摘要
目的掌握张家口市降氟改水工程运行情况及水氟含量，为饮水型氟中毒防治提供科学依据。方法在张家口市地方性氟中毒病区，选择截至2010年修建的降氟改水工程，调查改水工程的运转情况、资金来源情况等。在每处正常使用的改水工程处，采集1份水源水和2份末梢水，采用生活饮用水卫生标准检验方法（GB／T5750．5—2006）测定水氟。结果共调查386处降氟改水工程，其中正常使用工程310处，占80．31％；间歇使用工程6处，占1．55％；报废工程70处，占18．14％。对316处降氟改水工程进行了水氟调查，其中水氟合格工程175处，占55．38％；水氟超标工程141处，占44．62％。调查的386处降氟改水工程中，共投资2186．82万元，其中国家、集体、个人分别投资1007．80万元、621．04万元、557．98万元，分别占总投资的46．09％、28．40％、25．51％。结论张家口市降氟改水工程运行现状令人十分担忧，应进一步加大病区改水力度，坚持可持续降氟改水防治策略。
Objective To master current operating situation of water-defluoridation-project and the level of fluoride in drinking water of Zhangjiakou city and provide a scientific basis for prevention and control of the disease. Methods Itemized survey of current operating situation of water defluoridation projects built in 2010 and before, and the source of fund situation in Zhangjiakou city was carried out. One source water and 2 terminal water samples of the projects in use were collected, respectively. Water fluoride were determined by ＂Sanitary Standard for Drinking Water Testing Method＂ （GB/T 5750.5-2006）. Results A total of 386 water improvement projects to reduce fluoride were investigated, 310 in good operation, accounting for 80.31%; 6 in intermittent use, accounting for 1.55%; 70 out of use, accounting for 18.14%. Water fluoride was surveyed in 316 water improvement projects to reduce fluoride, 175 of the projects provided water with normal fluoride, accounting for 55.38% ; 141 of the projects provided water with fluoride exceeded the standard, accounting for 44.62%. The total investment of 386 water defluoridation projects was 21.8682 million yuan, the investment of the state, the collective and the individual were 10.0780 million yuan, 6.2104 million yuan and 5.5798 million yuan, accounted for 46.09%, 28.40%, 25.51%, respectively. Conclusions The current situation of the projects is very worrying in Zhangjiakou city. Further instensify the water improvement project in diseased areas, insist on sustainable water defluoridation strategy.
