摘要 针对高海拔地区山区和西北部农村可饮用水源少、集雨饮用水浊度、微生物、重金属等超标的问题,以保护集雨水源地和保障饮水安全为目标,面对水量变化剧烈、水质复杂、建设和运行资金短缺、城镇技术设施条件差等特点,开发了适合小城镇的经济、高效、节能慢沙过滤低成本饮用水净化技术。该技术针对不同群体构建了分散式和集中式两种饮水安全保障模式,保障供水水质满足《生活饮用水卫生标准(GB5749)》的要求,提供技术支撑。也可为地震、洪涝等自然灾害发生时的应急饮用水净化措施提供技术保障。

Abstract Facing the problems of lacking potable water and overproof of microorganism and heavy metals in collected rain water in high altitude and northwest urban area of China, an economic, efficient, energy conservation and low cost water cleansing technique was developed to deal with the reality of dramatically changing of water amount, complicated water quality, shortage of fund of construction and operation and unenlightened technology condition in small town. It has two safeguard styles, distributed and centralized to make sure the water meet the criterion of hygienic standard for drinking water(GB5749). It can provide technical support for emergency water cleansing such as earthquake or flood disaster.

国家实施的“发展小城镇,带动农村经济和社会发展战略”推进了我国城镇一体化进程。面对农村饮用水存在水质较差、水源遭受污染、卫生管理不及时等问题,根据环境保护部下发的《关于印发〈全国典型乡镇饮用水水源地基础环境调查及评估工作方案〉的通知》(环办〔2009〕27号),开展了全国乡镇集中式饮用水水源的调查与评估工作,对水源地的现状进行调查评估工作,针对不同区域、不同类型的饮用水水源地提出环境对策,提高广大人民群众的饮水安全保障水平,特别是在部分偏远、居住极为分散的山区、半山区。……
