分质供水模式的发展研究

文章详细介绍了国内外的分质供水概念,对日本、美国及国内的分质供水模式发展进行了调研分析,指出国内外的分质供水系统在概念上有着较大差别。发达国家城市供水是以利用优良水源,全面提高供水水质为主导思想。在上世纪九十年代的国内供水,由于水源水质受到严重污染,在大城市出现了利用自来水深加工形成小区直饮水供水形式,形成了"饮"用水分质供水系统。随着国内城市饮用水水源水质及制水工艺提高,供水水质改善,小区直饮水将慢慢退出市场,城市供水模式以全面提高主供水系统水质为主导发展方向。

Study on Development of Quality of Water Supply Model

The paper described the concept of quality of water supply at home and abroad,the development of Japan,the United States and the domestic water supply by mode analysis and research,pointed out that domestic and international quality of water supply system had a larger difference in concept.Developed countries,urban water supply is based on the use of fine water,and comprehensively improve the quality of water for the dominant ideology.In the nineties of the last century,the domestic water supply,water quality is seriously contaminated,in big cities use water deep processing of the formation of the district to direct drinking water supply form,forming a ＂drink＂ the water quality of the water supply system.Improve as the domestic urban drinking water sources and water technology,water supply,water quality improvement,residential drinking water straight out of the market slowly,urban water supply model to comprehensively improve the development direction of the main water supply system water quality led.
