氯胺消毒供水系统问题分析与应对策略

Issues causes and coping strategy in chloraminated water distribution systems

经氯胺消毒处理的饮用水在管道中经过长距离输送后,水质会发生显著的变化。世界多地出台相关政策,要求强化给水管网水质在线监测工作,对水厂的生产、管理工作提出了更高的挑战。总结了氯胺消毒系统运行中存在的问题及其产生的机理,并从水厂与给水管网运行优化、水质预测管理等方面,提出了氯胺消毒系统水质下降的应对策略。

The quality of treated water disinfected by chloramine may get deteriorated after long distance transportation.Many countries around the world released relevant regulations required to strengthen the on-line monitoring of water quality in water supply network,which posed a higher challenge to the production and management of waterworks.The problems existing in the operation of chloramine disinfection system and its mechanism were summarized,also countermeasures for water quality deterioration of chloramine disinfection system from the aspects of operation optimization of waterworks and water supply network,as well as water quality prediction management were suggested.
