摘　　要：以强调回收污水中资源与能源的可持续污水处理理念,使得分散式污水处理技术再次显出勃勃生机。污水分散式处理特别适合于那些远离城市下水管网的住宅小区、别墅、乡镇住宅等场合,它们能从源头控制污染、回收资源与能源。因此,分散式是一种与集中式并行的污水处理方式,是集中式污水处理的有效补充。以美国为例,介绍了分散式污水处理的发展历史、应用现状和未来发展趋势。The concept of sustainable wastewater treatment emphasizing recoveries of energy and resources makes the original decentralized wastewater treatment renewed. The decentralized wastewater treatment systems are especially suitable for housing plots, single houses and farm houses which are far from municipal sewer systems, and they can control water pollution and recover energy and resources from wastewater at sources. Therefore, the decentralized wastewater treatment coexists with centralized systems and becomes a supplement of centralized systems. The development history, current application status and potential future of decentralized wastewater treatment in United States are introduced.
