水中残留铝对水质的影响及其监测必要性

Effects of Residual Aluminium in Drinking Water on Water Sanitary Quality and its Potential Risk

用聚合氯化铝 (PAC)处理后的生活饮用水中的残留铝含量极少被检测 ,随着 (PAC)的广泛使用 ,人类及生存环境可能因过多摄入铝元素而引发各种不良后果。本文从 PAC的混凝原理出发 ,详述了铝元素的存在形式 ;水中残留铝随 p H值的变化规律及其环境、生物影响等 ,分析水中铝含量的影响因素及严密监测水中铝含量变化的客观必要性。

The residual aluminium was seldomly determined in drinking water treated by polyaluminium chloride (PAC)With the widespread application of polyaluminium chloride to water coagulation,it was possible that the over intake of aluminium could result in some adverse consequences for human and their living environmentBased on the mechanism of water coagulativone of PAC,the compound formation of aluminium existing in drinking water,the re- gularity of the variation of the levels of residual aluminium with the pH value and its relative environmental and biological effects were introduced in detailsThe relative factors effecting the levels of residual aluminium in drinking water and the objective necessity of closely monitoring the variation of the residual aluminium in drinking water were analysed in the article
