Environmentally benign method of landfill liner improvement
The present invention relates to a technique for inducing an enzyme induced carbonate precipitation (EICP) using low-priced materials, calculating a mixture ratio for generating an optimal amount of calcium carbonate, and improving a water barrier layer for a waste landfill facility using the reaction. The water permeability coefficient and the rigidity of a water barrier material for the waste landfill facility can be improved by using the EICP reaction. In the reaction of calcium carbonate using an enzyme, raw soybean flour is applied without going through the process of extracting enzymes from microorganisms and soybeans and materials applicable in the field such as calcium chloride for snow removal and urea for fertilizer are used, thereby satisfying economic efficiency and field applicability. Moreover, a large amount of sulfate detected in the leachate can be removed.
본 발명은 저렴한 재료를 이용하여 탄산칼슘 생성반응 (Enzyme Induced Carbonate Precipitation, EICP)을 도모하고 탄산칼슘의 최적생성량 배합비를 산정, 이 반응을 이용하여 폐기물 매립시설의 차수층을 개선하는 기술에 대한 것으로, 효소를 이용한 탄산칼슘 생성 (Enzyme Induced Carbonate Precipitation, EICP) 반응을 이용하여 폐기물 매립시설 차수재의 투수계수 및 강성도 개량 향상시킬 수 있도록하며, 효소를 이용한 탄산칼슘 반응 시, 미생물과 콩에서 효소를 추출하는 과정을 거치지 않고 생콩가루를 적용하며, 현장적용이 가능한 재료(제설용 염화칼슘, 비료용 요소 등)를 사용하여 경제성과 현장적용성을 충족시킬 수 있으며, 침출수에서 다량 검출되는 황산염을 제거할 수 있게 된다.
