摘要
用酸化破乳-H2O2/ Fe2+氧化-混凝沉淀处理印刷线路板感光乳化废水。讨论了 pH值、H2O2的浓度、Fe2浓度对COD去除的影响。结果表明,酸化破乳、Fenton试剂氧化的pH值控制在3~4,混凝沉淀pH值控制在9~10,H2O2浓度为0.06mg·L-1,Fe2+浓度为0.8mg·L-1,反应温度为140℃左右时,COD总去除率达93.6%,具有良好的应用前景。
Description of treating mixed photosensitive wastewater from the printed circuit board plant with acidification demulsification-Fenton reagent oxidation-coagulating deposition was presented. Influence of pH. Fe2+ H2O2 on removing COD was discussed .The results showed that total removed at of COD reached 93.6% when pH in acidification demulsilication and Fenton reagent oxidation was 3-4, pH in coagulating deposition was 9-10,the concentration of H2O2 was 0.06mg· L-1,the concentration of Fe2+ was 0. 8mg· L-1. This technology will be being applied.
