生物活性炭（BAC）工艺是将臭氧氧化与颗粒活性炭（GAC）吸附相结合的一种方法，已被提出作为一种提高GAC工艺去除有机物成本效益的方法。本文探讨了在美国传统饮用水处理中实施BAC工艺的效果。分析了臭氧氧化和氯化的几种组合对后续GAC吸附的影响。采用溶解有机碳（DOC）去除和挥发性卤化有机物（VHO）去除两种方法研究了预分层对GAC吸附的影响。 常规处理（加氯和不加氯）后再进行臭氧GAC，可提高DOC的生物降解性。臭氧氧化被证明会干扰GAC处理挥发性卤化有机物的能力，这表明臭氧单元工艺可能会产生低分子量有机物，与VHO竞争挥发性卤化有机物和天然背景有机物之间的吸附位置。包括34个参考文献、表格、图表。

The biological activated carbon (BAC) process, which is a combination of ozonation followed by granular activated carbon (GAC) adsorption, has been proposed as a method to improve the cost effectiveness of the GAC process for organics removal. This article examines the effects of implementing the BAC process within conventional US drinking water treatment. The effects of several combinations of ozonation and chlorination on subsequent GAC adsorption were analyzed. Dissolved organic carbon (DOC) removal and volatile halogenated organics (VHO) removal were used to evaluate the effects of preozonation on GAC adsorption. Conventional treatment (with and without chlorination) followed by ozone-GAC increased biodegradation of DOC. Ozonation was shown to interfere with the ability of GAC to treat volatile halogenated organics, suggesting that ozone unit processes may produce low-molecular-weight organics that compete with VHOs for adsorption sites between volatile halogenated organics and the natural background organics.
