspended solids in water) of the purified water are adsorbed onto the surface of the molecular sieve.
이때(음식물 쓰레기 분말과 분자체를 혼합 교반할 때)일정한 열을 가하게 되면 분자체 내로 흡수된 수분은 열에 의해 기화되어 비산하게 되고, 이로 인하여 분자체 표면에는 비산되는 수분 분자에 의해 모공이 발생하게 되며, 이 모공은 차기 수분이 흡수될 수 있게 한다.At this time (when mixing and stirring food waste powder and molecular sieves), if a certain amount of heat is applied, moisture absorbed into the molecular sieve is vaporized and scattered by heat, which causes pores to be generated by moisture molecules scattered on the surface of the molecular sieve. The pores allow the next moisture to be absorbed.
상기와 같은 반응(분자체 표면에 유기성 부유물의 흡착 반응과 분자체 내로의 수분 흡수와 기화 반응)을 반복하면 호정화액의 유기성 부유물과 그 수분을 처리할 수 있게되고, 이와 동시에 음파와 열풍을 공급하면 위 반응이 가속화 되어 반응시간이 단축되게 된다.By repeating the above reaction (adsorption reaction of organic suspended solids on the surface of the molecular sieve, absorption of water into the molecular sieve and vaporization reaction), the organic suspended solids of the purified liquid and its moisture can be treated, and at the same time, sound waves and hot air are supplied. This accelerates the reaction and shortens the reaction time.

여기서 호정화액과 분자체의 반응은 아래의 그림과 같이 이루어지게 되는데, 일반적으로 수분은 대체로 상온에서 이온결합체이며 이온성 상태에서 액체로 존재하여 100℃에서 비등하여 단일분자로 증발하게 된다.Here, the reaction between the purified liquid and the molecular sieve is made as shown in the figure below. In general, the water is generally an ionic bond at room temperature and is present as a liquid in the ionic state, and boils at 100 ° C. to evaporate into a single molecule.
한편 수분이 포함된 음식물 쓰레기를 호정화액으로 만들어 분자체와 반응시키는 이유는 각종 음식물 쓰레기에는 수분함량 및 함유성분등이 일정하지 않기 때문이다.On the other hand, food waste containing water is made into a purified liquid and reacted with molecular sieves because various food wastes have a constant moisture content and content.
따라서 본 발명은 상기한 바와 같이 제1공정에 의거하여 흡장성 벌집형 분자체를 만들고, 이를 제2공정에서 얻어진 호정화액과 혼합,교반시킴과 함께 호정화액의 유기성 부유물은 분자체 표면에 반복적으로 흡착되도록 하여 농축되게 하고, 호정화액의 수분은 분자체 내로 흡수되도록 한 후 기화 되도록 함으로써 수분이 제거되면서 화학변화된 음식물 쓰레기를 얻을 수 있으므로 이를 매립하더라도 토양 이나 지하수 등의 오염이 방지될 뿐만 아니라 위 수분이 제거된 음식물 쓰레기를 소각하더라도 다이옥신 등과 같은 유해물질은 제1공정에서 투입되는 금속산화물에 의해 그 발생이 억제되게되며, 한편 위 수분이 제거된 음식물 쓰레기를 경화제와 일정비율로 혼합,교반하면 유기성 고체연료로 제조할 수 있게되어 연간 다량으로 배출되는 음식물 쓰레기를 연료화 할 수 있게 되는 효과도 있는 것이다.Therefore, according to the present invention, the absorbent honeycomb molecular sieve is prepared according to the first step, and mixed with the stabilization solution obtained in the second step, and the organic suspended solids of the stabilization solution are repeatedly added to the surface of the molecular sieve. It is concentrated by adsorption, and the water of the purified water is absorbed into the molecular sieve, and then vaporized to obtain chemically changed food waste by removing water. Even if the removed food waste is incinerated, harmful substances such as dioxin are suppressed by the metal oxide introduced in the first step, and the organic matter is mixed and stirred at a predetermined ratio with the food waste from which the above water is removed. Food can be produced in solid fuel, which is emitted in large quantities annually. Effect which can be yeonryohwa group would in.
