结合城市供水2000年发展规划的编制,对我国部分大、中城市的供水水质进行了调查,有效资料实收面约占全国建制市总供水量的42～47%。根据资料汇总分析表明,这些城市的水质指标均符合国家生活饮用水卫生标准;但也发现某些城市在输水过程中有在水质不稳定问题,有待深入研究解决。 Combined with the preparation of the 2000 urban water supply development plan, the water quality of some large and medium-sized cities in China was investigated. The effective data collection area accounted for approximately 42 to 47% of the total water supply of the national establishment system. According to the data summary analysis, the water quality indicators of these cities are all in line with the national sanitary standards for drinking water; however, it has also been found that some cities have problems in water quality instability during the water delivery process, which needs further study and resolution.
