这是一个由五部分组成的系列的最终报告，该系列总结了现有的处理技术，以满足国家无机物初级饮用水临时法规的要求。介绍了去除钡和放射性核素的处理技术，重点介绍了美国环保局饮用水研究部门进行的实验室罐试验和中试工厂研究。在可用的情况下，还提供了全面的治疗数据。讨论的主要处理技术有常规混凝、石灰软化、活性炭吸附、离子交换和反渗透。还对每种污染物的健康影响和化学性质进行了一般性讨论。包括43个参考文献、表格和图表。

This is the final report of a five-part series that summarizes the existing treatment technology to meet the National Interim Primary Drinking Water Regulations for inorganics. Treatment technology for the removal of barium and radionuclides is presented with emphasis placed on laboratory jar test and pilot plant studies conducted by the Drinking Water Research Division of USEPA. Where available, full-scale treatment data also are presented. The principle treatment techniques discussed are conventional coagulation, lime softening, activated carbon adsorption, ion exchange, and reverse osmosis. A general discussion of the health effects and the chemistry of each contaminant is also presented. Includes 43 references, tables, figures.
