摘要

Water has long been a confinement factor and is increasingly becoming a major obstacle for local socioeconomic development in Shenzhen, China. Nearly 80% of the city's total water consumption is supplied by the distant water diversion project. The long-term planning for municipal wastewater reclamation and reuse in Shenzhen was completed in 2001 to increase the available water resources and to decrease the pollutants discharged into natural water bodies from sewage disposal system. Parts of the proposed reclaimed water system are now being implemented. The plan was characterized by the whole city's range and integrates sewage treatment with reclaimed water supply. This paper described the background and main parts of the plan. The data of water resource and current water usage pattern of Shenzhen were briefly presented. The items of the plan, such as reclaimed water user and potential demand, reclaimed water supply capacity, reclaimed water system layout, distribution pipelines, treatment process for reclaimed water as well as the cost and economic benefit of the proposed reuse scheme were discussed. Several considerations for making such a plan were also included. The results showed that the capacity of the reclaimed water supply system will reach 22.0x10~4 cubic meters per day in 2005 and 49.0x10~4 cubic meters per day in 2010. At that time, the available amount and quality of the local water will be improved significantly.
