生态卫生(排水)系统国内外发展比较 总被引:7,自引:0,他引:7
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。 相似文献

With the application of system dynamics, a dynamic nonlinear model reflecting the relationship between decentralised water use and reclaimed water supply and demand has been established. Through a system analysis, the model has been applied to a small residential district to predict and analyse the situation of future use of fresh water, demand and supply of re-used water, and treatment scale of reclaimed water. It is illustrated in this paper that wastewater decentralised treatment and re-use can decrease the consumption of fresh water without lowering the standard of living water for the district residents. On this basis, a rational scale and construction time of the decentralised sanitation and re-use system have been determined. Also, the paper predicts the influencing factors of the increasing water cost and changes in consumers' acceptability to re-use water in the decentralised sanitation and re-use system. 相似文献

Sustainable sanitation and water in small urban centres. 总被引:1,自引:0,他引:1

The objective of this paper is to review the global trends in urbanization with respect to availability of adequate sanitation and water supply services. Urbanization is unrelenting and rapid increase in the urban population in the less developed countries is of major global concern regarding this topic of sustainable sanitation and water. Most global urban growth is in the smaller cities and in the developing world. Half the urban developing world lacks adequate water and sanitation. Global urban access to waterborne sanitation is not affordable and thus is not a realistic option so alternative approaches are necessary. The treatment of drinking water cannot be a substitute for sanitation. In order to achieve sustainable sanitation, a change in attitude about human excreta and use of water is required. Essential features of a sustainable sanitation system are: containment, sanitisation and recycling. To improve water supply, we need to improve management practices, use full-cost pricing, introduce watershed approaches to protection and provide improved sanitation. Small urban initiatives need to go beyond the traditional sectors and new initiatives are required like on-site urban ecostations, source-separation of urine and faeces, decentralised greywater treatment and integration of sanitation into the cost of housing. 相似文献
