• 摘要：污染物的多介质/多界面行为影响其赋存状态、迁移转化及生物生态效应.阐明污染物界面行为及其调控技术原理,是准确认识污染物源汇机制、预测其生物有效性、发展污染控制新材料与新技术的重要基础.本文介绍了典型有机污染物的多介质界面行为及其微观机制,表面活性剂调控有机污染物固-液界面分配行为及生物有效性的基本原理,重点阐述了污染物界面行为调控技术在难降解有机废水吸附处理、土壤有机污染缓解与修复中的应用.

• Abstract：The multi-interfacial behavior of pollutants in multi-media affects their states of existence, transformation, transport and fate as well as biological and ecological impacts. Knowledge of the multi-interfacial behaviors and controlling principles of pollutants is vital not only for understanding the source-sink distribution mechanisms, predicting their bioavailability, but also for developing new pollution control materials and methods. This paper reviewed the multi-interfacial behaviors of typical organic pollutants and their micro-interface sorption mechanisms; elucidated the principles by which surfactants regulate the partition behavior of organic pollutants between solid-solution interface and their bioavailability, with a special focus on the application of these interfacial behaviors controlling technologies in regulating the sorption treatment of wastewaters containing non-degradable organic pollutants, mitigation and remediation of the organic contaminated soils.

• Key words：organic pollutants  interfacial behavior  bioavailability  controlling technology  wastewater treatment  soil remediation
