摘　　要：人工湿地是国内外应用较为广泛的一种污水处理技术。近年来,人工湿地的环境卫生安全问题越来越受到人们的关注。人工湿地中病原微生物的去除或失活受到诸多因素的影响,其过程和机制与传统的二级污水处理工艺有较大区别,选择适宜的指示微生物和病原微生物并研究其行为是进行人工湿地环境卫生安全评价的关键。本文论述了病原微生物在人工湿地中的归宿以及人工湿地可能对环境卫生安全造成的影响,综述了国内外的研究现状,指出了该方面研究的必要性和迫切性。Constructed wetland is one of the wastewater treatment technologies widely used in China and other countries. Recently, more and more attention has been paid to the environmental sanitary safety of constructed wetland during its utilization in wastewater treatment. Many factors in constructed wetland contribute to the removal of pathogenic organisms, and the removal or inactivation processes and mechanisms are different from those of traditional secondary sewage treatment. The key points of constructed wetland＇ s environmental sanitary assessment are the selection of proper pathogenic and indicator microorganisms, and the study of their behaviors in constructed wetlands. In this paper, the fate of pathogenic organisms in constructed wetlands and the potential negative impacts of constructed wetlands on ecological environmental safety were discussed, related research methods and achievements were summarized, and future research directions were pointed out.
