水体中内分泌干扰物的高效脱除与多技术组合联用

Research progress of hybrid systems for EDCs efficient removal in water

水体中内分泌干扰物(EDCs)种类繁多、理化性质各异、浓度低但危害高,严重威胁着人类和动植物的生命安全。单一的物理、化学或生物处理技术在水体痕量EDCs的去除过程中,存在效率低、能耗高等问题,而通过多种去除技术组合联用的方式,可有效提升水体EDCs的脱除效率。综述了生物、物理、化学去除技术组合联用工艺在水体内分泌干扰物去除中的应用,重点介绍了活性污泥处理、膜生物反应器、膜过滤分离、活性炭吸附和高级氧化等技术的组合联用对水体中EDCs去除的相关研究和进展。通过对不同技术组合特点的对比分析,提出纳米技术与绿色可持续技术的组合联用将是未来EDCs去除技术发展的重要方向。

Many endocrine disrupting compounds(EDCs) existed in pharmaceuticals, personal care products and furniture. EDCs are frequently detected in surface water and ground water since they are survived from convenient water and wastewater treatment plants. This review presents an insight on hybrid systems combining biological, physical and chemical treatments for fast and eco-efficient EDCs removal in water. Typical hybrid systems consisted of activated sludge process, membrane bioreactor, membrane filtration process, activated carbon adsorption process and advanced oxidation process are summarized, and the characteristics of different hybrid systems are comparatively analyzed. Moreover, the application of hybrid nanotechnologies and green sustainable technology are suggested for EDCs removal in future.
