摘　　要：适宜山丘区分散供水的消毒技术模式尚未系统建立。为进一步保障分散式供水水质,按照前置净水与紫外线消毒相结合的原则开发桶式紫外线消毒装置。桶式紫外线消毒装置以低压高强度的紫外灯为核心,以前置PP棉过滤器和活性炭过滤器为水质保障单元,并在华北地区某山丘区分散户进行安装应用。结果表明,桶式紫外线消毒效果可靠,原水总大肠菌群90 CFU/100 m L情况下,紫外灯开启5 min/h可有效保障出水微生物安全性,年运行成本仅110.56元,运行维护简便,具有广阔的应用前景。At present, the mode of appropriate disinfection technology in decentralized water supply engineering has not yet been established. To improve water quality of decentralized water supply systems, combined with pre-water treatment and ultraviolet disinfection, based on low -pressure and high intensity ultraviolet and water quality security unit （ PP cotton filter and activated carbon filter）, barrel-type uhraviolet disinfection device is developed in this paper. The actual application effect of barrel-type uhraviolet disinfection device is studied in a house- hold water supply system of northern area. Results show that the barrel-type ultraviolet disinfection device can guarantee the water microbial safety effectively. The ultraviolet lamp radiated 5 min/h can kill 90 CFU/100 mL total coliforms in raw water. The barrel-type ultraviolet disinfection device has a broad application prospect with simpIe maintenance and low annual running cost.
