云南山区饮水安全小型集中供水工程设计与探索

Design and Exploration of Small Centralized Water Supply Project for Drinking Water Safety in Yunnan Mountainous Areas

农村饮水工程是广大村民安全用水的重要保障。经过长期的农村饮水工程建设,饮水安全基本得到解决,目前最突出的问题是旱季水源短缺和已建工程运行维护难度大。通过对云南山区禄丰县的实地调查,在总结山区饮水工程状况和特点的基础上,提出旱季水源短缺地区“混合供水”和海拔高差较大地区“分级供水”的供水系统设计模式,为山区饮水安全巩固提升提供可行的建议。

Rural drinking water project is an important guarantee for the safety of water use for the majority of villagers.After a long-term construction of rural drinking water projects,the safety of drinking water has been basically solved.At present,the most prominent problems are the shortage of water resources in dry seasons and the difficulty of operation and maintenance of the existing projects.Based on the field investigation of Lufeng County in Yunnan mountainous area,and on the basis of summarizing the status and characteristics of drinking water projects in the mountainous area,this paper puts forward the system design mode of drinking water projects with“mixed water supply”in water shortage area and“graded water supply”in the area with large elevation difference,so as to provide feasible suggestions for the consolidation and improvement of drinking water safety in the mountainous area.
