我国村镇供水处理技术及发展模式探讨

Discussion on water supply technology and developing pattern of villages and small towns in China

通过介绍我国村镇供水工程的现状和特点,表明了我国村镇供水存在着工艺落后、供水安全性差等问题。为保障村镇供水水质,详细介绍了各种不同水源,如地下水、地表水和特殊水质水源的处理技术和工艺流程,同时对村镇供水发展模式进行了初步的探讨,提出了村镇分散式、集中式等六种供水模式。同时提出了村镇供水工程应综合考虑水源的选择与保护、净化技术与供水模式,并因地制宜,坚持可持续发展的原则。

The laggard technology and poor safety of water quality are showed by discussing the current state and characteristics of water supply of villages and small towns in China. Different treating methods for several kinds of water sources, such as groundwater, surface water and special water quality sources are introduced detailedly to ensure the quality of water supply. Some suggestions for developing patterns of water supply project are also discussed, and six water supply patterns as decentralized and centralized water supply, etc. for villages are proposed. It is suggested that the selection and protection of water sources, the patterns of water supply and water treatment technology should be considered integrally in the water supply projects. Moreover, the water supply projects for villages and small towns should insist principles of sustainable development and adjust to local conditions,
