河南省降氟改水工程管理模式抽样调查及效果评价

Sampling investigation of the management pattern of defluoridation projects in Henan Province and the effect of different management patterns

目的了解河南省降氟改水工程运行现状,探索改水工程的高效管理模式。方法采取以县为单位整群抽样,对安阳、濮阳、焦作3个市的安阳县、清丰县、武陟县3个县的降氟改水工程全部进行调查。结果共调查442处降氟改水工程,其中正常使用工程327处,占73.98%,间断供水工程20处,占4.52%,停用及报废工程95处,占21.50%。3个县的降氟改水工程中,行政村管理模式、个人承包管理模式和商业化管理模式的正常运行率分别为71.69%、60.50%和92.79%,差异有显著性(P<0.01)。结论商业化管理模式的降氟改水工程发挥的效益最高,经济条件许可的地区应倡导这种管理模式。

Objective To investigate the running status of the projects of defluoriding drinking water and the effect of different management patterns of the projects. Methods Cluster sampling of counties was conducted. All of the defluoridation projects from Anyang County, Qingfeng County and Wuzhi County were seleeter to be investigated. Results Among 442 projects investigated, 327 projects were running normally, aeeouting for 73.98% ; 20 projects working intermittently, accouting for 4. 52% ; 95 projects were out of service, aeeoufing for 21.50%. The projects of 3 counties were re- spectively managed by administrative villages, individual contractors or under a commercial pattern , in which the percent- age of well working projects was 71.69%, 60. 50% and 92. 79% respectively, the differences being signifiuant （ P 〈 0. 01 ） . Conclusion The commercially managing pattern has the best effect of defluofiding improving water and it should be reinforced in the future.
