YH만 해양오염퇴적물 정화사업 부산, 대한민국

Abstract

Contaminated sediment sites in S. Korea are largely close to residential and business districts in the metropolitan port cities. We are reporting here the YH Bay remediation project carried out from 2009 to 2012. The Administration decided that 59,000 m3 of the contaminatedsediment had to be removed and this dredged material be placed in a near-shore reclaimation facility in the vicinity of YH Bay. As the reclaimed area is subject to the Soil Environment Conservation Act, about 30% of the total dredged material was required to have its heavy metal content reduced below the concern level of this Act, particularly for zinc. Through bench scale comparison tests, the best current available technology from among competing vendors was selected.that 59,000 m3 of the contaminatedsediment had to be removed and this dredged material be placed in a near-shore reclaimation facility in the vicinity of YH Bay.
