복합 미생물제제를 이용한 해양준설토의 친환경처리에 대한 기초연구

Abstract

Most harbor areas in the country have been polluted by incoming wastewater from various sources, and this makes formation of deep contaminated sediment layers on the seafloor. The contaminated sediments should be digged out to keep harbors safe and navigable to increasingly large ships. The dredge wastewater generated during the dredging operation, however, contaminates the marine environment again.

This study investigated potential of mixed effective microorganisms, BM-S-1, for treating organic fine materials(less than 10 μm) contained in the dredge wastewater. This study also evaluated economic feasibility of the environment-friendly dredging using BM-S-1, and after deriving optimum design parameters, provided a design basis for the biological treatment process using BM-S-1.
