摘要
目的了解坊子区农村饮水的卫生状况。方法按随机抽样原则,于2010年4～5月份,对本区农村集中式供水工程供应的饮水进行卫生学调查和水质检测。结果本区农村饮水以地下水为主,深井水占94.17%。全区完全处理的仅占5.00%,无消毒设施的占95.0%;抽检240份水样,检测总合格率为44.17%;出厂水和末梢水合格率分别为50.83%和37.50%;微生物和硝酸盐超标较为严重,菌落总数、总大肠菌群和硝酸盐(以氮计),超标率分别为19.58%、20.00%和12.08%。结论本区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 In April and May of 2010,the safety engineering project in rural areas was investigated for its general situation and water quality was also tested by sampling.Results Drinking water in rural areas mainly came from underground water,which deep ground water occupied 94.17%,engineering water treated completely only occupied 5.00%,no sterilized equipments accounted for 95.00%.Among 240 water samples tested,the total proportion of qualified water were 44.17%.The qualified rate for outgoing water and terminal water was 50.83% and 37.50%;exceeding rates of the total number of colonies,total coliform and nitrates were 19.58%,20.00% and 12.08%.The contents of micro-organisms and nitrates exceeded the norms severely.Conclusion The rate of qualified water in rural area is low with hidden safety trouble.
