Abstract

The objective of this study was to investigate the removal and transformation of dissolved organic matter (DOM) through laboratory-scale soil aquifer treatment (SAT) soil columns. Using XAD resins, DOM was fractionated into 3 fractions: hydrophobic acid (HPO-A), transphilic acid (TPI-A) and hydrophilic fraction (HPI). Laboratory-scale SAT columns reduced about 58.64%, 41.86% and 68.51% of HPO-A, TPI-A and HPI, respectively. All samples studied exhibited a common general relationship with respect trihalomethane formation potential (THMFP): HPO-A > HPI > TPI-A. Specific ultraviolet light absorbance (SUVA) and specific trihalomethane formation potential (STHMFP) values for various DOM fractions increased across the SAT columns. HPI exhibited greater increase in SUVA and STHMFP than HPO-A and TPI-A. The STHMFP of HPO-A was greater than that of corresponding TPI-A and HPI fractions in all samples.

摘要

本研究的目的是通过实验室规模的土壤含水层处理（SAT）土柱来研究溶解有机物（DOM）的去除和转化。使用XAD树脂，将DOM分为3个组分：疏水酸（HPO-A）、亲脂酸（TPI-A）和亲水组分（HPI）。实验室规模的SAT柱分别降低了约58.64%、41.86%和68.51%的HPO-A、TPI-A和HPI。所有研究样品在三卤甲烷生成势（THMFP）方面呈现出共同的一般关系：HPO-A > HPI > TPI-A。不同DOM组分的比紫外吸光度（SUVA）和比三卤甲烷生成势（STHMFP）值在SAT柱中均有所增加。HPI的SUVA和STHMFP增幅大于HPO-A和TPI-A。在所有样品中，HPO-A的STHMFP均大于相应的TPI-A和HPI组分。
