摘要
采用电絮凝-微滤组合工艺技术去除水中过量的腐殖酸,探讨了电流密度、极板间距和pH值对去除腐殖酸效果的影响.结果表明,电絮凝-微滤组合技术去除腐殖酸效果明显,电絮凝反应器的最佳工作参数为电流密度=3.17 A.m-2,极板间距=1.0 cm,pH值在酸性范围内.
By Electrocoagulation-Microfiltration (EC-MF), the excessive humic acid in water was removed. Influence of current density, inter-electrode distance and pH value on removal efficiency of the humic acid were investigated. The results demonstrated a favorable removal of humic acid with EC-MF technique. The optimal conditions for removing humic acid by using the proposed instrument are pH acidic, current density 3.17 A · m^-2 and electrode distance 1.0 cm.
