我国许多自来水厂广泛使用铝盐净水剂。有关铝盐净水剂的标准只有硫酸铝 ,而对聚合氯化铝和其他复合铝盐净水剂尚无统一标准 ,从而给卫生评价工作带来了一定的困难。本实验比较了两种不同铝盐净水剂混凝沉淀的效果 ,以期为指导净水剂的使用和对净水剂卫生评价提供一定的科学依 Many water plants in China widely use aluminum salt water purification agent. The standard aluminum salt water purifying agent is only aluminum sulfate, while there is no uniform standard for polyaluminum chloride and other composite aluminum salt water purifying agents, which brings certain difficulties to the health assessment. In this experiment, the effect of coagulation and sedimentation of two different aluminum salt water purifiers was compared in order to provide a scientific basis for guiding the use of water purifiers and evaluating the health of water purifiers
