摘　　要：采用电絮凝工艺对含难降解有机物和重金属的造纸废水进行处理,探究了不同条件下污染物的去除效果,进而分析了污染物的主要去除机制。在优化条件下,有机物的去除率为38.7%。5种荧光组分在降解过程中表现出不同的去除效果,芳香类小分子有机污染物和类色氨酸有机组分的荧光强度分别增加了510%和190%,而类富里酸和类富里酸与类腐殖酸混合物被完全去除。电絮凝对重金属及硬度有去除作用,其中砷、锰和硬度被有效去除。The electrocoagulation(EC)was used to treat the papermaking wastewater containing refractory organics and heavy metals.The removal effect of pollutants under different conditions was investigated,and then the main re-moval mechanism of pollutants was analyzed.Under the optimized conditions,the removal rate of organic matter was 38.7%.The five fluorescent components showed different removal effects during the degradation process.The fluore-scence intensity of aromatic small molecule organic pollutants and tryptophan-like organic components increased by 510%and 190%,respectively,while the fulvic acid-like and humic acid-like components were effectively removed.EC was able to remove heavy metals and hardness,in which arsenic,manganese and hardness were effectively removed.
