- Abstract
With the development of uranium resource exploitation industry in China, uranium-containing wastewater pollution has become a non-negligible environmental problem. The treatment of uranium-containing wastewater with appropriate technology has been widely concerned. This paper reviewed the treatment techniques of uraniumcontaining wastewater, including the traditional processes, such as chemical precipitation, reduction curing, ion exchange, adsorption, microbial and electrodeposition and advanced processes including membrane separation and uranium immobilization into minerals. The application of each technique in the treatment of uranium-containing wastewater was briefly described and its mechanism was analyzed, and their advantages and disadvantages were analyzed and compared. It was concluded that the application of each method had significant specificity, and a combination of methods could be used in practical applications. Traditional treatment methods had the advantages of relative maturity, simple process and low cost and high efficiency, but they also had the disadvantages of poor selectivity, poor stability and secondary pollution. Traditional uranium-containing wastewater treatment methods stayed in the functionalization and modification of the original material, trying to constantly break through its upper limit of uranium treatment. Among the new technologies, membrane filtration method had the advantages of high automation, good separation effect and reusable permeate, but also had the problems of high cost, complicated process, membrane contamination and low permeate flux. Among those uranium-containing wastewater treatment processes, uranium immobilization into minerals had obvious advantages in the treatment of large quantities of uranium-containing wastewater. The recovery and reserve of uranium immobilization products as secondary uranium resources was the optimal method to realize the harmless and resource-based treatment of uranium-containing wastewater.
