Ltd., W uxi 214205,China) Abstract: 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 engineering for example, the main technical features, treatment effect and economic and technical indexes of the process are introduced. Key words: Orbal oxidation ditch; secondary sedimentation tank with peripheral feed and peripheral outflow; high-performance nitrogen removal 1 设计进、出水水质 4 3 2006 年 11 月河南方城县城市污水处理厂示范工程（近期规模为 1. 25 ×10 m /d ）竣工投产并 于 2007 年 11 月 28 日通过
