摘要
本研究以人造石英石尾泥为研究对象,通过化学改性制备出了人造石英石尾泥改性混凝剂。未改性尾泥具有一定的混凝作用,改性后尾泥粒径减小、表面粗糙多孔隙、比表面积增大,这些性质的改变均有助于提升混凝效果;尾泥改性混凝剂对印染工业园区污水、校园污水处理厂二沉出水均具有良好的浊度、TP去除效果;混凝活性物质的电性中和作用、疏松表面多孔隙的结构以及惰性尾泥颗粒形成絮体后的吸附、卷扫及网捕作用是混凝反应主要机理。以人造石英石尾泥为原料改性制备混凝剂具有改性条件温和、生产成本低、水处理效果好等优势。
Employing the artificial quartz tail mud as the research object,the modified coagulant was prepared by chemical modification.The unmodified tail mud has a certain coagulation effect.After modification,the particle size of tail mud decreased,the surface became rougher,the porous structure and the specific surface area increased and the changes of these properties were helpful to improve the coagulation effect.The tail mud modified coagulant had good turbidity and TP removal effects on the sewage of printing and dyeing industrial park,secondary effluent of campus sewage treatment plant.The electric neutralization of coagulant active substances,the loose surface porous structure of modified coagulant,and the adsorption,sweeping and netting of inert tail mud particles after forming flocs were the main mechanisms of coagulation.Using the waste tail mud from the production process of artificial quartz stone as raw material to modify and prepare coagulant had the advantages of mild modification conditions,low production cost and good water treatment effect.
