常用曝气系统在城市给水工程中的应用对比

Competitive Study of Common Aeration System Application in Urban Water Supply Project

生物接触氧化法作为城市给水工程生物预处理工艺,近年来得到了日益广泛的实际应用。本文对给水生物接触氧化法预处理工艺中常用的两种曝气系统(微孔曝气器曝气和穿孔管曝气)作了简单介绍,并结合中试试验和工程实践对这两种不同曝气系统作了充氧性能、系统造价、运行成本及运行管理等方面的比较分析。研究表明,在实际污水处理厂生物池曝气系统应用中,采用微孔曝气器的曝气系统优于采用穿孔管的曝气系统。

As biological pretreatment process of urban water supply project,biological contact oxidation has been applied widely in practical application.This paper briefly introduces two kinds of aeration systems（Microporous Aerator Aeration System and Perforated Pipe Aeration System） usually adopted in pretreatment process of water supply biological contact oxidation.The comparative analysis of oxygenation capacity,system cost,operation cost and operation management of these two kinds of aeration systems were conducted in connection with pilot test and project practice.Researches show that Microporous Aerator Aeration System outperforms Perforated Pipe Aeration System in sewage treatment plant aeration system application.
