摘　　要：介绍微滤-反渗透"双膜法"在北京经济技术开发区园区污水再生回用中的应用实践,产水规模为60000t/d,相关的工程项目已被列入《2012年国家重点环境保护实用技术示范工程名录》.项目运行结果表明,"双膜法"技术可靠,运行稳定,再生水水质高于国家规范《城市污水再生利用分类》(GB/T18919—2002)及相应分类再生水水质指标,水质合格率达到100%,水价低于开发区工业自来水水价.项目的实施有效缓解了开发区用水紧张问题,保护了开发区及周边地区的生态环境,同时为今后城市园区污水再生回用的研究和应用提供了参考和借鉴.The application of micro filtration-reverse osmosis dual membrane system in wastewater reclamation and reuse in Beijing Economic Technological Development Area （BDA） urban park is described in this paper. This wastewater reclamation and reuse project has a scale of 60 000 t/d, and is listed into the ＂2012 State Key Environmental Protection Practical Technology Demonstration Project Catalog＂. Operation results show that the dual membrane system has the advantages of reliable technique and stable operation, and the product water quality is higher than ＂The Reuse of Urban Recycling Water Classified Standard （GB/T 18919--2002）＂. The product water quality 100~ meets the specified requirement and the water producing cost in this project is superiority comparing to the tap water price in BDA. The project is an effective approach to alleviate water shortage in BDA and protects the ecological environment of BDA and its surrounding area. This project also provides reference for the future study and application on urban park wastewater reclamation and reuse.
