| 摘 要： | 混凝剂具有多种溶液形态，每种形态对混凝过程的作用不同，因而对流动电流的影响也不同，本通过实验及理论分析，阐述了一般水处理条件下的流动电流检测器（ＳＣＤ）对混凝剂的检测原理，分析了水中混凝剂形态改变过程中流动电流的变化特征，探讨了ＳＣＤ对不同形态混凝剂的响应灵敏度，结果表明，中性条件下铝盐的混凝过程以及三价铁阳离子对流流具有较为灵敏的正增值效果。

| Abstract: | Coagulants have several solution forms in water, which effect on the coagulation processes with different manners, so their influence on streaming current is also different. Detection principle of streaming current in normal water treatment condition is introduced in this study.The characteristics of streaming current varying with the coagulant forms was analyzed and the response sensitivity SCD on different solution forms of coagulants was investigated. It was demonstrated that the coagulation processes of aluminum sulphate under neutral water conditions and trivalence ion cations can increase streaming current value remarkably and sensitively. |
