吸附和/或吸附法去除卤乙酸（HAAs）的特性 采用四种介质（包括陶瓷、颗粒活性炭（GAC）、生物陶瓷和生物活性炭）的柱试验进行生物过滤 进行了BAC。将二氯乙酸（DCAA）和三氯乙酸（TCAA）添加到一种真正的饮用水中，该饮用水取自 以地下水和地下水为目标消毒副产物（DBPs）。结果表明: 生物降解可以非常有效地去除HAA。随着时间的推移，去除效率也随之提高 接触时间变长。 当空床接触时间（EBCT）设定为15分钟时， 30min和60min，DCAA的去除率均接近100%，而TCAA的去除率接近100% 分别为60%、94%和100%。GAC在项目初期移除HAAs 这项实验是从碳吸附，而生物降解是主要的碳 HAA在实验后期被去除。包括16个参考文献、表格、图表。

The removal characteristics of haloacetic acids (HAAs) by adsorption and/or bio-filtration using column tests with four media including ceramic, granular activated carbon (GAC), bioceramic and BAC were conducted. Dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) were spiked in a true drinking water drawn from underground water and were used as the target disinfection byproducts (DBPs). The results indicated that biodegradation could remove HAA very effectively. The removal efficiency was higher as the contact time became longer. When the empty bed contact time (EBCT) was set at 15min, 30min and 60min, the removal efficiencies of DCAA were all nearly 100% while for TCAA were 60%, 94% and 100%, correspondingly. HAAs removal by GAC at the initial period of the experiment was from carbon adsorption, whereas biodegradation was dominated for the HAA removal later in the experiment.
