校园小区中水回用的经济技术分析

中水回用是解决中国城市水短缺和水污染问题的重要手段,对小区而言具有实践可行、技术成熟、综合效益高等优势。文章在分析城市中水回用实践存在的障碍基础上,提出化整为零的污水处理回用方式,阐述了小区中水回用系统建设的必要性和可行性。文章结合校园小区的给排水状况、校园小区的中水处理工艺,通过校园小区的中水处理系统的经济技术分析、中水供水系统的经济技术分析、中水系统综合效益的分析提出建议,认为随着膜生产技术的发展,MBR法应是小区中水回用工艺的首选。

Technical and Economic Analysis on Reclaimed Water Reuse in University Community

Reclaimed water reuse is a very important method to solve the shortage and pollution of water in Chinese cities.It has the advantages of feasible,mature and high market potential.Based on analysis of obstacles which hold back the practice of reclaimed water reuse in cities,this article puts forward reclaimed water reuse in community and analyzes the necessity and possibility of this application.With the combination of water supply and drainage as well as reclaimed water treatment process,some suggestions are put forward through research of reclaimed water treatment and supply system from economic and technical views,analyses of comprehensive benefits of reclaimed water system.It is concluded that with the development of membrane technology,MBR method is the primary choice for reclaimed water reuse in community.
