摘要
西南峰丛区居民主要采用溶井、水柜与水窖三种模式进行分散式供水,其水源分别来自地下河、岩溶泉及雨水。水柜供水适用于有使用价值的泉水出露的峰丛山区,溶井供水主要适用于有竖井的峰丛洼地底部及溶丘谷地边缘,水窖供水多用于地势较高、地表垂向岩溶极为发育、仅有雨水可供利用的峰丛山区。在大量调查与实际工程基础上,本文分别对三种供水模式的设计思路、设计参数与施工中的注意事项进行了详细论述,并给出了分散供水模式的设计示意图。分散供水目前存在的主要问题是选址布局不合理、设计与施工不科学以及水质安全得不到保障,对分散供水工程进行储水、供水与水处理一体化优化设计是保障水质安全的可靠手段。
There are three major dispersal water supply patterns in karst peak-cluster area in southwest China, namely water cistern, water tank and natural well with the source of water from rainfall, spring and subterranean fiver separately. Water cistern is fit for the peak-cluster area with abundant karst spring water supply; natural well is fit for the bottom of peak-cluster area and the edge of karst valley with subterranean stream and shaft; water tank is used in the peak-cluster area without other water supply except for rainwater. Based on a great deal of investigation and factual engineering, the design thinking, design parameter and items for attention in construction for the three water supply patterns are discussed in detail, and the sketch map for designing dispersal water supply pattern is put forth at the same time. The major problems in dispersal water supply at present are irrational locating, unscientific design and construction, and the security of water quality not able to be guaranteed. To carry out integrated optimizing design in the process of water storage, supply and treatment is reliable measures to guarantee water quality.
