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.

以具有净化功能的排水沟的净水评价和净化机理的探讨为研究对象。结果表明，对氮素组分的净化功能自改进以来一直保持不变，在雨季和非雨天均表现出净化效果。此外，还证实了氮素净化在很大程度上依赖于反硝化作用。
