| 中文摘要: |
| 本研究基于多相催化臭氧氧化法和电催化氧化法，以镧系稀土金属氧化镧（La2O3）和氧化铈（CeO2）的复合物La2O3-CeO2为阳极，铂片为阴极，设计了可产生羟基自由基（·OH）和臭氧（O₃）的电解去离子水装置。将该装置用于化学机械浆制浆废水、白纸板白水、本色牛卡纸白水及生化废水（SBR水）的净化处理，并研究了处理后SBR水用于纸张抄造时对制备纸张物理性能的影响。结果表明，在电流为10 A时，该装置产生的O3流量为4 g/min；用于处理上述制浆造纸废水时能够明显降低其化学需氧量（CODCr，去除率30.4%~81.6%）、颗粒电荷需求量（PCD，去除率49.5%~72.6%）和浊度（去除率81.6%~87.4%）等，且不产生污泥。处理后SBR水用于纸张抄造时，最高可实现50%的清水替代，且制得纸张性能良好。 |
| Abstract: |
| Based on multiphase catalytic ozone oxidation and electrocatalytic oxidation， this study designed an electrolysis deionized water system capable of generating hydroxyl radicals （·OH） and ozone （O₃）， utilizing a composite anode of lanthanum oxide （La₂O₃） from the lanthanide series， and cerium oxide （CeO₂）， paired with a platinum plate cathode. This system was used to treat pulping wastewater of chemical mechanical pulp， white water of whiteboard， white water of unbleached kraft cardboard， and biochemical wastewater （SBR water）. This study also investigated the impact of reusing treated SBR water in papermaking process on prepared paper mechanical properties. The results indicated that at a current of 10 A， the system generated an O₃ flow rate of 4 g/min. When treating the aforementioned pulping and papermaking wastewater， it could significantly reduce chemical oxygen demand （CODCr， removal rate of 30.4%~81.6%）， particulate charge demand （PCD， removal rate of 49.5%~72.6%）， and turbidity （removal rate of 81.6%~87.4%） without producing sludge. Upon reuse of treated SBR water in the papermaking process， up to 50% fresh water replacement was achievable， and the prepared paper had excellent properties. |
