高铁酸盐是一种非氯的新型饮水消毒剂,它利用六价铁还原到三价铁时,放出新生氧,氧化破坏细胞的酶系统,使细菌死亡。所以,杀菌效力高。细菌杀灭率在99.95—99.99％间,经实验室10次以上试验证明,水源水中细菌总数如不超过20～30万个/毫升时,用6毫克/升的高铁酸盐在30分钟内基本杀灭。残存细菌量<100个/毫升,达到我国饮用水质标准。而且高铁酸盐适应pH范围比氯制剂广, Ferrate is a new type of non-chlorine drinking water disinfectant. When it is reduced to ferric iron by hexavalent iron, it releases new oxygen and oxidizes the cell’s enzymatic system, killing bacteria. Therefore, the bactericidal effect is high. Bacterial killing rate was between 99.95-99.99%. More than 10 experiments in the laboratory showed that when the total number of bacteria in the source water does not exceed 200,000-300,000/ml, 6 mg/l of ferrate is used within 30 minutes. Kill. The residual bacteria amount is less than 100/ml, reaching the standard of drinking water quality in China. Moreover, ferrate has a wider pH range than chlorine formulations.
