针对微污染水源水,就高锰酸钾和次氯酸钠预氧化技术与与饮用水常规混凝工艺组合联用开展了一些试验研究。结果表明:预氧化强化聚合氯化铝混凝工艺对原水中CODMn,UV254和浊度的去除;次氯酸钠预氧化时间小于5min;高锰酸钾预氧化在11min后反应完全;水体pH值改变不会影响预氧化的助凝效果。
For slightly polluted source water, some experiments were carried out on the combination of pre-oxidation of potassium permanganate and sodium hypochlorite with the conventional coagulation process of drinking water. The results showed that the preoxidation of CODMn, UV254 and turbidity in raw water was removed by pre-oxidation enhanced PAC coagulation process, the pre-oxidation time of sodium hypochlorite was less than 5min, the pre-oxidation of potassium permanganate was complete after 11min and the pH value of water body did not change Affect the pre-oxidation of the coagulation effect.
