초록
최근 수십년간의 산업발달 및 인구증가에 따라 산업폐수 및 각종 비점오염원의 유입으로 수질오염이 심각한 실정이다. 이에 대해 국내및 국외에서 이에 대한 연구가 활발히 진행되고 있다. 본 연구에서는 유기물질의 분해효과가 있는 유용미생물과 포러스콘크리트를 이용하여 하천 현장에 설치하여 구조적 성능평가와 장기간 수질정화능력을 평가하였다. 구조적 성능평가 결과, 시험체의 공극률은 15%가 적절하다고 판단되며, 또한 수질정화성능 검토 결과 각항목에 대한 제거율은 SS 34.1%, BOD 14.6%, COD 34.9%, T-N 11.4%, T-P 12.6%를나타냈다. 따라서 유용미생물을 이용한 포러스콘크리트의 현장적용시 수질을 정화시키는데 효과적이라고 판단된다.
Abstract
In recent years, a rapid growth in the population and urbanization led to an increasing industrial growth. The inadequatetreated-wasted water from industry and various non-point sources causes significant negative effects on the stream water. For pastfew decades, extensive researches have been performed on water purification process. The purpose of this study is to investigatemechanical performance and water purification properties of porous concrete by using effective microorganisms through the siteassessment test. The mechanical performance evaluation results showed that the increase void ration caused an decrease in thestrength. The optimal mix rate was found to be 15% void rate From the site assessment, it was evaluated that the porous concreteimproved the quality of the water and the purification ratios are 34.1 for SS, 14.6% for BOD, 34.9% for COD, 11.4% for T-N,and 12.6% for T-P. The porous concrete and the related purification technique can reduce the non-point pollution sources flowinginto the river.
