摘　　要：采用微电解法对碱法麦草制浆的中段废水进行深度处理,实验研究铁炭比、pH、用铁量、反应时间等因素对处理效果的影响。结果表明:在pH为3.5、铁炭比为1.4、用铁量为700mg·L-1、反应时间为35min条件下处理效果最好,处理水不但可以满足新的排放标准(GB3544-2008),而且完全达到回用水质要求。The micro-electrolysis process has been applied to the advanced treatment of gray water from straw pulping. The effects of operational conditions such as pH,Fe/C,iron quantity and reaction time, have been studied. The experimental results show that when pH 3.0, Fe/C ratio 1.4, iron quantity 700mg·L-1 and reaction time 35min, the treating effect is best. The quality of the final water not only can completely satisfies the new discharge standard （GB3544-2008）,but also the recycle requirements.
