摘 要:目的了解2018-2020年山东省聊城市莘县城乡生活饮用水的卫生状况。方法2018-2020年山东省莘县疾控中心随机选择60个监测点,其中农村20个,城镇40个。每年与枯水期和丰水期各检测1次得到360份水样,按照GB/T 5750-2006《生活饮用水卫生标准检验方法》进行检验。结果2018-2020每年检测水样各120份,共水样360份,总不合格率为27.66%。每年不合格率分别为28.68%、27.64%、26.66%,差异无统计学意义(P>0.05);枯水期不合格率为27.78%,丰水期不合格率为31.11%,差异无统计学意义(P>0.05);农村监测水样共120份,总不合格率为53.33%;城镇检测水样共240份,总不合格率为17.50%,城乡差异有统计学意义(P<0.01)。感官性状和一般化学指标农村不合格率为15.00%,城镇不合格率为6.67%,差异无统计学意义(P>0.05);微生物指标农村不合格率为35.83%,城镇不合格率为10.83%,差异有统计学意义(P<0.01);其他非常规氨氮农村不合格率为2.50%,城镇不合格率为0.42%,差异有统计学意义(P<0.05)。结论山东省聊城市莘县居民饮用水不合格率较高,其中农村居民的饮用水不合格率远高于城镇居民,微生物指标尤为严重,将成为下一步重点监管指标。Objective To analyze the sanitation of drinking water in urban and rural areas in Shen county,Liaocheng city,Shandong province,so as to provide a basis for scientific planning of domestic water use,and ensure the safety of drinking water for residents in Shen county.Methods From 2018to 2020,60monitoring sites had been selected by CDC of Shen county randomly,including 20in rural areas and 40in urban areas.360water samples were obtained after testing once a year in dry season and wet season,and they were tested in accordance with the Standard Test Method for Drinking Water Hygiene(GB/T5750-2006).Results From 2018to 2020,120water samples were tested each year,with a total of 360 water samples,and the total failure rate was 27.66%.The annual failure rates were 28.68%,27.64%,and 26.66%,respectively,with no significant difference(P>0.05);The unqualified rate in the dry season was 27.78%,and it in the wet season was 31.11%,the difference was not statistically significant(P>0.05);120rural water samples were monitored,with a total failure rate of 53.33%,and 240urban water samples were tested,with a total failure rate of 17.50%,and the difference between urban and rural areas was statistically significant(P<0.01).The unqualified rate of sensory traits and general chemical indicators was 15.00%in rural areas and 6.67%in urban areas,and the difference was not statistically significant(P>0.05);the unqualified rate of microbial indicators in rural areas was 35.83%,and the unqualified rate in urban areas was 10.83%,and the difference was statistically significant(P<0.01);the unqualified rate of other unconventional ammonia nitrogen was 2.50%in rural areas and 0.42%in urban areas,and the difference was statistically significant(P<0.05).Conclusion The unqualified rate of residential drinking water in Shen county of Liaocheng city,Shandong provoince is relatively high,and the unqualified rate of drinking water for rural residents is much higher than that of urban residents.Microbial indicators are particularly serious which will b
