| 摘 要： | 传统城市供水管网一般在净水厂实行消毒以减少用户受到病原体及各种水传播疾病的危害.既要保证足够的氯残留,又要减少过量氯产生的气味和可能的消毒副产物(DBPs),传统的消毒方法经常是不可能的.为了解决这对矛盾,二次加氯将会是个很好的解决策略.二次加氯的优势已经吸引了国内外许多专家学者的关注,对二次加氯的研究进展进行了综合的论述,从新的角度对现有的优化模型进行了分类,并比较和推荐了认为可行或相对较好的模型.

| Abstract: | Booster chlorination at selected points in the potable water distribution system is an attractive alternative to the conventional one stage chlorination at the water purification plant; it is practiced to ensure a desirable residual free chlorine concentration in water received by all end users at a lower overall consumption of chlorine and less productions of harmful and/or taste-odor causing disinfectant by-products (DBPs).Available basic and improved booster chlorination models are presented, sorted and compared in detail. It is recommended to consider specific conditions for the case of study in selecting a model for identifying the locations for booster chlorination and to employ a chlorine dose model based on the sum of square of differences between the set residual chlorine concentration and actual concentrations found at the booster chlorination stations. |
