目的对郑州市某区2014年生活饮用水检测结果进行分析,以了解水质状况。方法按照《生活饮用水标准检验方法》(GB5750-2006)对辖区内二次供水单位、农村饮用水及自备供水单位的饮用水水质进行检测,按照《生活饮用水卫生标准》(GB5749-2006)进行评价。结果检测314份水样中,总合格率为73.57%(231/314)。二次供水、农村饮用水、自备供水水质合格率分别为82.80%(207/250),56.82%(25/44),45%(9/20)。三种供水类型水质合格率差异有统计学意义(χ2=26.224,P<0.001)。结论辖区内二次供水水质合格率最高,农村饮用水和自备供水合格率较低,水质安全状况有待提高,监管力度有待加强。
Objective To analyze the test results of drinking water in a district of Zhengzhou City in 2014 in order to understand the status of water quality. Methods According to “Standard Test Method for Domestic Drinking Water” (GB5750-2006), drinking water quality of secondary water supply units in rural areas, rural drinking water and self-provided water supply units was tested. According to the standards of Sanitary Standard for Drinking Water (GB5749-2006) ). Results In 314 water samples, the total pass rate was 73.57% (231/314). Secondary water supply, drinking water in rural areas, self-provided water quality pass rates were 82.80% (207/250), 56.82% (25/44), 45% (9/20). There was a statistically significant difference between the three types of water quality (χ2 = 26.224, P <0.001). Conclusion The qualified rate of secondary water supply in the area is the highest, the passing rate of rural drinking water and self-provided water supply is low, the water quality and safety status needs to be improved, and the supervision and control need to be strengthened.
