The determination measure for distribution of NOM removal by two mechanisms in BAC was established. In this method, the change in DOC and BDOC of inflow and effluent was used to evaluate the distribution and to determinate the effect of the different ozone doses on the adsorption and biodegradation in BAC. The ozonation increased the concentration of BDOC in 0.12 - 0.54 mg/L with ozone dose of 2 - 8 mg/L and BAC filtration decreased concentration of BDOC to 0.23 - 0.31 mg/L. Moreover the biodegradation distribution to remove the organic pollutants increased from 46% to 89% with ozone dose of 2 - 8 mg/L.
建立了测定生物活性炭（BAC）中两种机制去除天然有机物（NOM）分布的方法。该方法利用进水和出水溶解性有机碳（DOC）和生物可降解溶解性有机碳（BDOC）的变化来评估分布情况，并确定不同臭氧剂量对BAC中吸附和生物降解的影响。臭氧投加量为2 - 8mg/L时，臭氧化作用使BDOC浓度增加0.12 - 0.54mg/L，而BAC过滤使BDOC浓度降至0.23 - 0.31mg/L。此外，随着臭氧投加量从2 - 8mg/L增加，去除有机污染物的生物降解分布从46%增加到89%。
