摘　　要：硒作为生命体系必需的特殊微量元素,其必需浓度和毒性浓度之间的差距较小,易引发水体硒污染,进入人体后导致硒中毒。为此,本文从硒的来源及危害入手,在分析硒的水质指标的基础上,探究生物处理技术在水体硒污染中的应用,分析讨论影响水体硒污染生物处理效果的重要因素,以期促进生物处理技术在水体硒污染处理中的进一步推广应用。Selenium,as a unique trace element essential for life,has a small difference between its necessary and toxic concentrations,making water bodies susceptible to selenium pollution,which can lead to selenium poisoning upon ingestion.This paper starts by discussing the sources and hazards of selenium,and based on the analysis of water quality indicators for selenium,explores the application of bioremediation technologies in addressing selenium pollution in water bodies.It further analyzes and discusses the significant factors influencing the effectiveness of bioremediation for selenium pollution in water bodies,with the aim of promoting the further application and widespread adoption of bioremediation technologies in the treatment of selenium pollution in water bodies.
