本研究的目的是提供足够的信息，以指定并建立一种经济高效的处理工艺，以满足拟议的饮用水中砷含量为10 ug/L的新欧洲标准。进行了实验室规模的测试，以评估许多治疗方案的相对效率。这些措施消除了颗粒活性炭（GAC）和絮凝作为可能的处理工艺。随后进行了中试试验，以确定砷在几种不同介质中的吸附特性，包括不同网目尺寸的活性氧化铝、活性铝土矿、粒状氢氧化铁、离子交换树脂和催化二氧化锰。本文主要研究活性氧化铝，它被证明是最可行的介质。

The objective of this study was to provide sufficient information to specify and build a cost effective treatment process to meet the proposed new European standard of 10 ug/L for arsenic in potable water. Laboratory scale tests were undertaken to assess the relative efficiencies of a number of treatment options. These eliminated granular activated carbon (GAC) and flocculation as possible treatment processes. Subsequent pilot-scale trials were then carried out to determine the adsorption characteristics of arsenic with several different media including activated alumina of various mesh sizes, activated bauxite, granular ferric hydroxide, ion exchange resin and catalytic manganese dioxide. This paper concentrates on activated alumina which was demonstrated to be the most viable media.
