本研究的目的是评估一种磁性离子交换树脂用于 连续流动中试规模的天然有机物和溴化物去除 在不同的操作条件和原水特性下。最重要的 操作变量是有效树脂剂量（ERD），它是稳态的产物 接触器中的树脂浓度和再生率。原水 本研究中使用的紫外线（UV）吸收剂浓度适中 物质和溶解有机碳（DOC），以及低浊度、碱度和 阴离子物种的浓度。实验是使用环境原材料进行的 水和原水中加入了溴化物、氯化物和硫酸盐。提高ERD 导致紫外线吸收物质和DOC的去除增加。中度溴化物 根据ERD实现了移除。增加硫酸盐浓度 导致紫外线吸收物质、DOC和溴化物的去除率降低。包括22个参考文献、表格和图表。

The objective of this research was to evaluate a magnetic ion exchange resin for the removal of natural organic material and bromide on a continuous-flow pilot-scale basis under different operating conditions and raw water characteristics. The most important operating variable was the effective resin dose (ERD), which is the product of the steady-state resin concentration in the contactor and the regeneration ratio. The raw water employed in this study had a moderate concentration of ultraviolet (UV)-absorbing substances and dissolved organic carbon (DOC), and a low turbidity, alkalinity, and concentration of anionic species. Experiments were conducted using the ambient raw water and raw water spiked with bromide, chloride, and sulfate. Increasing the ERD resulted in increased removal of UV-absorbing substances and DOC. Moderate bromide removal was achieved, depending on the ERD. Increasing the sulfate concentration resulted in decreased removal of UV-absorbing substances, DOC, and bromide. Includes 22 references, tables, figures.
