本研究的目的是优化臭氧与生物处理在DBP控制中的应用。预臭氧化的特点是:产生臭氧化DBPs和BDOC；氯化DBP前体的氧化；溴化物转化为溴酸盐。测定了生物处理对DBP和DBP前体的控制效果。还特别注意了溴浓度对DBP形态形成的影响。氯化DBP前体的氧化通过总有机卤素（TOX）、总THMs（TTHMs）和总卤乙酸（THAAs）的生成电位变化来测量。

The objective of this study was to optimize the use of ozonation with biotreatment for DBP control. Preozonation was characterized by the: production of ozonation DBPs and BDOC; oxidation of chlorination DBP precursors; and conversion of bromide to bromate. The effectiveness of biotreatment was measured for the control of DBPs and DBP precursors. Special attention was also given to the impact of bromide concentration on the speciation of the DBPs. The oxidation of chlorination DBP precursors was measured by the change in formation potential for total organic halogen (TOX), total THMs (TTHMs) and total haloacetic acid (THAAs).
