地震后江油市水源水检测结果分析
|
摘要
目的了解地震后江油市生活用水水源的污染状况,为保障生活饮用水卫生安全提供决策依据。方法采用方便抽样方法,采集震后9～25d江油太平镇和三合镇灾民居住点附近的水源水74份进行检测。对14份水质变黑的井水先进行铁和锰检测,再进行全分析。结果抽检水源水总合格率为38.5%,河水合格率为34.4%,井水合格率为57.1%。不合格指标中,大肠菌群、浑浊度占的比重最大。有6份井水中的铁锰超标。结论震后江油太平镇和三合镇的水源水受到较大污染,存在安全隐患,检测结果对灾民安全用水有重要指导意义。
Objective To survey the pollution status of source water in Jiangyou after earthquake and provide evidence to insure drinking water safety.Methods Seventy four source water samples were collected from the resettlement sites in Taiping township and Shanghe Township 9 to 25 days later after the earthquake by simple sampling and then for laboratory detection.The water samples from 14 wells which had become black were detected for Fe and Mn firstly,then for other analysis.Results The overall acceptance rate of source water was 38.5% with 34.4% of river water and 57.1% of well water.The coliform group pollution and high turbidity were the major problems of water quality.Fe and Mn exceeded standard in 6 well water samples.Conclusion The source water in Taiping Township and Shanghe Township after the earthquake was polluted,which was a potential risk for the people's ealth.It is important to conduct source water detection for the people suffered from earthquake.
