摘　　要：由于水资源紧缺的问题,反渗透膜处理技术发展迅速。膜阻垢剂因能减缓膜组件的结垢、提高水净化效率,因而被广泛应用于反渗透膜处理技术。常见的膜阻垢剂有磷酸盐类、阴离子聚合物类、阳离子聚合物类以及绿色阻垢剂等,一般认为它们可以通过螯合、分散、晶格畸变等作用或阈值效应阻碍或缓解垢的形成。树枝状聚合物膜阻垢剂具有优异的阻垢性能,与其结构相似的球形聚电解质刷作为一种刷状聚合物膜阻垢剂也在膜处理领域中崭露头角。深入研究新型膜阻垢剂的阻垢机理可为设计开发针对性强、经济环保的高效阻垢产品奠定理论基础。In response to water scarcity,the reverse osmosis membrane treatment technology is being developed rapidly.Membrane scale inhibitors are widely used in this field to sluggish the scaling of membrane modules and improve water purification efficiency.Common membrane scale inhibitors include phosphorus-containing agents,anionic polymers,cationic polymers and green scale inhibitors.These inhibitors mitigate scale formation through chelation,dispersion,lattice distortion and threshold effects.Dendritic polymeric membrane scale inhibitors have excellent scale inhibitory properties.The structurally similar spherical polyelectrolyte brushes are also emerging as promising scale inhibitors in the field of membrane treatment.In-depth research into studying the scale inhibitory mechanisms of membrane scale inhibitors can provide theoretical basis for the better design and development of scale inhibitory agents that are green and effective.
