目的全面了解泉州市政集中式供水水质情况,为保障居民饮水安全提供参考。方法对2011—2014年64份市政水厂出厂水、管网水进行102项的水质全分析。结果64份水样合格率为78.1%。48份出厂水合格率79.2%,影响合格率主要为:氯酸盐95.8%、铝95.8%、亚氯酸盐97.9%、三氯乙醛97.9%、锰97.9%、总大肠菌群97.9%、余氯97.9%、浑浊度97.9%;16份管网水合格率75.0%,影响合格率主要为:三氯乙醛87.5%、铝93.8%、余氯93.8%。不同类型、不同水期、不同年度间合格率变化均无统计学意义。结论应加强水源水保护,改进水厂制水工艺,加强日常监督监测,以提高泉州市饮用水卫生安全。
Objective To comprehensively understand the centralized water quality of municipal water supply in Quanzhou and provide reference for the safety of residents drinking water. Methods A total of 102 water quality analyzes of 64 municipal waterworks from 2011 to 2014 were carried out. Results The qualified rate of 64 water samples was 78.1%. 48 qualified batches of 79.2%, the main factors affecting pass rate are: chlorate 95.8%, aluminum 95.8%, chlorite 97.9%, trichloroacetal 97.9%, manganese 97.9%, total coliform 97.9% 97.9% of residual chlorine and 97.9% of turbidity. The qualified rate of water in 16 pipe networks is 75.0%. The main qualified rate is 87.5% of chloral hydrate, 93.8% of aluminum and 93.8% of residual chlorine. Different types, different water periods, the passing rate between different years were not statistically significant. Conclusion Water source protection should be strengthened to improve the water technology of waterworks and to strengthen the daily supervision and monitoring so as to improve the hygiene and safety of drinking water in Quanzhou.
