潍坊市农村饮水卫生现况调查

Investigation on Hygiene Status of Drinking Water in Rural Areas of Weifang City

目的了解潍坊市农村饮水的卫生状况。方法依据《生活饮用水卫生标准》随机抽取农村饮水,采用调查表法对每个监测点的水源类型、供水方式、水处理方式、消毒情况进行卫生学调查和水质检测。结果该市农村饮水以地下水为主,深井水占81.82%(153/187)。经完全消毒处理的水源仅占3.21%(6/187),无消毒设施的占98.40%(184/187);抽检的374份水样,检测总合格率为44.92%;出厂水和末梢水合格率分别为48.13%和45.99%;主要超标项目是菌落总数、总大肠菌群和硝酸盐氮,超标率分别为31.18%、14.44%和11.50%。结论该市农村饮水水质检测合格率较低,农民饮水存在安全隐患。

Objective To find out the hygiene status of drinking water in rural areas of Weifang city and make a safety engineering plan for drinking water.Methods Based on the relative hygiene standards,the safety engineering project in rural areas was investigated for its general situation and water quality was also tested by sampling in April and May 2009.Results Drinking water in rural areas mainly came from underground water,which deep well water occupied for 81.82%（153/187）,completely disinfected engineering water only occupied for 3.21%（6/187）,the water supply engineering without sterilized equipment accounted for 98.40%（184/187）.Among 374 tested water samples,the total qualified rate was 44.92%.The qualified rates for outgoing water and terminal water were 48.13% and 45.99%.The exceeding rates of nitrates,the total number of colonies and total coliform group were 11.50%,31.18% and 14.44%,respectively,it showed that the contents of microorganisms and nitrates exceeded the national standards seriously.Conclusion The qualified rate of water in rural area is low with hidden safety trouble.
