【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。更多还原

【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.更多还原
