Water resource is crucial for Xinjiang arid area. Both water quality and water quantity are important for the development of local development. To promote novel usable water source and improve water utilization efficiency on the basis of water quality assurance is the key point for solution of agricultural water issue. This research project aims at providing a feasible technical tool of groundwater bank, which is suitable for water recycle and security in arid area, by utilizing the reclaimed water from urban sewage treatment plant. Based on field work and lab scale comparative experiment, this project is focused on selection of groundwater bank mode for arid area through the study of arid vadose zone with its soil and microbial property, the hydraulic characteristics and pollutant removal efficiency, and related indicators for water security, health and ecological risk analysis via modeling of groundwater bank and identifying the controlling factors. This research will contribute for the understanding of groundwater bank technical tool and provide the fundamental for the future field application in Xinjiang arid area.
