Abstract

iii  Based on the analysis of the relationship between water supply and water demand, put forward the SD strategy for urban water resource utilization as well as the construction of Water-saving City. City construction and industrial distribution should consider the carrying capacity of urban water resources. Improvement of urban water saving depends on reform of water price system and market.  Based on the analysis of the concept and contents of water culture, put forward the principles of construction and repair of urban water culture. Ecological restoration and water landscape restoration should coordinate with urban water culture.  Based on the analysis of the regulation mechanism of water market and management, put forward the direction and contents of the reform of urban water market and management for the SD of SMSCs.  Based on the integrated analysis of the SD of urban water management of SMSCs, put forward two models of circular economy – small and large scope recycling of urban water, and discussed the relevant practical case studies. MBR technology has been introduced in the case study of the wastewater treatment and recycling system of the DJD Hotel (small scope recycling of urban water); SBR technology has been introduced in case study of the wastewater treatment and recycling system of the Huludao City (large scope recycling of urban water).
