Application and Research Progress of PRB for Groundwater Pollution Remediation

Because of its long processing time,low operating cost,simultaneous processing of multiple pollutants,PRB( permeable reactive barrier) is a commonly used technique for groundwater pollution remediation in western countries. But relative research about the PRB technology in China is still in its infancy. We reviewed the PRB structure,PRB repair mechanism and application progress at home and abroad. Aiming at the problems of PRB technology at reaction material selection,pollutant repair mechanism,removal of various pollution components and site installation design,development direction of the PRB technology was prospected.
