摘　　要：该文探讨了含铝沉积物对微量金属元素的蓄积作用,以及原水水质、水处理药剂、溶液pH和水流状态等因素改变时对含铝沉积物结构稳定性和微量金属元素释放特性的影响。为减少输配水过程中微量金属元素的释放,保障管网稳定运行和居民饮水健康,建议通过水质调节控制管网中含铝沉积物的生成量。该研究给出了常见微量金属元素的最大允许蓄积量,并指出了今后的研究方向。The accumulation of trace metal elements on aluminum containing sediments, the effects of variations of raw water quality, chemical reagents, solution pH and drinking water flow condition on stability of aluminum containing sediments and the release of trace metal elements were discussed. In order to decrease the release of trace metal elements, and to ensure the pipe operation and human safety, water quality adjustment was suggested to avoid aluminum containing sediments formation in drinking distribution sys- tem. The maximum amounts of accumulation of common trace metal elements were given. Future trends of development in this field were also proposed.
