SH-A工艺处理煤制油废水的研究

Study on biofacies of coal liquefaction waste water by Sharon-Anammox process

采用SH-A强化脱氮除碳工艺处理煤制油废水,进水CODCr<2500mg/L,氨氮<250mg/L,控制一段好氧反应器中水温为33℃,pH值为8.0,溶解氧为2.0mg/L左右的条件下,反应器中生物相丰富,活性强,废水CODCr去除率达70%,氨氮硝化率达60%。

SH-A enhanced biological denitrification and carbon removal process was used for the treat- ment of coal liquefaction wastewater. The chemical oxygen demand of influent was controlled below 2 500 mg/L and ammonium below 250mg/L. The biofacies of the activated sludge were abundant with stronger activity when the conditions of the first aerobic reactor were kept as followed, temperature about 33℃, pH value about 8.0, and dissolved oxygen about 2.0mg/L. The chemical oxygen demand removal efficiency reached up to 70%, ammonium nitration rate reached 60% at the same time.
