摘　　要：我们于1995年3月～4月调查了武汉市高位铁皮水箱的供水质量。结果表明:高层住宅水箱近年虽曾清洗消毒,但高层用户龙头水及水箱水中游离性全氯未达标比例较大,分别为73.3％和66.7％。个另U底层住户水样中铁超标。高位水箱水样中细菌总数超标比例为20％。反映了高层住宅二次供水中在水的输送、贮存过程中有二次污染存在。经水样监测指标相关性和灰色关联性分析,认为游离性余氯可作为常规监测高层住宅二次供水质量的代表性指标。季节性因素对高层住宅二次供水质量的可能影响有待进一步研究。The water quality of iron sheet cistern in perch was investigated in Wuhan during the period of March through April 1995. The results showed the cisterns of investigation high buildings have been cleaned up and disinfected in the recent years,however,the ratios of samples that the concentrations of Free Residual Chlorine were exceeded the limits were higher,about 73.3% for the faucet and 66.7% for the cistern,respectively. Few of samples collected from the taps of the lowest households for iron concentration exceeded the limit. The data showed that there was secondary pollution in the course of transportation and reserve of water. After the relative analysis by statistics,it was thought that Free Residual Chlorine to be a representative water characteristic for routine monitoring of water quality of the high building. It will need further study on the seasonal influence factor on the secondary water supply quality of high building.
