【摘要】 类固醇雌激素(SEs)是水环境中高频检出的一类微量难降解有机物,其在我国大部分水体中的残留质量浓度往往超过欧盟规定的雌激素干扰效应质量浓度阈值1 ng/L,对生态环境及人体产生潜在健康风险,是影响二级生化尾水深度处理后安全再利用的重要污染物。综述了类固醇雌激素的理化性质、在水环境中的分布特征及其潜在环境风险,并对其主要的深度去除技术进行了总结。在此基础上,从新型吸附材料、经济高效的催化氧化技术、多污染物协同深度净化、组合工艺及反应器开发等四个方面展望了未来的研究趋势。更多还原

【Abstract】 Steroid estrogens(SEs) are a group of refractory organic micropollutants detected in aquatic environment frequently. Generally,their mass concentrations in aquatic environment of China are much higher than estrogen disruption effects mass concentration threshold of 1 ng/L,which results in potential health risks to the environment and human. They are vital pollutants affecting the safe reuse of secondary effluent after the advanced treatment. This study systematically reviewed that the physical and chemical properties,the distribution in aquatic environment and the potential environment risks of steroid estrogens. The main advanced removal techniques for steroid estrogens were also summarized. On this basis,the future research trends were proposed from four aspects including new adsorption materials,inexpensive catalytic oxidation technology,synergistic advance purification of multi-pollutants,development of combined process and reactors.更多还原
