本文介绍了在采用臭氧氧化和生物过滤的全规模处理厂中形成和去除羧酸的数据。臭氧氧化后羧酸浓度增加，后续过滤后羧酸浓度降低。主要水质参数（如温度、pH值）与酸形成之间不存在简单的线性关系。臭氧氧化的羧酸产率比相应的醛高一个数量级。从实用角度来看，经验线性模型可以描述通过生物过滤去除羧酸的过程。然而，数据表明，去除机制可能很复杂。尽管过滤器中的接触时间相当长（约30分钟），但几种羧酸的去除是不完整的（e。 g、 ，甲酸盐的平均出水浓度为44 ug/L）。包括28个参考文献、表格和图表。

This article presents data on the formation and removal of carboxylic acids in a full scale treatment plant employing ozonation and biological filtration. Carboxylic acid concentrations increased after ozonation and decreased through subsequent filtration. Simple linear relationships between major water quality parameters (e.g., temperature, pH) and acid formation did not exist. Yields of carboxylic acids on ozonation were an order of magnitude greater than for the corresponding aldehyde. An empirical linear model could describe the removal of carboxylic acids through biological filtration from a practical point of view. However, the data suggest the removal mechanism may be complex. Although contact times in the filters were quite long (on the order of 30 min), removal of several carboxylic acids was incomplete (e.g., average effluent concentration of formate was 44 ug/L). Includes 28 references, tables, figures.
