复合电解槽及其化机浆制浆废液复合电解脱色的方法
摘要：
本发明公开了一种复合电解槽及其化机浆制浆废液复合电解脱色的方法。该复合电解槽由隔板分隔成多个电解槽单元，每一电解槽单元两侧的阴极板和阳极板相对平行设置，电解槽单元内设有导电粒子电极和惰性粒子电极的填料层；电解槽底部设有支撑布气板、曝气管，曝气管下部设有污泥槽。化机浆制浆废液复合电解脱色的方法是废液首先用斜网过滤，筛网为50～80目；然后把废液酸度降低到pH值为3～3.5.，沉淀1.5～2小时，再使沉淀后的滤液通过复合电解槽进行脱色。本发明脱色效果显著，总体运行费用低，占地面积小，投资小，预处理效果好，悬浮物去除率在95％以上，色度去除率在90％以上，COD去除率在60％以上。
摘要（英）：

A composite electrolyzer for the electrolytic decoloring of chemico-mechanical pulping sewage is composed of multiple unit electrolyzers formed by dividing the composite electrolyzer by bulkheads and containing the plate anode, plate cathode and filler layer consisting of electric conductive particles and inertial particles, a supporting air distributing plate, aerating tube and sludge bath. Its electrolytic decoloring method for the chemico-mechanical pulping sewage includes such steps as flitering by oblique net, regulating pH=3-3.5, depositing, filtering and decoloring in said composite electrolyzer.
