摘　　要：介绍了适宜农村供水工程采用的次氯酸钙片剂及比流式自动变量投加设备、次氯酸钙饼剂及简易浸泡式自动变量投加装置。针对2种不同固体形态的次氯酸钙消毒剂及其加药装置,分别阐述了其技术特点及工作原理,分析了其工程应用情况及运行效果,通过理论计算、试点工程观测2种方式测算了其运行成本。结果表明2种装置运行稳定,消毒效果达标,成本低,在农村供水工程中具有较大推广价值。其中比流式次氯酸钙自动变量投加设备适合管理条件较好的适度规模农村集中供水工程;简易浸泡式次氯酸钙自动变量投加装置适合管理条件相对较差的农村小型集中或分散供水工程。Two kinds of calcium hypoehlorite disinfectant and dosing devices are introduced in this paper, which are respectively calci- um hypochlorite tablets and fixed-ratio automatic variable dosing device, calcium hypochlorite cakes and simple soaked variable dosing device. Both of the above-mentioned solid forms of calcium hypochlorite disinfectant and dosing devices are described thoroughly, in- cluding their technical characteristics, working principles, engineering applications and operating results. Besides, their operating costs are measured by theoretical calculations and pilot project observations separately. The results show that the two kinds of disin- fection devices run stable with qualified disinfection results and low costs, so they are both worth popularizing in rural water supply projects. The fixed-ratio automatic variable dosing device is suitable for appropriate scale central projects which have good manage- ment conditions, as the simple soaked variable dosing device was suitable for small scale central and dispersed projects which had poor management conditions.
