摘　　要：结合研究应用实例,简单介绍了近年来切向超滤技术的机理、滤膜的截流和吸附特性、超滤过程中胶体有机碳的回收率以及渗透行为、该技术在环境科学的胶体有机碳分离方面的应用和存在的问题。利用珠江水系水体的胶体分离试验,验证了切向超滤技术的渗透模型。Combined with practical application examples, the mechanism of the cross-flow ultrafiltration technique, the characteristics of retention and adsorption of the ultrafiltration membrane, and the recovery rate and penetration of colloidal organic carbon during the process of the ultrafiltration are briefly introduced in this paper. The application and existing problems of using the cross-flow ultrafiltration technique to separate colloidal organic carbon are also described. The filtration model of the cross-flow ultrafiltration technique was validated with the experiment of separating the colloid from the Pearl River water.
