摘要
通过饮用水除铝的一系列生产实验,主要研究在处理流程中水温、pH值对残余铝的影响。提出残余铝随水温升高呈增加趋势,最佳pH值随水温的增加而降低。调整pH值可以调整溶解铝和颗粒铝的比例,从而改善残余铝的可去除率。在此基础上对水厂生产运行提出了一些建议。
A series of experiments are designed to study the removal of residual aluminum in water plants. Some factors, such
as temperature and pH value are studied. As temperature rises the concentration of residual aluminum increases while the opti-
mum pH value decreases. Adjustments of pH value can change the portions of dissolved aluminum and particle aluminum, so
the removability of residual aluminum is improved. On this basis some proposals are offered for operation of water plant.
