四平市饮用水理化性质分析

Analysis on Physicochemical Properties of Drinking Water in Siping City

主要以热水、自来水、桶装水和瓶装纯净水这4种水样为检测目标,对其p H值、总硬度、电导率、氯化物和菌落总数进行了测定。结果表明,热水和自来水的各指标差别不大;4种不同的水源中,氯化物浓度和菌落总数这2项指标差别较显著。综合各种指标,桶装水和纯净水都是比较健康的饮用水,比热水更适合饮用。

Taking boiling water, piped water, bottled water and pure water as research objects, pH value, hardness, conductivity, chloride content and total number of bacteria of the samples were determined. The results showed that chloride content and the total number of bacteria were obviously different in all water samples, but monitoring indexes of boiled water and cold water were similar. it’s pointed out that bottled water and pure water are healthier and better than boiled water.
