适合我国西部地区小城镇的污水处理工艺分析

Suitable for Our Western Small Towns of the Sewage Treatment Process Analysis

小城镇作为联结城市与乡村的经济纽带和区域性的行政、工商业中心,其在中国城市化、工业化过程中的作用是不可替代的。文章通过对我国小城镇常用的CASS工艺、Orbal(奥贝尔)氧化沟、A2/O工艺三种污水处理工艺的比较分析,认为CASS工艺是最适合我国西部地区小城镇污水处理工艺,并通过工程实例进一步证实了CASS工艺在西部小城镇污水处理过程中的实用性。

Small towns as the connection of urban, rural economic ties and regional administrative, commercial and industrial center, its role in the process of urbanization, industrialization in China is irreplaceable. Based on our small town common CASS process, Orbal （Aubert） oxidation ditch, A2/O process three kinds of comparative analysis of the sewage treatment process, think CASS process is the most suitable for our country in the western region small town sewage treatment technology, and through the engineering examples, further confirmed the CASS process of small towns in the west the practicality in the process of sewage treatment.
