多相催化臭氧氧化结合电催化氧化法处理制浆造纸废水的研究
Study on Multiphase Catalytic Ozone Oxidation Combined with Electrocatalytic Oxidation for Pulping and Papermaking Wastewater Treatment
摘要
Abstract
Based on multiphase catalytic ozone oxidation and electrocatalytic oxidation,this study designed an electrolysis deionized wa-ter 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 chem-ical 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 papermak-ing 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.关键词
