Abstract: In order to promote utilization of reclaimed water resources and improve level of utilization and configuration of reclaimed water resources, a framework for classified treatment and refined configuration of reclaimed water was proposed, which included market research on reclaimed water users, comprehensive evaluation of reclaimed water quality, determination of classified treatment technologies, and formulation of refined configuration plans．An analysis was conducted using Suqian City, Jiangsu Province as an example．Based on utilization needs of reclaimed water users in central urban area of Suqian City and investigation results of effluent quality of sewage treatment plants, a classified treatment technology for reclaimed water that met actual situation of Suqian City was proposed according to utilization pathways of industrial water, urban miscellaneous use, landscape environment, and irrigation water．A refined configuration plan for typical sewage treatment plants was developed．Research results could provide support for pilot work of promoting allocation of reclaimed water resources in Suqian City, and have certain reference significance for allocation of reclaimed water resources in other cities in China．
