臭氧-生物活性炭工艺设计中工程方案的选择

Selection of Engineering Scheme in Ozone/Biological Activated Carbon Process Design

臭氧-生物活性炭(O3-BAC)工艺是在生物活性炭工艺基础上发展起来的,是目前世界上公认的去除饮用水中有机污染物、嗅味等较为有效的深度处理工艺之一。随着《生活饮用水卫生标准》(GB 5749—2006)的实施,臭氧-生物活性炭工艺广泛应用于给水厂的提标改造中。在其设计中,臭氧气源的选择和活性炭池池型的设计关系到工程的投资、运行成本的高低以及操作管理的难易,需根据各给水厂的实际情况,合理选择臭氧气源和活性炭池池型,以利于给水厂提标改造工程的实施。

Ozone/biological activated carbon （O3/BAC） process was developed on the basis of bi- ological activated carbon process, which is recognized as one of the most effective advanced treatment processes in removing organic pollutants and odor from drinking water in the world at present. With the implementation of the Standards for Drinking Water Quality （ GB 5749 - 2006 ）, O3/BAC process has been widely used in upgrading and reconstruction of water treatment plants. In the design, selection of gas source for ozone generator and design of activated carbon tank type related to project investment, op- eration cost and operation management. In order to facilitate the upgrading and reconstruction project of water treatment plants, it needs to choose the ozone source and tank type reasonably according to the ac- tual situation of the plant.
