Analysis on the present running status of water-improving project in Anda city,Heilongjiang province in 2008

目的 了解2008年黑龙江省安达市降氟改水工程分布、运行现状和存在问题.方法 对安达市全部降氟改水工程进行全球定位系统（GPS）定位及工程运行和管理现状逐项调查.结果 共调查降氟改水工程317处,由于改水工程超期使用、管理不善,停用工程51处,占16.09%,报废工程77处,占24.29%;供水设备未配套、供水管网未铺造成工程闲置83处,占26.18%;目前运行的改水工程106处,占33.44%,水氟达标的工程只有46处,占14.51%,受益人口数3.6万人.结论 安达市降氟改水工程运行状况令人十分担忧,报废、停用、闲置现象严重,急需改进.

Objective To understand the running status and distribution of water-improving pmjects in Anda city.Methods The running and management of the water-improving projects were investigated and located the position by Global Positioning Systerm（GPS）in Anda city.Results Among 317 water-improving projects,16.09%were either long-term projects or in poor management or had already stopped usage,77 projeets were broken,accounting for 24.29%;all inadequate supply of equipment and pipeline,83 projects had never been started,accounting for 26.18%;now,106 projects were running,accounting for 33.44%.In only 46 projects,the water fluoride concentration was lower than 1.00 mg/L,accounting for 14.51%,as a result 36 thousand people benefited.Conclusions The running status of water-improving projects was unacceptable,most of them stopped running and endemic fluorosis control was still severe in Anda city.
