纳米科技的快速发展为深度水处理技术革新提供了新的机遇。将纳米颗粒负载于毫米级多孔载体材料中制备成具有限域结构特征的纳米复合材料是推进纳米水处理技术实用化的主流方法。然而,目前水处理纳米技术领域的研究往往以单一污染的模拟溶液为主,对工业废水与区域饮用水中普遍存在的有机—无机复合污染的深度处理缺乏深入了解。本课题围绕水中有机—无机复合污染的深度处理,创制出系列新型水处理纳米复合材料,发展了基于“闪速冷冻”的载体孔径调控技术与基于“爆发成核”的纳米颗粒尺寸调控技术,实现了锆系、镧系等纳米复合材料的吨级量产;揭示了相关材料深度净化特征污染物的性能、机制与若干限域特性,为深入理解纳米复合材料深度净污过程、实现材料的构效优化提供了科学依据与方法支撑;在此基础上,开发了以锆系纳米复合材料为核心的工业废水与区域饮用水深度处理集成工艺,实现了电镀园区(1000 m3/d)、集成电路(1000 m3/d)等工业废水与高砷氟区域饮用水(50 m3/d)深度处理的工程应用示范;并在加拿大、香港等地实现了基于镧系纳米复合材料的地表水深度除磷中试(30 m3/d)应用验证。今后研究将继续关注纳米复合材料深度净污机制,提高材料构效调控水平,进一步升级完善基于纳米复合材料的深度水处理技术炳持续拓展其应用空间。The rapid development of nanotechnology provides new opportunities for process innovation in advanced water treatment.To advance the application of nanotechnology in practical water treatment,the preparation of macro-scale nanocomposite materials with nanoscale inner confined space has been reckoned as an effective approach.However,the current research in environmental nanotechnology mainly focuses on the simulated solution containing single pollutant,and the knowledge about the advanced treatment of the industrial wastewater and regional drinking water containing organic-inorganic complex pollution is still lacking.Focusing on the deep removal of organic-inorganic complex pollution,this study invented a variety of nanocomposites for water treatment,and developed the host pore-manipulating technology based on flash freezing and the nanoparticle size-adjusting technology based on burst nucleation,and realized the ton-scale manufacture of zirconium-and lanthanum-based nanocomposites.The decontamination performance,underlying mechanism and some unusual phenomenon under nanoconfinement were uncovered,providing the scientific basis and methodology support for structure-activity optimization on the nanocomposites.Furthermore,this study has developed the integrated processes centering on the zirconium-based nanocomposite for advanced treatment on industrial wastewater and regional drinking water,constructing the demonstration projects on the wastewater from electroplating park(1000 m3/d)and integrated circuit industry(1000 m3/d),and on the regional drinking water(50 m3/d)containing high levels of arsenic and fluorine.Also,the advanced removal of phosphorus from surface water by the lanthanum-based nanocomposite has been verified by the pilot-scale assays in Canada and Hong Kong(30 m3/d).Future efforts will be maintained on the underlying mechanism for advanced decontamination of the nanocomposites,on structure-activity adjustment of the nanocomposites,and on upgrading and spreading the advanced water treatment processes based on nanocomposites.
