摘　　要：研究了酸析-微电解法处理草浆制浆黑液,实验结果表明,酸析时pH值为3,COD的去除率为69.5%;微电解过程中曝气量为0.4L/min、反应时间为30min、铁炭质量比为2∶1,COD的去除率为62%,有效地减轻了黑液的污染负荷。Straw pulp black liquor treated by acid precipitation and micro-electrolysis process was studied. The results showed that the pH is 3 in acid precipitation process and the COD removal rate is 69.5% ; for micro-electrolysis treatment, the optimum conditions are ;adding air quantity is 0.4L/min,reaction time is 30 minutes and the weight ratio of iron to carbon is 2 ： 1, and the COD removal rate is 62%. The methods make an evident effect to decrease the pollution from straw pulp black liquor.
