摘　　要：砷污染地下水已经成为全球关注的问题。由于砷影响人们的身体健康,因此饮用水标准中砷的浓度已经从50μg/L降低到10μg/L。为了更有效地去除地下水中的砷,许多新技术、新工艺孕育而生。各种工艺发展主要基于氧化、混凝沉淀、吸附、离子交换和膜技术。地下水中的砷往往与铁、锰共存,针对地下水不同的水质和砷浓度,就国内外现有技术和自主试验研究,对如何采取有效、适合的处理技术进行了探索,提出可采用经济、可靠、环境友好的曝气—生物氧化过滤工艺去除地下水中的砷。Arsenic contaminated groundwater has been a global hot topic. Due to the fact that arsenic might damage people＇s health, the standard of arsenic concentration in drinking water has been reduced from 50μg/L to 10μg/L. In addition, many new technologies and processes have been developed to remove the arsenic in groundwater effectively. The technologies which these new processes are mainly based on include oxidation, coagulation and sedimentation, adsorption, ionexchange, and membrane. The arsenic always coexists with the iron and manganese in groundwater. Based on currently existing domestic and abroad technologies and experiment study, this paper studied how to select the proper and effective treatment technology to deal with different ground-water quality and arsenic concentration; meanwhile, this paper also suggested that the aeration-bio- logical oxidation filtration might be used for groundwater arsenic removal which is a economic, reli- able, and environment-friendly process.
