城市污水处理厂应用纯氧曝气技术的探讨

近年来随着我国国民经济迅猛发展，对生活污水处理的要求也越来越高，运用纯氧曝气活性污泥工艺处理生活污水不失为一个良策。通过对青岛市即墨市污水处理厂扩建项目的分析，阐释了纯氧曝气的理论、工艺的选择以及纯氧曝气的经济性分析，论述了纯氧曝气技术在我国中小城市污水处理厂应用的可行性。随着国家新标准对污水脱氮除磷要求的增加．纯氧曝气在城市污水处理厂老厂的改造和新厂的建设中显示出很好的应用前景。

INVESTIGATION OF THE APPLICATION OF PURE OXYGEN AERATION TECHNIQUE IN SEWAGE TREATMENT

The requirements for wastewater treatment is getting higher and higher, as the national economy in China is developing rapidly . It would be a good method to use pure oxygen aeration technique in sewage treatment .By the analysis of the expansion project of Jimo sewage treatment plant , the paper discussed the theories of pure oxygen aeration technique , the selection of the technology and the economic analysis of pure oxygen aeration technique, discussed the feasibility of the use of pure oxygen aeration technique in sewage treatment .As the new national standards improved the requirement of nitrogen and phosphorus removal, pure oxygen aeration shows great prospects in the construction of sewage treatment plant.
