目的为掌握甘肃省庆阳市农村饮用水水质卫生现状及其变化规律,为有关部门制定防病改水政策提供科学依据。方法 2015年对全市农村饮用水设置监测点进行卫生现状调查并采样,按照国家《生活饮用水标准检验方法》GB/T 5750-2006和《生活饮用水卫生标准》GB 5749-2006进行检测评价。结果全年检测水样508份,合格329份,总合格率64.8%;其中,微生物指标超标严重,细菌总数、总大肠菌群合格率分别为67.5%、89.8%,理化指标氯化物等6项超标;水质合格率较低为庆阳市北部县区;丰水期合格率(73.2%)高于枯水期(56.3%),两者比较差异有统计学意义(χ2=15.95,P<0.05)。结论庆阳市农村饮用水安全问题较为严重,应加强饮用水监测,确保广大农村居民的饮用水安全。
Objective To understand the present status of hygienic drinking water quality and its variation in rural areas in Qingyang, Gansu Province, and to provide a scientific basis for the relevant departments to formulate the disease prevention and water improvement policies. Methods In 2015, the monitoring points of drinking water in rural areas in the whole city were surveyed and sampled. According to the national standard of drinking water test GB / T 5750-2006 and the standard of drinking water health standard GB 5749-2006. Results A total of 508 water samples were obtained in a year, with a pass rate of 329 and a total pass rate of 64.8%. Among them, the indicators of microorganisms exceeded the standard, the total number of bacteria and the total coliform bacteria passing rate were 67.5% and 89.8% (73.2%) in wet season was higher than that in dry season (56.3%), the difference between the two was statistically significant (χ2 = 15.95, P <0.05). Conclusion The problem of drinking water safety in rural areas of Qingyang City is more serious. Drinking water monitoring should be strengthened to ensure the drinking water safety of the majority of rural residents.
