对新疆维吾尔自治区农村改水工程中广泛应用的新技术从基本原理、运用条件和优点等方面进行总结 .获国家发明专利的曼苏尔井是一种新型免维护自流井 ,具有低投入、长寿命、高效益等优点 ;经过改进和优化的深井手动泵特别适合于居住分散、缺水少电的农牧区 ;降氟综合技术能够有效地降低饮用水的氟含量 ;电渗析法则可变苦咸水为甘泉 .

New techniques adopted in water supply projects in the countryside of Xinjiang Autonomous Region have been summarized from the basic principles, application conditions and advantages concerned. The Mansul Well that holds a patent is an artesian well with low investment but high benefit and a long service life without special maintenance. Through improvement, a new type of hand pump used for deep well is suitable for the regions with scattered residents, but without surface water and electric energy. The synthetic fluoride reducing technology can reduce the contents of fluoride in drinking water effectively. The electric dialysis method could turn bitter water into sweet spring water. Some new physical reconnoiter techniques, such as the measurement of geotectonic resistivity, are powerful safeguard in the selection of good water sources.
