目的了解广西乐业县大石围山区生活饮用水水质现状,为进一步改善水质质量、预防水源性疾病提供科学依据。方法 2011年-2013年共采集枯水期、丰水期水样240份,按照GB/T 5750—2006《生活饮用水标准检验方法》进行监测。结果 2011年-2013年共监测的240份水样中,各项指标的总超标率为70.42%。丰水期和枯水期超标项目之间差异有统计学意义(P<0.05),超标率较高的是微生物指标,枯水期水质比丰水期要好。结论大石围山区生活饮用水安全状况存在隐患,缺乏水源保护意识和有效的消毒措施。居民应改变饮用生水的习惯,加强对水质的消毒和净化;相关部门应加强生活饮用水的监督管理和宣传,减少可控的水源性疾病,保证居民的饮水安全和身体健康。
Objective To understand the status quo of drinking water quality in Dashiwei mountainous area of Leye county in Guangxi province and to provide a scientific basis for further improvement of water quality and prevention of waterborne diseases. Methods A total of 240 water samples from dry season and wet season were collected from 2011 to 2013 and monitored according to GB / T 5750-2006 Standard Test Method for Domestic Drinking Water. Results Among the 240 water samples monitored in 2011-2013, the total over-standard rate of each indicator was 70.42%. The differences between the wet season and the dry season were statistically significant (P <0.05). The higher the standard rate was the microbial index, and the dry season water quality was better than the wet season. Conclusion There are hidden dangers in the drinking water safety status in Dashiwei Mountain area, lack of water conservation awareness and effective disinfection measures. Residents should change the habit of drinking raw water and strengthen the disinfection and purification of water quality. Relevant departments should strengthen supervision and management of drinking water and publicity to reduce controllable water-borne diseases and ensure their drinking water safety and physical health.
