Objective This study aims to identify the persistent, migratory and toxic (PMT) high-risk substances in the organic pollutants of shale oil volume fracturing flowback water and explore their degradation-transformation pathways. Method The organic components in the flowback water from fracturing were analyzed by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) techniques. Based on the BioWIN model prediction and threshold analysis method, PMT substances were screened out. Result Six PMT substances were screened out from the fracturing flowback water. Such as Triethyl phosphate, Tributyl phosphate, Dibutyl Phosphate, Naphthalene, 1-Methyl naphthalene, 2-Methyl naphthalene. After being treated with Fe2+ -activated percarbonate (SPC) oxidation, the persistence and biological toxicity of the typical PMT substances were significantly reduced. Conclusion The Fe2+/SPC oxidation technology can effectively reduce the environmental risks of PMT substances, providing technical support for the treatment and risk prevention of the flowback water from shale oil fracturing.

目的 识别页岩油体积压裂返排液中持久性、迁移性和有毒 (persistent, mobile, toxic, PMT) 高风险物质并探究其降 解−转化路径。方法 采用气相色谱−质谱联用与液相色谱−质谱联用技术分析了压裂返排液中有机组分, 基于 BioWIN 模型 预测与阈值分析法筛选出 PMT 物质。结果 从压裂返排液中筛选出 6 种 PMT 物质, 分别是磷酸三乙酯、磷酸三丁酯、磷酸 二丁酯、萘、1−甲基萘、2−甲基萘。经过 Fe2+活化过碳酸钠 (sodium percarbonate, SPC) 氧化处理后, 典型 PMT 物质的持久性 与生物毒性显著降低。结论 Fe2+/SPC 氧化技术能有效降低 PMT 物质环境风险, 为页岩油压裂返排液的处理与风险防控提 供技术支撑。 [ABSTRACT FROM AUTHOR] |
