【摘要】：目的比較酸性氧化電位水與含氯消毒劑殺菌效果,為消毒方法選擇提供參考。方法采用懸液定量殺菌試驗和現(xiàn)場消毒試驗方法,比較酸性氧化電位水與含氯消毒劑的殺菌效果。結(jié)果該酸性氧化電位水原液ORP值1 100 m V、p H值2.40、有效氯含量63 mg/L。用該酸性氧化電位水原液對懸液內(nèi)金黃色葡萄球菌、大腸桿菌作用1 min,殺滅對數(shù)值均達到5.0以上;對白色念珠菌作用1 min,殺滅對數(shù)值均達到4.0以上。有效氯濃度150 mg/L的氯胺T水溶液殺菌效果與酸性氧化電位水相當(dāng)。分別用酸性氧化電位水和氯胺T水溶液擦拭消毒表面,作用5 min,對自然菌殺滅對數(shù)值均達到1.0以上。結(jié)論酸性氧化電位水與有效氯150 mg/L的氯胺T水溶液殺菌效果相當(dāng)。
[Abstract]:Objective to compare the germicidal efficacy of acid oxidizing potential water and chlorinated disinfectant and to provide reference for the selection of disinfection methods. Methods suspension quantitative germicidal test and field disinfection test were used to compare the germicidal efficacy of acid oxidizing potential water and chlorinated disinfectant. Results the ORP value of the acidic oxidizing potential water solution was 1 100 m V / P H = 2.40, and the effective chlorine content was 63 mg / L. The killing logarithms of Staphylococcus aureus and Escherichia coli in suspension were above 5.0 for 1 min and 4.0 for Candida albicans exposed to the acidic oxidizing potential water solution for 1 min. The bactericidal efficacy of chloramine T aqueous solution with 150 mg / L available chlorine concentration is equivalent to that of acidic oxidizing potential water. The surface was disinfected by acid oxidizing potential water and chloramine T solution respectively. After 5 min contact, the logarithmic value of killing natural bacteria reached more than 1.0. Conclusion Acid oxidizing potential water has the same bactericidal efficacy as available chlorine 150 mg / L chloramine T solution.
