摘要
生态卫生 (排水 )系统发展的核心思想是要使水资源和营养物质在人类社会和经济发展中以闭合循环的方式运行 ;要以安全、经济、可靠的方法来完成这一闭合循环 ,以达到提高用水效率 ,保护和节约使用有限水资源 ,实现可持续发展的目的。实践已初步证明 ,生态卫生 (排水 )系统在理论上是有依据的 ,技术上是可行的 ,经济上也是合理的。但在人口密集的城市地区与传统排水系统的衔接及更新改造等诸多问题还需要做更多研究。介绍了国外生态卫生 (排水 )系统近年发展特征 ,并与我国发展情况进行了比较 ,提出了应采取的对策。
So called ecological sanitary water discharge (ESWD) system aims for a closed circulation of water resource and nutrients in the human social and economical activates. This circulation must be run in safety, economical and reliable conditions for the ultimate target of sustainable development. The concepts related to increase the water utilization and protect the restricted water resource are very noticeable. The feasibility of ESWD has been stated theoretically, technically and economically by practical ways. However, some problems come down to the conjunction of ESWD with the existing sewer system in urban area with high population density are still researchable. In this paper the recent developments of ESWD home and abroad are presented and compared, and our countermeasures are proposed.
