摘　　要：1)目的 :报道了研制的一种适合农村水厂特点的经济、实用、简便易操作、高效的臭氧水处理设备。2 )设计思想及技术路线 :农村水厂的消毒设备必须具备作用迅速 ,运行成本低廉 ,同时自动化程度高、易于操作。臭氧水处理器的技术核心是产生高浓度臭氧并有效地掺混于待处理水中 ,根据用水量的变化 ,自动投加到供水主管路中。3)消毒效果 :加标实验表明 ,在臭氧浓度不低于 0 2mg L时 ,3分钟的接触时间足以杀灭水中的细菌和大肠菌群。现场应用实验结果表明 ,在三个村采集的 2 0个水样细菌总数和大肠菌群均符合生活饮用水水质卫生规范 ,说明臭氧水处理器对大肠菌群和细菌的杀灭作用可靠。 4)讨论及结论 :本研究的创新点在于研制出新型掺混技术 ,效果可靠、作用迅速、程控自动操作、设备自身和运行成本低廉。To design an ozone disinfection apparatus which is inexpensive and to practical for small drinking water supply system in rural areas. And test its effectiveness. Designed apparatus must be rapid, low cost, high automatic and easy for operation. The key technologies are to create ozone of high concentration and to mix it with water very well, and add it into main water pipe automatically.The results showed: In laboratory,at the condition of ozone of 0 2mg/l for 3 minutes, all germs and bacteria coli were killed. In the field study, the water samples from three villages met the standard for drinking water very well. The conclusions: The apparatus reached the design requirement. An innovative part of the study is that we have improved a device for mixture of ozone with water. The laboratory and field study have proved the apparatus is low cost, high effectiveness, and easy to operate u. It is very useful for small drinking water supply system in rural areas.
