| 摘 要： | 采用微电解-絮凝工艺处理皂素废水,COD去除率可提高至90%。铁碳质量比为1∶1,原水pH=1.1,HRT=90 min为微电解—絮凝工艺的最佳条件。在此条件下投加H2O2对该工艺进行强化,当H2O2投加量为8 mL/L时,COD去除率可达57%,B/C显著提高,同时对皂素废水中的氨氮、TP、色度也有很好的去除效果。

| Abstract: | Use micro-electrolysis and flocculation process to treat saponin wastewater,the removal rate of COD can increase to 95 %.The best condition is the Mass ratio of Fe and C was 1∶1,pH of the raw water was 1.1,reaction time was 90 min.In the condition,adding H2O2 to strengthen the micro-electrolysis-flocculation process.When the dosage of H2O2 was 8 mg/L,the removal of COD was 57 %,B/C value remarkable increased.Meanwhile,removal effect on NH4-N,TP and color were better. |
