The purposes of this study are to measure environmental condition of the contaminated area and to evaluate remedial efficiency of microbial agents in the contaminated sediment. For this purpose sediments were collected from two different locations, dangdong and danghangpho in the wonmun bay, southeast coast of Korea. Three microbial agents such as Bacillus Bacteria (A), mixture of montmorillonite (B) and biogranula (C) were applied onto contaminated bay sediment to activate microbial population. Geochemical parameters such as chemical oxygen demand (CODMn), total phosphorus (T-P), total nitrogen (T-N), and acid volatile sulfide (AVS) were measured to know environmental condition of the contaminated area. The remedial efficiency of microbial agents was calculated with compared to control sediment within 28 days. The bacterial growth of microbial agents was observed by the total viable count (TVC) method. Those microbial agents were found to reduce chemical oxygen demand (CODMn), total phosphorus (T-P), total nitrogen (T-N), and acid volatile sulfide (AVS) value. Pollutant removal efficiency order of microbial agents were found as microbial agent A > microbial agent B > microbial agent C. These results showed that microbial agent A can reduce chemical oxygen demand (CODMn), total phosphorus (T-P), total nitrogen (T-N), and acid volatile sulfide (AVS) value in the contaminated sediments. Microbial agent A is available in market, easy to spray and comparatively low cost. Therefore the Bacillus Bacteria is a promising agent for remediation of contaminated sediments.
