本文描述了20座城市水处理厂进水中铀去除的研究。这些工厂采用各种常规处理工艺组合，如混凝、沉淀、过滤和氯化。原水中的铀浓度范围为0.01 ug/L（检测限）至约16 ug/L，而处理水中的铀浓度范围为0.01 ug/L至约7 ug/L。然而，对于给定的电厂，处理水中的铀浓度并不总是低于原水中的铀浓度。讨论了pH值和化学明矾用量对铀去除的影响。包括25个参考文献和表格。

This article describes a study of uranium removal from influent waters at 20 municipal water treatment plants. The plants use various combinations of conventional treatment processes such as coagulation, sedimentation, filtration, and chlorination. The uranium concentration in the raw waters ranged from 0.01 ug/L (the detection limit) to approximately 16 ug/L, whereas that in treated waters ranged from 0.01 ug/L to approximately 7 ug/L. For a given plant, however, the uranium concentration in the treated water was not always less than that in the raw water. The effects of pH and chemical alum dosages on uranium removal are discussed. Includes 25 references, tables.
