| 摘 要： | 饮用水中铝的来源广泛，对人体健康构成危害。首先通过实验证明了水中的铝主要以颗粒形态存在，常规水处理混凝沉淀工艺能大幅度降低水体中铝的含量；进而以实验的方法对混凝剂种类，投药钽，pH值和温度等的影响进行分析，发现上述因素对除浊和除铝都有重要影响，浊度与铝的去除有较强相关性，但除铝对工艺条件的要求比除浊更严格；通过优化，强化常规水处理工艺，在选择混凝剂品种和混凝条件时兼顾除浊和除铝的要求，对生产过程实施有效的监控调节，使出水残余铝达到水质标准的要求是可行的。 |
| 关 键 词： | 常规水处理 混凝 沉淀 浊度 残余铝 |

| Abstract: | Aluminium in drinking water has detrimental effect on human health .Bench-scale experiments indi-cated that conventional drinking water treatmen t processes,such as coagulation and sedimentation,could sig-nificantly reduc e residual aluminium in colloid form in water.The effect of a type of coagulant and its dosage,pH and temperature etc.were further investigated.It was foun d that they had pronounced impact on the removal of turbidity and aluminium that had good correlation.However,the requirements for removing aluminium are more stringent than those for turbidity.By choosing a suitable type of coagulant and the optimum conditions for removal of aluminium and turbidity,the conventi onal treatment process can be optimized.Therefore,it is feasi-ble to control the contents of residual aluminium to satisfy the standards for drinking water quality. |
| Keywords: | conventional water treatment coagulation sedimentation t urbidity residual aluminium cor-relation |
