摘　　要：采用连续式UV-Fenton氧化-生化工艺处理邻氯苯酚废水,通过UV-Fenton氧化预处理,可以去除大部分的邻氯苯酚,将大分子降解成低分子脂肪烃化合物,从而提高了废水的可生化性.对于CODcr1000mg/L左右,邻氯苯酚浓度为625mg/L的废水,H2O2为1/4Qth理论投加量时,经过UV-Fenton-生化组合处理工艺处理,CODcr去除率可达到64.4%,邻氯苯酚去除率可达94.6%.An appartus for the UVFentonBiochemistry decomposition of orthochlorophenol wastewater was established. Wastewater was treated by ultraviolet light/hydrogen peroxide/fenton's reagent oxidation (UV/H2O2/Fe2+) method. Through the pretreatment of orthochlorophenol wastewater by UVFenton system, it will be easy to treat by using biochemistry methods. At the same time, most of orthochlorophenol will be degraded. When the original concentration of CODcr was 1 000 mg/L and orthochlorophenol was 625 mg/L, the wastwater reacted with H2O2 at 25 % CODcr,in(1/4Qth) and the ratio of Fe2+∶ H2O2 being 1∶20, through the treatment of UVFentonbiochemistry system, 64.4 % CODcr and 94.6 % of orthochlorophenol were moved.
