Rapid industrialization has brought Nam-Hae area serious environmental problems associated with released oil and other hydrocarbons. In this work, in order to enhance the quality of the shoreline sediment we made enviro-chemical analyses of its substances, TPHs and microbial growth after treating with oxygen releasing compound(ORC) such as MgO2. Total organic compound(TOC) was reduced from 33.45% to 25.1∼31.08% meanwhile COD decreased from 27.5∼28.9mg/g·dry to 19.9∼26.1mg/g·dry for input of 2∼10% MgO2 in 20days. For 10% MgO2 input, TP and TN were reduced by 13.3% and 18.8%, respectively. Most of all TPH was decomposed by max. 42.4% in 21days, and the total viable count of microbes was found to be exponentially increased by 75.9%.
