摘　　要：采用高效气浮-水解酸化(UASB)-好氧(生物铁强化接触氧化)耦合工艺处理废纸再生造纸废水。运行结果表明,此工艺能有效处理废纸再生造纸废水,COD去除率达到93.9%,BOD去除率达到85.4%,SS去除率达到96.6%。生物接触氧化池中投加适量亚铁离子形成的生物铁强化反应器,可以将废纸再生造纸废水的COD、BOD、SS去除率分别提高10%、13%、21%。Integrated high-efficiency air floating-hydrolysis （UASB）- aerobic process Coin-ferric contact oxidation） was applied to treat regenerated papermaking wastewater. The results show that this system has high treatment efficiency of COD, BOD, SS with the 93.9%, 85.4%, 96.6% removal rate respectively. The bio-ferric contact oxidation with adding certain amount of ferrous ions to bio-contact oxidation raised the COD, BOD, SS removal rate by 10%, 13%, 21% respectively compared with the value in the absence of ferrous ions.
