从Larson指数分析无机阴离子对饮用水水质稳定性的影响

Analysis of the influence of inorganic anions on the stability of drinking water quality by the Larson index

综述了自来水中硫酸盐、氯化物、硝酸盐和氟化物对水质以及人体健康的影响,提出了综合考虑以上四种阴离子的Larson指数,并通过Larson指数分析了绵阳市某地表水厂出厂水的水质稳定性。结果表明,各Larson指数均未达到腐蚀性水质的临界范围,该厂生产的自来水不会对输水管道及水质造成不良影响。

The influence of sulphate, chloride, nitrate and fluoride on drinking water quality and human health was summarized, the Larson index considering the four inorganic anions comprehensively was proposed, and the stability of treated water quality was analyzed by the Larson index in a waterworks in Mianyang City with surface water source. The results showed that the Larson indexes did not reach the threshold scope of corrosion water quality, the treated water of the waterworks would not have adverse effects on distribution pipelines and water quality.
