复合絮凝剂去除册田水库污染物实验

Study on composite flocculation of water pollutants in Cetian reservoir

以"PAC+PDADMAC"复合、"PAC+PAM"复合、PDADMAC为絮凝剂,用于册田水库污染物强化混凝处理。通过混凝烧杯实验,以TOC、色度、浊度、Zeta电位为考察指标,研究"PAC+PDADMAC"复合投加对册田水库水中污染物的去除,并对其絮凝作用机理进行了探讨。结果表明,"PAC+PDADMAC"复合投加对册田水库水中的浊度、色度T、OC具有更好的去除效果,去除率分别高达93%,90%和71%。

The enhanced flocculation treatment by different composite flocculants,such as PAC＋PDADMAC,PAC＋PAM,PDADMAC in the Cetian reservoir was studied.The experiments were carried out with dosing PAC＋PDADMAC as the composite flocculants.TOC,color,turbidity and Zeta electric potential were used as inspecting indexes to investigate the pollutant removal in Cetian Reservoir.The results showed that the composite flocculants PAC＋PDADMAC had better removal effect than others.Removal rates of turbidity,color and TOC were high up to 93%,90% and 71%,respectively.
