摘　　要：为了在本质特征上定量说明水中无机阳离子混凝剂浓度与胶体稳定性的关系，提出了一种新的研究混凝过程胶体电荷变化的本质参数──流动电流（ＳＣ）．研究了无机阳离子混凝剂的性质和浓度与电动特性参数之间的一般规律及等电点特征，考察了以ＳＣ表征混凝剂对水中胶体颗粒物作用的特性与效能，从而提出了一种研究混凝和在线监测水中胶体电荷相对于混凝剂投加量变化的有效方法．A new essential factor of electrokinetic characters,streaming current(SC)was introduced into the study of coagulation processes,and the relative law and isoelectronic point between electrokinetic parameters and concentration or efficiency of inorganic canon coagulants were studied.Furtherly,in the paper the characteristics and functions to express coagulants affecting on colloid particles by SC have been investigated and an effeCtive methed was presented for studying on the relationship between the coagulation,detecting colloid potential in line and optimum dosage of coagulants.
