摘要
本文对液氯,氯胺,二氧化氯和短时二氧化氯后转氯胺的顺序消毒工艺消毒时卤乙酸(HAA s)的形成规律进行了研究.研究结果表明,用氯胺和二氧化氯作为替代消毒剂,可大大降低HAA s的生成量;且短时二氧化氯后转氯胺的顺序消毒工艺产生的卤乙酸量比单独用氯胺消毒产生的卤乙酸量进一步的降低.
The formation of haloacetic acids in water is investigated as water is disinfected by free chlorine,chloramines,chlorine dioxide (ClO2) and short-term ClO2 plus cloramines. Results show that the use of cloramines and chlorine dioxide as alternate disinfectants can remarkably control the concentration of haloacetie acids. The haloacetic acid level in water that is disinfected by short-term ClO2 plus ehloramines is lower than that treated only by chloramines.
