聚硅硫酸铝混凝去除微污染原水纳米颗粒物(英文)

Removal of Nanometer Particles in Micropolluted Water Source by Coagulation with Polysilicate-Alumium

制备了絮凝剂聚硅硫酸铝(PASS),采用透射电镜(TEM)和准弹性激光散射技术(PCS)对PASS、聚合氯化铝(PAC)、硫酸铝进行了表征.同时进行了珠江水系原水的强化混凝处理,并利用PCS对常规混凝和强化混凝前后水中纳米级颗粒物的大小与分布进行了测定与研究.

Polysilicate-alumium was made and characterized by transmission electron microscope and technique of lasar light scattering with other coagulants. The Peal River supply water was treated by enhanced coagulation and the size and distribution of nanometer particles in the water before or after coagulation were determined and studied.
