This study is discussed water purification and leaching ability of tidal flats sediment in Ishaya Bay Site .Water purification ability evaluate as decreasing of previously adjustment of nitrogen, phosphorus concentration in synthetic sea water using batch experiments. First of all, the factor of water purification ability is classed using compared sediment and sterilized sediment Ammonia was decreased by microbiological activities, and nitrate was decreased by microbiological activites and absorption, phosphorus decreased by absorption. Dentrification and Nitrification can applied Line weaver-Burk equation , decreased of Nitrate and phosphorus can applied Feundlich equation. Maximum denitrification and nitrification are 10.79 and7.24 µg/(g d), respectively. Effect of salinity on denitrification rate is bigger than nitrification rate. Secondly, leaching ability was examined using column experiment when 3.4% and 1.7% salt synthetic sea water. The ammonia concentration increasing with time, after that it's nitrified to nitrate.
