| 摘 要： | 利用在酸性条件下铁阳极溶解产生的Fe^2 的催化及絮凝作用，采用电凝聚-空气氧化法去除草浆造纸黑液酸沉析滤液中的COD，实验结果表明：pH=3，中速搅拌，槽电压U=3v，空气流量Q=181／h和处理时间t=90min时此法对造纸黑液酸沉析滤液中的COD去除率可达83％，另外，还讨论了处理时间，槽电压，空气流量对COD去除率的影响。

| Abstract: | Using the catalytic and flocculation of Fe~2+ generated in acid by the dissolving of iron positive, this paper adopts Electrolytic Flocculation-Air Oxidation treatment COD of the filtrate of black papermaking liquor after lignin extraction in acid precipitation process. The experiment results indicate: when pH = 3,voltage is 3 v,air flow rate is 18 l/h and treatment time is 90 min, the COD removal rate is about 83%. Meanwhile the effect factors such as treatment time, voltage, air flow rate were discussed. |
