摘要
采用水热法和共沉淀法制备磁性纳米Fe3O4/Mn O2复合材料并作为光催化剂使用,运用XRD、FESEM、VSM等手段对该光催化剂进行表征,并将其用于光催化处理造纸废水生化出水。研究了催化剂的投加量、反应初始p H等因素对废水深度处理效率的影响。实验结果表明,在优化条件下,造纸废水CODCr的去除率可达57.67%,出水CODCr为50.84 mg/L。该光催化剂具备一定的可循环性,可以作为一种新型的非均相光催化剂用于造纸废水生化出水的深度处理。
Magnetic Fe3O4/Mn O2nanocomposite photocatalysts were prepared by hydrothermal method and coprecipitation process.The photocatalysts were characterized by means of XRD,FESEM and VSM,and then used to treat the biochemical effluent of paper-making wastewater.The effects of catalyst dosage and initial p H on the efficiency of wastewater treatment were studied.The experimental results showed that under the optimal conditions,the removal efficiency of CODCrin paper-making wastewater could reach 57.67%,and CODCrin the effluent was 50.84 mg/L.The photocatalyst has certain recyclability and can be used as a new heterogeneous photocatalyst for the advanced treatment of paper-making wastewater.
