摘　　要：实验采用激光微米粒度测试仪在线测定混凝处理时絮粒的成长过程,并初步探讨了搅拌槽内三种絮凝剂PAC、PFC、PAM以及复配的絮凝剂PAC与PAM、PFC与PAM处理长江水时的絮凝动力学。研究结果表明,在絮凝初期絮团的生长过程可以用絮凝动力学方程ln N/N0=-kt描述。其中,k值为初始速率常数。k值越大,絮凝速度越快,最终的混凝效果越好;反之,k值越小,则絮凝速度越慢,最终的混凝效果越差。在实际应用中可以通过k值的大小来确定混凝时所需要的最佳条件。In this paper, the flocculation dynamic of three kinds of flocculent and their combination were studied with the laser particle analyzer. It showed that, the growth process of floc in the early stage of flocculation could be described with the flocculation dynamic equation In N/N0=kt.In this equation, k means the initial rate constant of flocculation, the higher k value was, the faster flocculationwas, and viceversa. In practice, the condition of flocculation could be adjusted according to the k value.
