摘要
[目的]全面了解各类供水的水质卫生状况,找出提高水质的办法。[方法]对枣庄市2003～2008年生活饮用水供水单位及提供的水样检测资料进行分析。[结果]2003～2008年合计检测生活饮用水水样2304份,合格率为50.13%。水样合格率,城市集中式供水为53.67%,二次供水为53.01%,小型农村集中式供水为44.56%(P<0.05);丰水期为53.39%,枯水期为46.88%(P<0.01);水源水为56.55%,出厂水为53.95%,末梢水为48.45%(P<0.05)。检测项目中,感官指标、细菌学指标、化学指标、毒理学指标的合格率分别为96.05%、75.56%、52.86%、85.16%;不合格的项目主要是余氯、大肠菌群、总硬度、硫酸盐,合格率分别为79.04%、78.56%、86.91%、54.04%、66.93%。[结论]枣庄市生活饮用水总体合格率较低,影响合格率的主要因素是水源水总硬度、硫酸盐含量偏高,小型农村集中式供水微生物污染较严重,缺乏水质消毒设施。
[Objective]A comprehensive understanding of various types of water quality health situation,identify ways to improve water quality.[Methods]Pairs of Zaozhuang City from 2003 to 2008 units and the provision of drinking water monitoring data of water samples for analysis.[Results]2003-2008 Total testing drinking water samples were 2 304,a pass rate of 50.13%.Water samples pass rate,urban centralized water supply 53.67%,53.01% of secondary water supply,small-scale rural centralized water supply 44.56%（P〈0.05）;wet period is 53.39%,the dry season to 46.88%（P〈0.01）; source water as 56.55%,53.95% water factory,peripheral water 48.45%（P〈0.05）.Test items,the sensory index,bacteriological indicators,chemical indicators,toxicology target passing rates were 96.05%,75.56%,52.86%,85.16%;failed mainly chlorine,coli form bacteria,total hardness,sulfate,pass rates were 79.04%,78.56%,86.91%,54.04%,66.93%.[Conclusion]Zaozhuang City,the overall pass rate of drinking low,affecting the qualification rate of the major factors raw water total hardness,sulphate content of the high concentration of small-scale rural water supply more serious microbial contamination,the lack of water disinfection facilities.
