| Abstract: | Usually it is considered that the nitrate reduction column should be reactivated if the reduction efficiency is less than 95 %,because the reduction column has low reduction ability, but this study indicated that the low reduction efficiency may also caused by excessive reduction. A simple experiment method to determine whether excessive reduction has occurred was introduced, and the factors which influenced the excessive reduction degree were discussed. |
