摘要
本文从氧化沟的起源、运行方式、技术发展提出ＤＥ型氧化沟，并分析了ＤＥ型氧化沟脱氮除磷的工艺特点，又根据国内氧化沟的设计经验提出如何计算ＤＥ型氧化沟的容积。
Based on the origin of oxidation ditch, itS running pattern, the development of its technology, this paper puts forward DE-type oxidation ditch, and analysizes the biological denitrification and dephasphorization technology featunes of DE-type oxidation ditch. Ferther more, if shows how to calculate the volume of DE-type oxidation ditch according to the internal experience of designing oxidation ditch.
