摘要:
分别采用“收集池+混凝沉淀+水解酸化+巴顿甫生化池+二沉池+异相Fenton氧化+稳定池+沉淀池+曝气活性炭生物滤池”（工艺1）及“收集池+异相Fenton氧化+稳定池+沉淀池”（工艺2）对医药化工园区工业废水进行处理，并重点考察异相Fenton氧化分别作为深度和预处理工艺对COD的去除效果。结果表明，工艺1中的异相Fenton氧化出水COD为（57.50±5.72） mg/L，去除率为（56.69±3.11）%，整个工艺出水COD达到了《城镇污水处理厂污染物排放标准》（GB 18918—2002） 一级A标准的限值要求；工艺2中的异相Fenton工艺出水COD为（107±22.1） mg/L，去除率为（63.90±4.26）%，出水B/C为0.2，比原水有所提高。建议该园区集中处理设施主体工艺采用异相Fenton，同时针对事故工况设置异相Fenton应急预处理单元。
Abstract:
A pilot test was conducted on industrial wastewater treatment in the pharmaceutical and chemical industry park using the “collection tank + coagulation sedimentation + hydrolysis acidification + Bardenpho + secondary sedimentation tank + heterogeneous Fenton oxidation + stabilization tank + sedimentation tank + aerated activated carbon biofilter” (process 1) and “collection tank + heterogeneous Fenton oxidation + stabilization tank + sedimentation tank”(process 2). The removal efficiency of COD by heterogeneous Fenton oxidation as advanced and pretreatment process respectively was investigated. When the heterogeneous Fenton oxidation was used for advanced treatment unit, effluent COD was (57.50 ± 5.72) mg/L with a removal rate of (56.69 ± 3.11)%. The effluent COD of the entire process met the limit requirements of class A criteria in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB 18918-2002）. When the heterogeneous Fenton oxidation was used for pretreatment unit, the effluent COD was (107±22.1) mg/L, the removal rate was (63.90 ± 4.26)%, and the B/C ratio of the effluent was 0.2, which was slightly higher than that of the raw water. It is recommended that the main process of the centralized treatment facilities in the park adopt heterogeneous Fenton, and set up heterogeneous Fenton emergency treatment unit for accident wastewater.
