Zhu Jingtao1,Han Zhiyong2,Wei Xiangjun3,Han Ruihong4(1.Gansu Research Institute of Environmental Science,Lanzhou 730010,China;2.College of Petrochemical Technology,Lanzhou Univ.of Tech.,Lanzhou 730050,China;3.College of Civil Engineering,Lanzhou Univ.of Tech.Lanzhou 730050,China;4.Management Bureau of Xiashan Reservoir,Weifang 261300,China)  
The permeable reactive barrier is a new and high efficient technology at the field of groundwater in situ treatment,and its mechanism to remove the pollutants is chemical reaction and biodegradation between the pollutants and the reactive materials which filled in the barrier aimed at different pollutants.The structure,type and work mechanism of the permeable reactive barrier technology are introduced systemically in this paper,and the install process is also discussed generally.At the same time,some problems are brought forward and analyzed,and the developing prospect is expected.It will provide references for the appli cation and generalization to use at domestic.
