Description
본 발명은 매립을 위한 산업폐기물의 고형체로서, 이를 보다 상세히 설명하면 소각회, 알루미늄광재 등의 산업폐기물을 땅속에 매립할 시 고형화시켜서 매립되도록 하여 매립장에 침출수처리장치 등이 필요 없으므로 설비가 간단하게 이루어지며, 매립 후 친환경적이면서 지반을 강화시킬 수 있도록 한 산업폐기물로 이루어진 매립용 고형체에 관한 것이다.
The present invention is a solid body of industrial wastes for landfill. More specifically, when industrial wastes such as incinerators and aluminum slag are buried in the ground, the wastewater treatment apparatus is not required in the landfill And an industrial waste that is eco-friendly and capable of strengthening the ground after landfilling.
일반적으로 산업폐기물로는 소각회 중 비산재(fly ash; 이후 '소각회'로 통칭함), 분진, 오니(슬러지), 알루미늄광재 등의 각종 슬래그, 폐주물사, 폐석분 및 폐유 등 다양하며, 우리나라에서 이러한 산업폐기물은 주로 매립이 약 80%, 재생활용이 약 15% 등으로 처리되고 있으며, 나머지는 소각처리하거나 기타 그 종류에 따라서 미생물에 의한 처리, 활성탄흡착, 화학적 침전, 증류, 오존처리, 고화처리 등의 다양한 방법에 의해서 처리되고 있는 실정이다.In general, industrial wastes include various kinds of slags such as fly ash (hereinafter collectively referred to as "incinerator"), dust, sludge, aluminum slag, wastes, wastes, and waste oil. These industrial wastes are mainly treated with about 80% of landfill and 15% of recycled use, and the remainder are treated by microbial treatment, activated carbon adsorption, chemical precipitation, distillation, ozone treatment, And the like.
상기 산업폐기물의 처리 중 가장 많은 경우에 해당되는 매립방법을 살펴보면 산업폐기물을 종류별로 분말화시켜서 혼합한 후 가연성 자루에 채운 후 매립지인 지정된 산업폐기물매립장으로 운반한 다음, 원칙적으로는 매립지에 매립 후 가연성 자루는 모두 수거해야 하지만, 이러한 가연성 자루는 수거한 다음 최대 지름 15cm 이하의 크기로 절단, 파쇄한 후 용융시켜서 매립처리를 해야 하므로 추가적인 처리공정과 처리비용이 소요되므로 가연성 자루를 산업폐기물이 내입된 상태에서 함께 매립하는 행위가 암암리에 빈번하게 자행되고 있었으며, 이로 인하여 토질오염 등의 환경이 파괴되고 있었으며, 가연성 자루를 일일이 수거하여 분말화된 산업폐기물만 매립하더라도 매립 시 다량의 분진이 발생하여 주변공기가 오염되며, 우수(雨水) 등이 스며들게 되면 매립된 분말폐기물에서 침출수가 대량으로 발생되어 주변토양이 오염되므로 매립장의 설치반대와 설치 후 민원제기의 요인이 되었으며, 이를 방지코자 지정된 매립장에는 침출수를 수거하기 위한 침출수처리장치를 설비토록 법제화되어 있으므로 매립지를 구현하는데 설비비가 많이 들었으며, 침출수의 수거 후 이를 처리하기 위한 유지 및 보수비용이 다대하게 소요되는 등 환경파괴 외에도 경제적으로 그 효율성이 극히 낮았던 것이다.As for the landfill method corresponding to the most cases of the above-mentioned industrial wastes, the industrial wastes are pulverized according to their types, mixed and filled into a combustible bag, and then transported to a designated industrial waste landfill, which is then landfilled. In principle, However, since such flammable bags must be collected and dismantled after being cut and crushed to a size of 15 cm or less in maximum diameter, it is necessary to carry out the landfilling treatment. Therefore, additional processing steps and processing costs are required, The landfill was buried together with the landfill, and the environment such as soil pollution was destroyed. Even if only combustible bags were collected and only powdered industrial waste was buried, a large amount of dust was generated at the time of landfilling The surrounding air is polluted, and rainwater In case of landfill, waste water is generated in large quantities and polluted the surrounding soil. Therefore, it is a cause of complaints against installation of landfill site and complaints after installation. In order to prevent this, the landfill designated to prevent leachate is legislated to install leachate treatment equipment And the cost of maintaining and repairing the leachate after the collection of the leachate was enormous. In addition to environmental destruction, the efficiency of the leachate was economically very low.
상기 분말화된 산업폐기물의 매립을 일부라도 줄이고자 산업폐기물을 재활용토록 한 기술이 근자에 들어서 다수 개발되고 있는바, 산업폐기물을 이용한 재활용방안으로는 대한민국 공개특허 2000년 63243호(2000년 11월 6일자 공개)에서 타일을 제조하거나, 공개특허 2000년 72441호(2000년 12월 5일자 공개)에서 아스콘채움재를 제조하거나, 공개특허 2003년 46064호(2003년 6월 12일자 공개)에서 건축자재, 벽돌, 보도블록, 기와 및 텍스 등을 제조하는 기술이 게재되어 있었으나, 이러한 재활용의 경우 전체 산업폐기물의 일부에 지나지 않으며, 재활용하기 위해서 다수의 공정이 소요되면서 재활용 비용도 높아서 상기에서와 같이 전체 산업폐기물 양의 15% 정도에도 못 미치는 등 다수의 문제점을 가지고 있었던 것이다.
In recent years, a number of technologies have been developed to recycle industrial waste in order to partially reduce the burial of the pulverized industrial waste. As a recycling method using industrial waste, Korean Patent Publication No. 63243 (Japanese Unexamined Patent Application Publication No. 2000-72441, published on Dec. 5, 2000), or a method of manufacturing a tile in a construction material (Japanese Patent Laid-Open Publication No. 2003-46064 , Bricks, sidewalk blocks, tiles, and texts. However, such recycling is only a part of the total industrial waste, and since a large number of processes are required for recycling, the recycling cost is also high, And less than 15% of the amount of industrial waste.
본 발명에서는 상기한 종래 기술의 제반 문제점들을 해결코자 새로운 기술을 창안한 것으로서, 본 발명은 각종 폐기물을 소각할 때 발생되어 연도에서 집진기에 의해 포집된 분진을 포함한 소각회와 알루미늄 용해 시 발생되는 분진류인 알루미늄광재와 폐주물사 및 폐석분에 경화재인 시멘트를 혼합하여 시멘트와 물의 수화반응(水和反應)에 의해서 성형 후 양생시켜서 고형화시킨 다음 매립토록 하여 매립 후 침출수가 발생되지 않으므로 매립지에 침출수처리장치가 필요 없어서 설비비나 유지 및 보수비용이 극감하게 되며, 침출수에 의한 토질오염을 방지하여 환경파괴를 예방하므로 매립장의 설치반대 및 민원제기를 일소할 수 있으며, 이에 더불어 시멘트와 함께 미세분말의 점토 또는 황토를 혼합하여 산업폐기물을 고형화시키므로 보다 환경 친화적이면서도 응집력을 향상시킬 수 있는 매립을 위한 산업폐기물의 고형체를 제공함에 해결하고자 하는 과제를 두고 본 발명을 완성한 것이다.

상기 덩어리는 다양한 크기와 모양을 갖도록 할 수 있으나, 그 크기를 보통 적벽돌 이나 콘크리트벽돌 등의 표준형 벽돌의 절반 정도의 크기인 가로 90~110mm, 세로 90~100mm, 폭 57~67mm로 성형함이 바람직하며, 직육면체 외에도 구형이나 원통형 또는 각종 다면체로 성형할 수도 있다.The size of the block can be variously sized and shaped, but its size is usually about 90 to 110 mm, 90 to 100 mm, and 57 to 67 mm wide, which is about half the size of standard bricks such as red bricks and concrete bricks. And may be formed into a spherical shape, a cylindrical shape, or various polyhedrons in addition to a rectangular parallelepiped.
그리고 본 발명에서 상기 혼합폐기물에 배합되는 경화재인 시멘트로는 널리 알려진 포틀랜드 시멘트를 주로 사용하며, 시멘트 80~90중량%에 0.002~0.005mm의 미세한 분말로 이루어진 점토 10~20중량% 또는 황토 10~20중량%를 혼합하여 경화재로 사용하여 석회질의 시멘트로만 이루어질 때보다 친환경적이면서 응집력을 향상시킬 수 있도록 한다.In the present invention, cement as a curing material to be blended in the mixed waste is mainly used Portland cement is widely used, and 10 to 20% by weight of clay made of fine powder of 0.002 to 0.005 mm in 80 to 90% by weight of cement, 20% by weight of a cementitious material is used as a curing material so as to be more environmentally friendly and improve cohesion than when it is made of only calcareous cement.
또한 상기 혼합폐기물에 중량비 2:1:1로 배합되는 경화재인 시멘트와 시멘트의 수화반응을 위한 물을 산업폐기물 중 하수 슬러지인 오니를 중량비로 2:2:1의 비율에 맞추어 혼합하여 혼합폐기물에 배합할 시에도 응집력을 향상시키면서 점토나 황토에 비하여 버려지던 오니를 사용하므로 보다 많은 산업폐기물을 손쉽게 처리할 수 있는 것이다.In addition, water for hydration reaction of cement and cement, which are mixed with the mixed waste at a weight ratio of 2: 1: 1, is mixed with sewage sludge of industrial waste at a weight ratio of 2: 2: 1, Even when blended, the sludge that has been dumped compared to clay or loess is used while improving cohesion, so that more industrial wastes can be easily handled.
상기 산업폐기물 중 소각회는 각종 폐기물을 소각할 때 발생되는 소각회(燒却灰)는 불연(不然)성분과 미처 타지 못한 일부 가연(可燃)성분이 소각로 안의 화격자 아래 놓인 잔류물 호퍼로 떨어진 바닥재(bottom ash)와 소각로에서 발생하여 건식 스크러버와 여과식 집진장치에서 걸러진 재로서 집진재 또는 플라이애시라고도 일컫는 비산재(fly ash)로 나뉘며, 본 발명에서의 소각회는 상술한 바와 같이 플라이애시로 불리는 비산재(飛散灰)를 사용하며, 이는 연도에서 집진기에 의해 포집되어 분진이 포함된 것이다.Among the industrial wastes, incineration ash is generated when incinerating various wastes, and incineration ash is composed of an unburned component and a part of combustible components which are not buried in the incinerator, (bottom ash) and a fly ash which is generated in the incinerator and is filtered by a dry scrubber and a filtration type dust collector and is referred to as a dust collecting material or fly ash. The incinerator in the present invention is a fly ash Fly ash is used, which is collected by the dust collector in the year and contains dust.
상기 본 발명에서 소각회로 사용되는 비산재에는 납·카드뮴·아연 등의 중금속과 다이옥신이 들어 있으며, 비산재는 마이크로 또는 그 이하 크기의 입자상물질이므로 조심해서 다루지 않으면 날아가 작업자와 주변 환경에 해를 끼치게 되며, 전기집진기와 백필터(bag filter)는 보통 99% 이상의 입자상물질 제거효율을 가지므로 진공컨베이어를 이용하여 오염방지시설로부터 제거한 뒤 밀폐용기를 이용하여 수송해야 하며, 발생량은 여러 가지 조건에 따라 다르지만 비산재는 쓰레기의 물리화학적 성질과 처리기술에 따라 다르며, 스토커식보다는 유동층식 소각로에서 비산재가 많이 발생되며, 대기오염방지시설의 유해가스 처리에 쓰이는 소석회의 양에 따라서도 다를 수 있는 것이다.In the present invention, the fly ash used in the present invention contains heavy metals such as lead, cadmium, and zinc, and dioxins. Since fly ash is a particulate matter having micro or less size, if it is not carefully handled, The electrostatic precipitator and the bag filter usually have a particulate matter removal efficiency of 99% or more. Therefore, they must be removed from the pollution prevention facility using a vacuum conveyor and then transported using a sealed container. The amount of generated dust varies depending on various conditions. Depends on the physico-chemical properties of the refuse and the treatment technology. Fossil fuels are generated more frequently in the fluidized-bed incinerator than in the stoker type, and may vary depending on the amount of lime that is used in the treatment of harmful gases in air pollution control facilities.
상기 산업폐기물 중 알루미늄광재는 알루미늄 용해 시 발생되는 분진류로서, 알루미늄 용해 공정에서 발생하는 "드로스(dross)"라 불리는 알루미늄 산화물은 소정의 공정을 거치면 알루미늄을 회수할 수 있는 알루미늄분을 함유하고 있으며, 알루미늄분을 회수해도 여전히 대량의 알루미늄광재가 남으며, 본 발명에서는 이러한 알루미늄광재를 사용하며, 현재 알루미늄광재는 제강용첨가제로 재이용되거나, 산업폐기물로 투기 및 폐기되고 있으며, 불법투기는 물론이고 합법적인 투기 및 폐기의 경우에도 처리할 때까지 알루미늄광재는 그냥 쌓아두며, 이 순간에도 유해한 화합물이 생성되어 주변 환경을 파괴하는 등 사회적 문제도 많이 되고 있으나, 본 발명에서는 이러한 분진류의 알루미늄광재를 고형화시켜서 환경파괴를 예방토록 하는 것이다.Among the industrial wastes, the aluminum slag is a dust stream generated when aluminum is melted. The aluminum oxide called "dross " generated in the aluminum melting process contains an aluminum component capable of recovering aluminum through a predetermined process In the present invention, such an aluminum slag is used. Currently, the aluminum slag is reused as an additive for steelmaking, is dumped and disposed as industrial waste, and is used not only for illegal dumping Even in the case of legal dumping and disposal, the aluminum slag is piled up until it is processed. At this moment, harmful compounds are generated and the surrounding environment is destroyed. However, in the present invention, And solidify it to prevent environmental destruction.
그리고 상기 혼합폐기물에 사용되는 산업폐기물인 금형에 사용되고 버려지는 (화학)폐주물사 및 석재 가공 시 발생되는 폐석분을 경화재인 시멘트를 혼합하여 시멘트와 물의 수화반응(水和反應)에 의해서 성형 후 양생시켜서 고형화시키게 되면 이러한 폐주물사와 폐석분은 본 발명에서 콘크리트의 모래와 자갈 등과 같은 골재 역할을 하게 되는 것이다.The waste wastes generated during the (chemical) waste sand and the stone processing used in the mold, which is the industrial waste used in the mixed waste, are mixed with the cement which is the hardening material and cured by the hydration reaction of the cement and water, If the solidification is made, the waste sand and waste lime are used as aggregates such as sand and gravel of concrete in the present invention.
상기 시멘트에 혼합되는 점토 또는 황토는 0.002~0.005mm의 크기를 갖는 청정한 미세분말의 성상을 가지며, 상기 점토와 황토의 크기가 0.002mm 이하가 되면 분쇄 및 운송과 보관이 어려워지며, 크기가 0.005mm 이상이 되면 응집력이 떨어지게 되며, 상기 점토와 황토는 깨끗한 곳에서 채취되어 미 분쇄된 것으로서, 응집력이 월등하여 시멘트와 같이 경화재로 사용 시 고형체의 강도를 높일 수 있으며, 석회질의 시멘트보다 자연 친화적이므로 매립 후 토양을 파괴할 우려가 급격히 낮출 수 있는 것이다.The clay or loess mixed in the cement has a fine fine powder having a size of 0.002 to 0.005 mm. When the size of the clay and the loess is less than 0.002 mm, it becomes difficult to crush, transport and store. When the size is 0.005 mm The clay and loess are collected in a clean place and finely pulverized. Since the cohesive force is high, the strength of the solid body can be increased when it is used as a hardening material such as cement, and it is more environmentally friendly than calcareous cement The risk of destroying the soil after landfilling can be drastically reduced.
또한 상기 시멘트와 물에 중량비 2:2:1로 혼합되는 오니(汚泥)의 경우 하수처리 또는 정수과정에서 생긴 침전물로 주로 혐기처리 후 탈수하여 매립이 되고 있으며, 응집력과 함수율이 높아서 혼합폐기물에 시멘트와 물을 혼합할 시 첨가하게 되면 산업폐기물의 고형체의 강도를 증가시키면서 별도의 매립 등으로 처리하지 않아도 되므로 산업폐기물의 처리 효율을 월등히 향상시킬 수 있는 것이다.In the case of sludge mixed with cement and water at a weight ratio of 2: 2: 1, it is a precipitate formed in the sewage treatment or water purification process, and is mainly dewatered after anaerobic treatment and is buried. Since the cohesion and water content are high, And water are added, the strength of the solid body of the industrial waste is increased, and it is not necessary to treat the waste by separate landfill, so that the treatment efficiency of the industrial waste can be greatly improved.
