摘　　要：铝是饮用水卫生标准的一项重要水质指标,控制出厂水残余铝的研究对于水处理运行有着重要意义。通过烧杯试验,比较不同的pH值环境和不同盐基度的聚合氯化铝对絮凝效果的影响和残余铝浓度的影响。结果表明:在本实验原水条件下,聚合氯化铝的盐基度在80%以上,pH在7.0~7.5的时候,残余铝得到良好的控制。本实验的方法和结论对于指导自来水厂生产运行有重要的参考价值。Aluminum is an important water quality indicator in drinking water quality standard,and the research of contrlling the residual aluminum of treated water is of great significance for water treatment operation.In this paper,the influence of different pH value environment and different basicity of polymeric aluminum chloride on the flocculation effect and the influence of residual aluminum concentration were compared by jar-test.The results showed that the residual aluminum can be well controlled when basicity of PAC is higher than 80%,and pH is between 7.0 and 7.5 under the raw water condition.The method and conclusion of this experiment have important reference value for guiding the operation of drinking water treatment plant.
