为系统了解和掌握吴忠市区降氟改水工程的使用状况及水氟回升情况,于2011年3月对该地区19个乡、镇(场)的所有已建降氟改水工程的工程运转现状和水氟含量进行了调查。采集每座在用降氟工程出厂水和管网末梢水各1件。采用离子选择电极法测定水氟含量。每座工程水氟含量以2件水样水氟
In order to understand and grasp the use status of fluoridation and water diversion project in Wuzhong urban area and the situation of water fluorine recovery in the system, in March 2011, all the projects of water and fluoride removal and water diversion works in 19 townships and towns (farms) in the area were operated Status quo and water fluorine content were investigated. Collecting each factory in the use of fluorine-containing water plant and pipe network water one each. Determination of water fluorine content by ion selective electrode method. Each project water content of fluorine to 2 pieces of water fluoride
