摘要(Abstract)：

实现精处理出水氯离子指标的有效监控，对保障精处理出水水质、运行工艺调整、延长运行周期等具有关键作用。根据离子交换平衡理论，分析比对了精处理氢型与铵型运行方式的运行特点、出水水质以及树脂再生度要求；并通过实验室模拟以及某电厂精处理混床运行周期跟踪试验，重点研究了精处理出水氯离子迁移特性。结果表明：氢型阶段树脂再生度要求低，该阶段主要以除盐为主，不易发生漏氯现象；转化阶段随着出水pH值不断升高，对树脂再生度要求也不断提高，当凝结水中含有氯离子时容易发生氯离子的溢出现象；铵型运行时混床不再以除盐为主，出水氯离子质量浓度与凝结水相当。因此，对于精处理出水(尤其是铵型运行时)，实现氯离子有效监控对于保障出水水质是必要的，同时将氯离子作为监控指标之一，不仅可有效保障精处理出水水质，同时可以指导精处理运行工艺调整，在保障机组安全运行的前提下达到显著延长精处理运行周期的目的。
