| 摘 要： | 生物铁法是一种新型的强化活性污泥法,处理高浓度、难生物降解维生素B1生产废水具有很大的优势.当进水COD浓度维持在8000 mg/L时,COD的去除率可达94%以上,比普通活性污泥法高出9.7%.生物铁法污泥絮凝沉淀效果好,能保证系统有较高浓度的回流污泥,从而使曝气池的污泥浓度得到提高,COD的去除率也会相应地提高.

| Abstract: | Bio-ferric process,which is a new enhanced activated sludge process,has great advantages in treatment of high concentrated and refractory biodegradation wastewater from producing vitamin B_1.When COD concentration in effluent maintains 8000 mg/L,COD removal rate can exceed 94 %,which is 9.7 % higher than common activated sludge process.Bio-ferric activated sludge floc with fine sedimentation effect can ensure the system provided with return sludge of higher concentration,thus sludge concentration of aerobic tank increases,COD removal rate increases correspondingly. |

| Keywords: | bio-ferric process vitamin B_1 refractory biodegradation pharmaceutical wastewater high concentrated COD high sludge concentration |
