为了解次氯酸钙对某些肠道致病菌的杀灭作用,在实验室内进行了试验。使用的消毒剂为市售的漂白粉精片,测试菌种为埃尔托弧菌、沙门氏菌及志贺氏菌。试验结果表明,在自来水悬液中(无有机物存在),对于埃尔托弧菌和沙门氏菌,只需含10mg/L有效氯的溶液作用5分钟,或5mg/L溶液作用10分钟,即可将其完全杀灭(定性试验结果,下同);对于志贺氏菌含有效氯20 mg/L溶液作用5分钟,或5mg/L溶 To understand the killing effect of calcium hypochlorite on certain enteric pathogens, experiments were conducted in the laboratory. Disinfectants used are commercially available bleach tablets, tested strains of El Torcos, Salmonella and Shigella. The test results showed that in the tap water suspension (no organic matter), for El Torcos and Salmonella, only containing 10mg / L available chlorine solution for 5 minutes, or 5mg / L solution for 10 minutes, you can Its complete killing (qualitative test results, the same below); for Shigella containing chlorine 20 mg / L solution for 5 minutes, or 5mg / L solution
