Description
본 발명은 폐기물 매립에 관한 것으로서, 보다 상세하게는 폐기물을 매립처리 시 폐기물을 파쇄와 대상 폐기물의 미생물 분해 속도와 분해과정을 조절할 수있는 약품과 접종 균주의 투입, 그 후 압축한 후 합성수지 필름으로 감싸는 포장공정을 추가 한 매립 방법에 관한 것이다.The present invention relates to waste landfill, and more specifically, to waste and landfill treatment, the wastes are shredded and the chemicals and inoculation strains can be controlled to control the microbial decomposition rate and decomposition process of the target waste, and then compressed into a synthetic resin film. It is about a landfill method which added the wrapping process to wrap.
일반적으로, 매립 작업에는 폐기물의 겉보기 비중을 크게 하여 매립용적을 줄이기 위해, 폐기물을 매립장에 펼친 후 매립용 불도져 등 매립 중장비가 매립대상 폐기물의 상부를 왕복 주행하여 그 자중을 이용한 다짐 작업을 실시 후 양토로 복토(30- 100Cm정도)하며, 근래 일부 매립장은 매립지의 수명을 늘리기 위해 매립물의 크기를 축소하기 위하여 파쇄기를 이용하여 파쇄 처리하여 매립물질을 균일하게 하거나 별도의 압축기를 설치하여 폐기물을 압축하여 결속하거나 하는 기계적 장치를 이용하는 공법들이 일부 또는 전부 사용하여 매립하기도 한다.In general, in order to reduce the landfill volume by increasing the apparent proportion of waste, the landfill heavy equipment such as bulldozers for landfills reciprocate the upper part of the landfill waste and compaction using its own weight. It is covered with loam (about 30-100cm), and recently some landfills are shredded using shredders to reduce the size of landfills in order to increase the life of landfills. Some methods that use mechanical devices to bind or bond together may be partially or completely buried.
이러한 매립 방법은 폐기물이 일단 대기 중에 노출되므로 서 악취와 폐기물의 날림(비산)이 발생하며, 유해 동물인 조수(까치나 까마귀)나 설치(쥐 등)류 그리고 유해 곤충(파리, 바퀴벌레 등)등의 접근이나 서식으로 매우 위생상으로 불량한 지역을 형성하여 인근 주민의 집단민원의 표적이 되고 있다. 이를 경감하기 위해 일일 작업이 완료되면, 반드시 양토로 중간복토(20-40Cm 정도)를 실시하여 폐기물이 대기 중으로 노출되는 것을 막고 있으나 공정의 특성상 작업 중에 대기 중에 폐기물이 노출되는 것은 근본적으로 막지는 못하는 문제점과 매립되는 폐기물이 매립이 이루어 저 미생물에 의해 분해작용의 진행 분해작용은 매립 당시 폐기물의 함수량, C/N비, 입경 등으로 분해 조건이 결정되어 매립자의 의도(침출수의 오염농도 낮춤, 메탄 발생량의 증가, 신속한 매립물의 안정화 등) 조절하기는 곤란한 문제점이 발생한다.This method of landfilling causes odors and flying (spraying) of wastes once they are exposed to the atmosphere, and harmful animals such as tides (crows and crows), rodents (rats, etc.) and harmful insects (flies, cockroaches, etc.) It is a very hygienic poor area due to the access and habitation of the community, making it a target for group complaints of nearby residents. In order to alleviate this, when daily work is completed, it is necessary to apply intermediate covering (about 20-40cm) with loam to prevent the waste from being exposed to the atmosphere, but due to the nature of the process, the exposure of the waste to the atmosphere during the operation is not fundamentally prevented. Problem and progress of decomposition process by low microorganism due to landfilled wastes The decomposition process is determined by the water content, C / N ratio, particle size, etc. of the waste at the time of landfill, and the intention of the landfiller (lower concentration of leachate, methane Increasing the amount of generation, rapid stabilization of the landfill, etc.) is difficult to control.
본 발명은 상기와 같은 문제점을 매립대상을 합성수지 필름으로 감싸는 공정을 추가하여 매립 시 폐기물의 비산(날림), 조수나 설치(쥐 등)류 그리고 유해 곤충 등의 접근을 차단하고, 중간복토를 생략 할 수 있으며, 대상 폐기물의 미생물 분해 속도와 분해과정을 조절할 수 있는 약품과 접종 균주의 투입 단계를 통하여 매립장 관리자의 의도로 침출수의 오염농도 낮추거나, 메탄가스 발생량의 증가 및 발생 시기의 조절, 신속한 매립물의 안정화, 또는 메탄가스를 포집 하지 않을 경우 메탄 발생량을 억제하는(메탄가스는 대기로 배출 시 온난 가스로 작용됨) 매립장 운전에 매우 효과적이며, 폐기물의 매립처리 시 차수시설이나 저류시설 등이 완전치 않거나 기타 여러 가지 사정에 의해 차수 시설이나 저류시설 등이 설치되지 않은 매립장서 매립 할 경우나 매립장 기반 시설이 완비된 매립장도 보다 환경에 친화적인 매립에 활용할 수 있다.The present invention adds a process for wrapping the landfill object with a synthetic resin film as described above to block the scattering (flying) of the waste during landfilling, tide or installation (rats, etc.) and access to harmful insects, eliminating intermediate covering It is possible to reduce the concentration of leachate, control the increase and the time of occurrence of methane gas, and promptly control the landfill manager's intention through the step of inputting drugs and inoculation strains that can control the microbial decomposition rate and decomposition process of the target waste. It is very effective for landfill stabilization of landfill, or to control methane generation when methane is not collected (methane gas acts as a warm gas when it is discharged to the atmosphere). When landfills do not have complete facilities or storage facilities due to incomplete or other circumstances. I can also take advantage of the more environmentally friendly buried in a landfill equipped landfill infrastructure.

The number of times the packaging material is wound depends on the size of the compressed waste, the uniformity of the crushing, the strength (thickness) of the packaging material, and the landfill conditions, but it is about 2 to 5 times.
여기서 매립물질의 분해 메카니즘을 살펴보면,Here, look at the decomposition mechanism of the landfill material,
먼저 1단계 분해과정 : 일단 매립물의 빈 공간 부근에 함유 한 공기 층 내의 산소에 의해 호기성 분해가 진행되며, 유기물의 가수 분해에 의해 유기물이 구조적으로 붕괴되는 현상이 생기며 가스 성분은 질소와 산소의 농도는 대기 중의 농도 79%, 21%에서 점점 감소되면서 탄산가스의 농도가 서서히 증가한다 소요 기간은 온도, 함수비, 입경 조건에 따라 다르나 대략 1주에서 4주정도 이다.First, one-step decomposition process: Once the aerobic decomposition is progressed by oxygen in the air layer contained near the empty space of the landfill, the organic matter is structurally collapsed by the hydrolysis of the organic matter. The concentration of carbon dioxide gas is gradually increased at the atmospheric concentrations of 79% and 21%. The duration is about 1 to 4 weeks depending on the temperature, water content, and particle size conditions.
2단계 분해과정 : 협기성 분해가 시작되는 과정으로 탄수화물은 분해균에 의해 알콜류, 지방산 등으로, 지방은 지방 분해균에 의해 지방산과 글리세린을 거쳐 지방산과 알콜류로 단백질은 단백질 가수 분해균에 의해 아미노산과 지방산으로 1차 분해된다. 이때 적용하는 각각의 균은 특별한 균이라 보다는 자연계에 널리 분포 되여 있는 통성협기성균류과 임의협기성균류가 포함된다. 이 단계에서는 산소는 고갈되며 질소는 약간 남아 있으며 수소가 발생하기 시작된다. 협기성 작용으로 유화수소와 암모니아도 발생하며 유기산의 농도가 증가에 의해 침출수의 PH가 감소한다. 소요기간은 대략 4-10주 정도이다.Two-stage decomposition process: Anaerobic decomposition begins, carbohydrates are decomposed bacteria, alcohols, fatty acids, etc., fats are decomposed bacteria, fatty acids and glycerin, fatty acids and alcohols, proteins are proteolytic amino acids. It is first broken down into fatty acids. At this time, each of the bacteria to be applied is not a special bacteria but includes a wide range of coarse anaerobic fungi and random anaerobic fungi. At this stage, oxygen is depleted, nitrogen remains slightly, and hydrogen begins to develop. The aerobic action also produces hydrogen emulsification and ammonia, and the pH of the leachate is reduced by increasing the concentration of organic acids. The lead time is approximately 4-10 weeks.
3단계 분해과정 : 2단계의 혐기성분해가 가속화되면서 유기산의 농도가 최고점에 도달되며 이산화탄소의 농도는 최고에 이른 후 메탄균에 의해 유기산이 분해되므로 서 메탄 가스의 발생이 시작되므로 감소하기 시작하며 침출수의 각종 오염물질은 최고점을 지나 서서히 감소한다. 여기서 유기산의 농도가 많아지면 PH가 너무 저하되면 메탄균의 활동조건을 억제하는 작용이 나타나며, 이 경우 유기산의 농도는 2000mg/L에서 PH가 6 미만에 도달되면 메탄 발생량은 급격히 감소된다.Three-stage decomposition process: As the anaerobic decomposition of two stages accelerates, the concentration of organic acid reaches its highest point, and the concentration of carbon dioxide reaches its highest, and methane gas starts to decrease as organic acid is decomposed by methane bacteria. The various pollutants in the soil gradually decrease past their peaks. If the concentration of the organic acid increases, too much PH appears to inhibit the action conditions of the methane bacteria, in this case, the concentration of the organic acid is rapidly reduced when the pH reaches less than 6 at 2000mg / L.
메탄균은 혐기성박테리아로 유기산과 알콜을 에너지 또는 탄소원으로 사용하면서 최종적으로 메탄과 이산화탄소 그리고 가타 물질을 생산하는 균으로 균류에 따라 작용 물질이 다르다Methane is an anaerobic bacterium that uses organic acids and alcohols as energy or carbon sources, and finally produces methane, carbon dioxide, and other substances.
침출수는 유기산의 작용으로 PH가 5 이하로 감소되며 유기산이 분해되면서 BOD, COD의 유기물 함량이 높아지며 낮은 PH에 의해 폐기물 내에 함유한 중금속과 같은 무기물질들의 농도가 증가된다. 소요기간은 4-10주이다.Leachate has a pH of 5 or less due to the action of organic acids, and the organic acid is decomposed to increase the organic matter content of BOD and COD, and the concentration of inorganic substances such as heavy metals contained in the waste is increased by low pH. The lead time is 4-10 weeks.
제 4단계 분해 과정 : 2단계와 3단계에서 생성된 유기산과 수소가 상기에서 표시한 메탄균류에 의해 메탄가스와 이산화탄소로 분해되는 단계로 매립지 내부 PH는 6 정도에서 8 정도의 중성으로 상승하며 침출수의 유기물질 농도도 감소한다. 이 단계의 지속기간은 매립물질의 성상과 량에 따라 다르나 최고 수년이 걸릴 수도 있다.4th stage decomposition process: organic acid and hydrogen generated in 2nd and 3rd stages are decomposed into methane gas and carbon dioxide by the methane fungus indicated above. The concentration of organic matter in the water is also reduced. The duration of this phase depends on the nature and quantity of the landfill material, but may take up to several years.
제 5단계 안정화 단계 : 4단계를 거처 유기물이 메탄과 이산화탄소로 전환되면 배출량은 급격히 감소되는 단계이며 소량의 질소와 산소가 존재하며 침출수 내의 유기물질도 낮은 수치를 보인다.5th stage of stabilization: When organic matter is converted to methane and carbon dioxide through 4th stage, emissions are reduced rapidly. There is a small amount of nitrogen and oxygen and organic matter in leachate is low.

위에서 고찰하여 본 바와 같이 매립 시에 많은 균주와 반응 물질이 참여하고 있음을 확인하였다As discussed above, it was confirmed that many strains and reactants participated in landfilling.
합성수지로 포장 되여 하나의 블록으로 형성된 폐기물 덩어리는 위에서 본 바 같은 독립된 하나의 혐기성 반응기로서 작용하여 가수분해 단계, 산형성 단계, 메탄분해단계, 안정화 단계를 거치게 된다.The waste mass packed into a resin and formed into one block acts as a separate anaerobic reactor as seen above, undergoing a hydrolysis step, an acid formation step, a methane decomposition step and a stabilization step.
본 발명의 또 하나는, 블록으로 형성된 폐기물의 덩어리에서 진행하는 각각의 분해작용을 조절하기 위해 먼저 반응에 참여하는 균주를 접종투입하고, 반응 대사물 인 유기산으로 인해 PH가 너무 하강하여 반응을 저하시키는 것을 막기 위해 폐기물의 성상을 고려하여 적당량의 알칼리 약품(예를 들면 칼슘 등) 투입하거나, 메탄을 회수치 않은 매립장의 경우엔 억제작용을 하는 이온을 충분히 투입하는( 이 경우 Mg++이온을 투입하기 위해 MgOH가 경제적으로 유리한 것임) 방법이다.In another aspect of the present invention, in order to control each decomposition proceeding in a block of waste formed into blocks, first inoculate the strain participating in the reaction, and the pH is too low due to the organic acid, the reaction metabolite, to lower the reaction. In order to prevent this from happening, an appropriate amount of alkali chemicals (e.g., calcium) is added in consideration of the properties of the waste, or in the case of a landfill where methane is not recovered, a sufficient amount of inhibitory ions are introduced (in this case, Mg ++ ions). MgOH is an economically advantageous method for dosing).
반응조절제는 알칼리 제재가 사용되며, 균주의 접종은 부식퇴비, 협기성소화조의 폐액이나 탈수 케익 등을 이용하거나 아니면 앞에서 본 메탄균류을 배양해서 분말이나 액상으로 제작하여 살포한다.Alkali preparations are used as reaction regulators, and inoculation of strains is carried out by using a corrosive compost, waste liquid from aerobic digestion tanks or dehydration cake, or by cultivating the methane fungus seen in the form of powder or liquid and spraying.
배양균의 배양은 폐기물에 함유된 유기물의 성상에 따라 적절히 균주의 배합비를 결정한다.Cultivation of the culture is appropriately determined the blending ratio of the strain according to the properties of the organic matter contained in the waste.
본 발명의 바람직 한 실시 예를 첨부한 도면에 의거 설명하면 다음과 같다.Referring to the accompanying drawings, preferred embodiments of the present invention are as follows.
도 1은 폐기물처리 흐름도를 도시한 것으로 기존의 일반적인 처리공정 즉 폐기물파쇄기(2)의 파쇄 단계, 여기서 파쇄의 파쇄기 구동력(회전 칼날의 회전 시 혼합 효과가 있음)을 이용하여 반응조절제(2-1)과 접종 균주 (2-2)을 투입 혼합하는 단계, 폐기물압축기(3)의 폐기물의 압축, 성형, 결속의 단계를 거쳐 폐기물은 합성수지 필름(4-1)으로 폐기물포장기(4)에서 포장되여 매립지에 매립되는 단계를 거치게 된다.1 is a flow chart illustrating a waste treatment flow, which is a conventional general treatment process, that is, a crushing step of a waste crusher 2, where a crusher driving force (the effect of mixing when rotating a rotary blade) is used to control a reaction regulator (2-1). ) And the inoculation strain (2-2) is added and mixed, the compression, molding, and binding of the waste of the waste compressor (3), the waste is packaged in the waste packer (4) with a synthetic film (4-1) The landfill is to be landfilled.
이상에서와 같이 본 발명에 의하면 1차로 매립대상을 합성수지 필름으로 포장하므로 매립 시 폐기물의 날림(비산) 조수나 설치(쥐 등)류 그리고 유해 곤충 등의 접근을 차단하고, 중간복토를 생략 할 수 있으며, 대상 폐기물의 미생물 분해 속도와 분해과정을 조절할 수 있는 약품과 접종 균주의 투입 단계를 통하여 매립장 관리자의 의도대로 침출수의 오염농도 낮추거나, 메탄가스 발생량의 증가 및 발생 시기의 조절, 신속한 매립물의 안정화, 또는 메탄가스를 포집하지 않을 경우 메탄 발생량을 억제하는(메탄가스는 대기로 배출 시 온난가스로 작용됨) 매립장 운전에 매우 효과적이며, 폐기물의 매립처리 시 차수시설이나 저류시설 등이 완전치 않거나 기타 여러 가지 사정에 의해 차수 시설이나 저류시설 등이 설치되지 않은 매립장서 매립 할 경우나 매립장 기반 시설이 완비된 매립장도 보다 환경에 친화적인 매립에 활용할 수 있다.As described above, according to the present invention, the landfill object is first packaged with a synthetic resin film, thereby preventing the access of waste (flying) tides, rodents (rats, etc.), harmful insects, and the like during the landfill, and eliminating intermediate soil. Through the step of injecting drugs and inoculation strains that can control the microbial decomposition rate and decomposition process of the target waste, the landfill manager's intention to reduce the pollution concentration of leachate, increase the amount of methane gas generation and control the timing of occurrence, and prompt landfill It is very effective for the operation of landfill where stabilization or methane generation is not collected (methane gas acts as a warm gas when discharged to the atmosphere). In case of landfill where landfill or storage facility is not installed due to various reasons or Landfill sites equipped with landfill infrastructure can also be used for more environmentally friendly landfills.
