摘　　要：采用微电解技术处理棉杆半化学浆废水,讨论了其影响因素。通过单因素实验和正交试验确定了反应的最佳条件:pH值为4,碳铁质量比为0.5,反应时间为0.5h,填料中铁屑配用量为10g/L,其处理后废水CODcr的去除率为88%,色度去除率可达98%,理论上铁屑和碳的消耗量分别为0.0028 kg/m3和0.0014 kg/m3,出水水质得到很大程度的改善。最后应用红外光谱分析了木素结构的变化,进一步说明微电解法的处理效果。The micro-electrolysis method is applied in the treatment of cotton stalk semichemical pulp wastewater and the influencing factors are discussed in this paper. Through the single factor experiment and orthogonal experi- ment to determine the optimal reaction conditions, the results show that ： when pH = 4, the mass ratio of carbon to iron is 0.5, the reaction time is 30rain, and the amount of iron with filler is lOg/L, the CODer removal rate of treated wastewater is 80% , color removal rate can reach 95% , theoretically consumption of iron and carbon are 0. 0028kg/m3 and 0. 0014kg/m3 respectively, and the effluent quality has a large degree of improvement. Finally, application of the infrared spectrum analysis of the change of lignin structure, further explaines the treatment effect of micro electrolysis method.
