高锰酸盐复合药剂(PPC)与氯胺联用预氧化灭活试验研究

为了减少预氯化时产生的大量消毒副产物,保障饮用水的化学安全性,我们寻找更为安全可靠、更能发挥各种消毒剂长处的饮用水预氧化方式来代替预氯化.本文着重研究了氯胺和PPC(高锰酸钾复合药剂)这两种安全的消毒剂单独以及二者联用对原水中细菌、总大肠杆菌群的灭活效果.用Berenbaum公式判断两种消毒剂联合作用的性质.研究结果表明:氯胺和PPC两者联用预氧化对原水中的微生物具有协同灭活效果,可以提高细菌、大肠杆菌的灭活率,保障饮用水的生物安全性.同时可以减少消毒副产物的生成量,保障饮用水的化学安全性.因此,可以作为新的安全可靠的预氧化方式来代替预氯化.

Study on Pre-oxidation Disinfection by Combination of Chloramine and PPC

In order to reduce the plentiful disinfect by products and ensure drinking water's chemical safety.We looking for the more effective and the more safe methods to replace pre-oxidation by chlorine.This paper put more emphases on the study of controlling of the total count of bacteria and the total coliform group by the combination of PPC and chloramine and by either of them.The character of combination action was demonstrated by the mathematic method of Berenbaum.Results show that the combination disinfectant of PPC and chloramine is more effective than using either disinfectant alone.It can guarantee the drinking water's biologic safety and the chemical safety.So this method can be used to replace the method of pre-oxidation by chlorine.
