摘　　要：系统地分析了常规条件下流动电流混凝投药自控系统设定值的两类主要影响因素 :一类是对流动电流检测值直接产生影响的因素 ,如源水水质、混凝剂条件 ,以及取样系统位置和结构上的变化 ;另一类是对混凝沉淀过程发生影响 ,从而导致流动电流设定值有所改变的因素 .在此基础上 ,提出了流动电流设定值选取时的建议 。Two kinds of main factors affecting the set point of a streaming current detector are analyzed in this paper. One kind of factors, such as the quality of water sources and the condition of coagulator, affects the test value directly;the other kind of factors affects the process of coagulation and sedimentation, and leads to the change of the set value. Based on the analysis, some suggestions are proposed for the selection of the set point of a streaming current detector.
