摘　　要：新型高效脱氮合建式氧化沟(C-Orbal)是以Orbal氧化沟和周进、周出辐流式二沉池为基础,将厌氧池、缺氧池、好氧池、二沉池、内外回流与Orbal氧化沟组合在一起,具有占地面积小、投资省、水头损失小、能耗低、适应能力强、运行管理方便等优点。结合工程实例,介绍了该工艺的主要技术特点、处理效果及经济技术指标。Based on Orbal oxidation ditch and radial flow secondary sedimentation tank with peripheral feed and peripheral outflow, the new type combined Orbal oxidation ditch process for high-performance nitrogen removal is composed of anaerobic tank, anoxic tank, aerobic tank, secondary sedimentation tank, internal and external recycle systems and Orbal oxidation ditch. The process has advantages such as less land occupation, small investment, less head loss, low energy consumption, high sewage adaptability, convenient operation and management and so on. Taking an engineering for example, the main technical features, treatment effect and economic and technical indexes of the process are introduced.
