摘　　要：为符合造纸工业废水新的排放标准并解决废水和回用问题,对经二级生化处理的碱法麦草浆中段废水采用电化学法深度处理进行了试验研究,对比了用铁量、铁碳比、pH值、反应时间对其处理效果的影响。试验结果表明:在最佳处理工艺条件下,处理后出水的CODC r、色度及浊度分别为115.6mg/L、25倍、31NTU,出水水质不但可以满足新的排放标准(GB3544-2008),而且完全达到回用水要求。In order to meet the new papermaking wastewater discharge standards and reuse,the electrochemistry process was applied to the advanced treatment of straw pulp washing,screening and bleaching effluent.The effects of operational conditions,such as iron quantity,Fe/C,pH and reaction time,were studied.The experimental results show that under the best treating technological conditions,the CODCr,colority and turbidity of outlet water were 115.6mg/L,25.5times and 31NTU respectively.The treated water not only meets the states new discharge standards（GB3544-2008）,but also satisfies requirements of reuse.
