摘要
总结了铝的水化学特性、生物毒性及各国相关标准,综述了给水处理过程及输配水过程中铝浓度的变化规律和影响因素;结合目前饮用水中铝浓度超标的现状提出了减少管网出水铝浓度的相关措施以保障供水安全。今后应加强铝对输配水过程水质变化及各因素对铝沉淀溶解平衡的影响规律的研究。
In this paper, aqueous-chemical characteristics, bio-toxicity and related criterions of aluminum were presented. Aluminum disposition and distribution in water supplying system was summarized based on previous researches. Concentration variation characteristic of aluminum, transformation laws between different aluminum forms and their affecting factors were discussed. Finally, feasibility suggestions were proposed to reduce aluminum concentration in water supplying system. In the future, fundamental research on the factors affecting aluminum dissolve-sediment equilibrium and the effect of aluminum on water quality should be strengthened.
