Description
본 발명은 열탈착 공정 또는 생물학적 처리 공정을 이용한 오염 토양의 처리 방법에 관한 것이다.The present invention relates to a method for treating contaminated soil using a thermal desorption process or a biological treatment process.
환경오염원으로서 가장 큰 부분을 차지하는 각종 쓰레기 및 산업 폐기물은 최종적으로 매립지에 매립 방치된 후, 물, 토양, 대기 등의 다양한 매개체를 통해 이동하면서 변화와 변형을 계속하여 토양 오염, 지하수 오염 및 악취 등을 유발함으로써 인간을 포함한 자연 생태계에 영향을 미치고 있다. 그러나, 토양을 매개체로 한 토양 오염의 피해는 수질과 대기를 통한 오염의 피해보다 상대적으로 노출속도가 느리고 전달경로가 복잡하여 이에 관한 처리기술은 아직 정립화되지 않은 상태이다.Various wastes and industrial wastes, which constitute the largest part of the environmental pollution source, are finally landfilled and then moved through various media such as water, soil, and atmosphere, and continue to change and transform, resulting in soil pollution, groundwater pollution, and odors. By affecting natural ecosystems, including humans. However, the damage caused by soil-mediated soil pollution is relatively slower than the damage caused by water quality and air pollution, and the delivery route is complicated. Therefore, the treatment technology has not been established.
기존의 오염 토양의 정화기술로는, 예를 들어 원위치 처리법(in-situ)으로서 오염지역에 주입공을 여러개 실치하고 설치된 주입공에 고온의 증기를 주입함으로써 오염물질을 추출하는 토양 증기 추출법(soil vapor extraction), 오염 토양 주입공에 고화제를 투입하여 오염 토양을 고화처리하는 토양 고화법(soil solidfication), 미생물 및 영양물질을 주입공에 국부적으로 투입하여 유기 오염물질을 분해하는 미생물 분해법(bioremediation), 소각로를 이용하여 오염물질을 직접 소각하는 소각 처리법(incineration treatment) 등이 있다. 그러나, 국내의 경우 토양 환경 정화 기술에 대한 지식과 경험이 부족하여 그 처리기술 개발이 아직 미흡한 실정이고, 외국은 물리/화학적 처리기술 분야는 상대적으로 개발이 완료되어 그 적용단계에 있으며 원위치 처리의 미생물 분해법(in-situ bioremediation) 분야는 1970 년대부터 연구가 활발히 수행되기 시작하여 그 적용단계에 있다.Existing techniques for the purification of contaminated soil, for example, in-situ, soil vapor extraction method that extracts contaminants by placing multiple injection holes in the contaminated area and injecting high-temperature steam into the installed injection holes. vapor extraction), soil solidfication to solidify contaminated soil by injecting a solidifying agent into the contaminated soil injection hole, and bioremediation to decompose organic pollutants by locally injecting microorganisms and nutrients into the injection hole. ), Incineration treatment, which incinerators directly incinerate contaminants. However, in Korea, there is a lack of knowledge and experience in soil environment purification technology, and the development of treatment technology is still insufficient. In the foreign countries, the physical / chemical treatment technology field is relatively developed and is in the application stage. The field of in-situ bioremediation has been actively researched since the 1970s and is in its application stage.
이에 본 발명자들은 기존 기술에 비하여 신규성 및 진보성이 있는 열탈착 또는 생물학적 처리공법을 이용함으로써 우리나라에 방치되어 있는 1000 여개의 불량 매립장의 오염 토양을 안정화시켜 재활용(체육시설, 주차장, 화훼 단지, 축사, 경작지 등)할 수 있는 기술을 개발하여 본 발명을 완성하였다.Accordingly, the present inventors stabilized the contaminated soils of about 1000 poor landfill sites that are left in Korea by using thermal desorption or biological treatment techniques, which are novel and advanced compared to the existing technologies, and recycle them (sports facilities, parking lots, flower gardens, barns, farmland). The present invention was completed by developing a technology that can be used.
