摘要
纯氧曝气活性污泥法处理技术已在国外污水处理工程得到广泛应用,介绍了该技术的供氧方式、原理以及目前成熟的供氧系统,通过对比分析纯氧曝气与空气曝气在饱和溶解氧浓度、氧转移速率等技术参数和经济性能方面的差异,论述了纯氧曝气的突出优点。同时介绍了纯氧曝气工艺在城市污水处理、工业废水处理、河道污染整治等方面的工程应用情况。
The treatment technology by pure oxygen aeration activated sludge process has been widely used in the foreign wastewater treatment projects.The article introduces the oxygen supply mode and principle of this technology,and the present well-known oxygen supply system.Through the comparison and analysis of the pure oxygen aeration and the air aeration in the differences of technical parameters and the economical performances of saturated dissolved oxygen concentration and oxygen transferring velocity,the article discusses the prominent advantages of pure oxygen aeration,and also introduces the engineering application of pure-oxygen aeration technology in the urban sewage treatment,industrial wastewater treatment and river pollution harnessing.
