摘　　要：黏性泥沙絮凝一直是研究者们广泛关注的重要课题,以往的研究较多地关注了泥沙特性及动力条件对于黏性泥沙絮凝的影响。近年来,研究者们逐渐认识到环境介质条件(如水体中的有机质、无机电解质等)对于黏性泥沙絮凝也有重要的影响。综合分析了有机质与无机电解质对黏性泥沙絮凝的影响的研究现状,从微观角度解释了其絮凝机理,指出了现有研究中存在的不足,展望了未来的发展方向。Cohesive sediment flocculation has always been an important topic for researchers. More attention were paid to the influence of sediment characteristics and dynamic conditions on the flocculation of cohesive sediment in previous studies. In recent years,researchers have come to realize that environmental media conditions（ such as organic matter in water,inorganic electrolytes,etc.）for cohesive sediment flocculation also has an important impact. This paper focuses on the influence of organic matter and inorganic electrolyte on the flocculation of cohesive sediment, explains its flocculation mechanism from a microscopic point of view and puts forward the shortcomings of the existing research and future development direction.
