Based on the analysis of hydrogeological conditions and geological formations in the Huangjia riverside well field, Shenyang City, the redox zonation during water infiltration process was integrally studied on the basis of in-situ monitoring together with indoor experiments. Our study reveal that regular patterns of the redox zonation along the river water infiltration do exist in the riverbed sediments of Liaohe River.Successive arrangements of O2-NO3- mixed reduction zone, mangne-oxide reduction zone and iron-oxide reduction zone are found embedded in the depth of 0~20cm, 20~80cm, 80~90cm in the riverbed. It is implied that dissolved organic carbon (DOC) from the river water could not provide enough electrons as the reduction oxidants. DOC in river and the dissolved sedimentary organic carbon (SOC) involve in the redox reaction as carbon sources together. © 2016, Editorial Board of China Environmental Science. All right reserved.
