Accumulation of Ammonia via Electrodeionization Barrier for the Groundwater Denitrification

摘要：

　　The reformative EDI(electrodeionization)technology was shown to be a useful tool as a newly designed permeable reactive barrier(PRB)system in this study.In the PRB,ion exchange resins was employed as adsorption and biological denitrification media under the action of electric field,which can break water forming dissolved oxygen and H+and OH-ions simultaneously.Ions like NH4 t can be accumulated and then oxidized to NO 3 in the concentrated compartment,and the NO-3 produced together with NH4 t could be biologically de-nitrificated.For obtaining a high standard effluent,the multistage operation of the PRB device was adopted,satisfactory accumulation and denirification performance were presented.The results show a promising application prospect of the system in treating groundwater pollution.
