使用空气隔离-同轴降膜反应器对饮用水进行电场和放电杀菌,在输入电压10 kV、频率12.5 kHz、处理时间50 s时,细菌总数分别减少了3.77和3.85个数量级.研究结果表明,放电杀菌的能量利用率及杀菌效率均高于电场杀菌.流式细胞仪和荧光电镜检测发现,电场和放电杀菌均对细菌蛋白质造成损伤,且电场处理过的细菌存在可进行损伤修复的亚致死细胞,而放电杀菌则不存在亚致死现象,表明放电杀菌具有较高的杀灭率.杀菌过程中活性自由基检测结果表明电场杀菌技术不会产生自由基等活性物质,相比较而言电场杀菌具有较高的安全性.
Using air isolation-coaxial drop-down reactor, electric field and discharge sterilization of drinking water were carried out, the total number of bacteria decreased by 3.77 and 3.85 orders respectively at the input voltage of 10 kV, the frequency of 12.5 kHz and the treatment time of 50 s.The results showed that, Discharge bactericidal energy utilization and bactericidal efficiency are higher than the electric field sterilization.Flow cytometry and fluorescence microscopy examination found that electric field and discharge sterilization are bacterial protein damage, and electric field-treated bacteria damage can be repaired sub-lethal Cells, while the discharge sterilization without sublethal phenomenon, indicating that the discharge sterilization has a higher killing rate.Visitogenic activity during the sterilization test results show that electric field sterilization technology will not produce free radicals and other active substances, compared with electric field sterilization With high security.
