摘要
在造纸废水生化段投加生物活性磷替代传统磷营养剂,改善了活性污泥SVI,提高了污泥沉降性能,丰富了活性污泥中微生物种类,增强了系统抗高负荷废水冲击能力,生化段CODCr去除率上升1.9%,出口总磷<0.1mg/L。
Super phosphor（SP） has been added to the biochemical tank of paper-making wastewater treatment process to replace the traditional phosphor nutrition. It shows that both the SVI and the flocculation quality of MLSS are improved. The category of micro-organism in active sludge is enriched and the ability of shock resistance caused by high load wastewater is also enhanced. In this work,the CODcr removal efficiency of biochemical tank raises 1.9%, and the discharge index of total phosphor（TP） is less than 0.1 mg/L.
