摘　　要：页岩气开发过程中会产生大量压裂返排液,这类废水由于具有生物毒性大、可生化性差和难处理的特点而备受广泛关注,如不经处理而回用或外排,会对环境和生态系统带来潜在危害和风险。总结分析了压裂返排液对水生生物和陆生生物的生物毒性研究进展,相关研究表明废液中盐、金属离子、有机组分是生物致毒的主要原因。未来需加强返排液特征污染物识别分析,完善致毒机理解析,重视返排液回用与生物毒性变化等实际问题,以期为治理油气田开发污水以及生态环境保护提供科学依据。During the development of shale gas,a large amount of fracturing flowback fluid will be produced.This type of wastewater has attracted wide attention due to its high biological toxicity,poor biodegradability and dificult to treat.If reused without treatment,it will bring potential harm and risk to the environment and ecosystem.This article summarizes and analyzes the research progress of the biological toxicity of this kind of sewage to aquatic and terrestrial organisms,and expounds that salt,metals,and organic components are the main causes of biological toxicity.Based on this research,it is necessary to strengthen the identification and analysis of the characteristic pollutants of the flowback fluid in the future,improve the analysis of the toxic mechanism,and pay attention to practical issues such as the reuse of the flowback fluid and changes in biological toxicity.It is expected to provide a scientific basis for the treatment of oil and gas development wastewater and ecological environment protection.
