Effects of Permeable Reactive Barriers for Treating Uranium Mine Pit Water

Conference paper
Part of the Environmental Science and Engineering book series (ESE)

Abstract

In this study, laboratory-scale Permeable reactive barrier (PRB) reactors were designed with the mixture of non-valent iron, active carbon, hydrated lime and quartz sands as reaction media. The feasibility and effectiveness of treating uranium mine pit water by PRB were tested under 3 different proportions of media through dynamic simulation tests, which came out the optimal proportion of contaminants. The result indicated that the remediation effect of reactor B was the best, whose average removal rate to U was up to 99%, as well as the average value of total α, total β, and 226Ra in effluent were 0.78 Bq/L, 3.52 Bq/L and 0.47 Bq/L respectively. The quality of effluent met the requirement of relevant standards, which indicated that the PRB technology is a feasible method for the treatment of uranium mine pit water.
