  • 본 연구에서는 건설폐기물의 실질적인 재활용율을 높이고자 건설폐기물의 발생단계인 해체공사 현장에서 사용할 수 있는 소형의 이동식 분리 선별 장치를 개발하고 이에 대한 선별 효율성능을 평가하였다. 개발한 장치는 상당수의 해체현장이 도심지에 소재한다는 점을 고려하여 협소한 현장여건과 해체현장에서 수행되는 다양한 공정을 고려하여 $15m^2$ 면적 이내에서 1개의 암롤박스를 하루에 처리할 수 있는 16ton의 용량의 이동식 소형 분리 선별 장치를 개발하였다. 개발한 장치의 효율성능을 평가하기 위하여 트롬멜 회전속도 RPM 2~3, 4~6, 7~8에 대하여 10회씩 분리 선별을 실시하였고 그 결과 RPM 6~7에서 가장 높은 약 90%의 효율로 투입폐기물을 성상별로 분리하였다.

  • Landfill Mining is becoming more widely used in many closed landfill sites in the world. Many of existing landfills will be excavated inevitably owing to building the clean environment with the new structures and developing the cities in cramped country. This paper aimed at the introducing the design technology of the trommel screen and its in-site applied performance of the trommel screen system through experiments , which system is under developing by one of the national project and the analysis results of influencing factors to the environment . The result of the theoretical estimation agrees well with the experimental data, so that the sorting system could be able to be applied with the requirements of the purpose of end-items. As a result of the analysis, any hazardous materials including heavy metals met the limitions of the criteria in this experiment. In geotechnical enngineering, it will. desireable to use the sorted soils mixing with another soils in accordance with the requirements of the usages.

  • In this study, a real-sized experimental equipment (pilot plant) was built at the site based on the preliminary research data to develop a movable separator for the mixed construction waste that can be implemented in agricultural areas to review its feasibility through the evaluation of its separation efficiency by waste types. The final construction of the movable separator and experimental results of the separation efficiency are summarized as follows. 1) The separation performance according to the blade type was the best for the combustible wastes either with 26 numbers of L-type blades and 32 numbers of pin type blades. As far as combination of blade types, when the L-type and pin-type were combined, the best separation efficiency was achieved. 2) The separation efficiency for waste wood by the conveyor type and angle of inclination (slope) of the trommel was the best when the conveyor had ribs of seagull shape with the angle of inclination 45°. 3) The separation efficiencies by process showed that 65.9% was separated as inorganic demolition wastes, 18.2% as waste woods, and 16.0% as combustible wastes at conveyor speed of 2-3 rpm, and the error rate was the least from the waste types generated in the dismantle site.
