水中天然有机大分子对混凝影响的电动特征
- ELECTROKINETIC CHARACTERISTICS OF HUMIC AND DANNIC ACID IN WATER EFFECTING ON COAGULATION
- 摘要：以流动电流为特征参数，研究了水处理混凝过程中，天然有机大分子对水中悬浮胶体颗粒、无机盐混凝剂及其相互作用过程所表现出的电动性质特征，探讨了HA和DA（腐殖质和单宁）影响混凝过程电动特性的条件与机理。结果表明，HA和DA的存在大大降低了无机盐混凝剂对水中悬浮胶粒作用的电动效果，这与二者对混凝效果的影响具有一致性。
- Abstract：Taking steaming current as the electrokinetic parameter, this paper focuses on the electrokinetic characteristics of humic (HA) and dannic acid (HA) effecting on suspended colloid particles, inorganic coagulant and their electrical neutralization ability in water coagulation processes. In addition, the factors and mechanism of the affections were investigated systematically. The result indicates that HA and DA can remarkably suppress the electrokinetic effect of inorganic coagulation on the charged particles in water, which is in accordance with their influence on coagulation.
