| Research Abstract |
Evaluation of water purification and consideration of the purification mechanism in drainage ditch with purified function were study objects. As a result, the purified function for nitrogen components has been kept since its improved, and the purification effect showed at the rainfall period as well as no rainy days. Moreover, it was confirmed that nitrogen purification depended on the denitrification greatly.
