摘要
目的掌握泸州市农村集中式供水安全现状,建立本底,查找问题,提出建议,供政府相关部门决策。方法按普查方法以泸州农村集中式供水站作为调查(监测)点,进行采样并实验室检测。结果全市农村109个集中式供水工程的水源主要是水库水,占总数的33.03%;枯水期、丰水期采集水样各为218份;检测合格率枯水期为18.35%、丰水期为23.85%,总合格率为19.95%;不合格指标主要为微生物学指标和感官性状指标。微生物指标中超标最多的是总大肠菌群,占总数的57.34%;其次是耐热大肠菌群,占总数的43.12%;再次是菌落总数,占总数的16.51%;感官性状超标指标中,浑浊度超标的158个,占总数的36.24%。结论泸州农村集中式供水安全性较差,水质合格率低,微生物超标是主因。
Objective To understand the safety of centralized water supply in rural area in Luzhou,provide evidence for the improvement of water supply in the rural area.Methods The water samples were taken from the centralized water supply systems for laboratory detection.Results The source water of 109 centralized water supply systems were mainly taken from reservoirs,accounting for 33.03% of the total source water.Totally 218 water samples were detected in low water period and in high water period respectively with the qualified rates of 18.35% and 23.85%.The overall qualified rate was 19.95%.The unqualified indicators mainly included microbiological indicators and organ sense indicators.The main unqualified microbiological indicators were total coliform（57.34%） and thermoduric coliform（43.12%） and total numbers of colony（16.51%）.The main unqualified organ sense indicator was turbidity（36.24%）.Conclusion The quality of drinking water from centralized water supply systems in rural area of Luzhou is poor,which mainly results from microorganism contamination.
