摘　　要：通过单一污染物试验,分析了腐殖酸对长流程反渗透系统的污染过程,指出了腐殖酸污染会导致系统工作压力上升,透盐率下降及前后段通量失衡的现象.复合污染试验表明,钙离子与腐殖酸的络合效应使系统达到固定污染效果所需的运行时间大大缩短,且系统透盐率高于单一污染.By single fouling experiments, fouling processes of long flow RO system by HA were analyzed, and it was pointed out that fouling by HA would cause the increase of system work pressure, the decrease of system salt permeability, and the aggravation of system flux imbalance. The compound fouling experiments showed that due to complexing effect caused by Ca2＋ and HA, the system fouling time was greatly shortened and the system salt permeability was higher than single fouling.
