倒置AAO＋Fenton氧化工艺处理化学工业园废水的工程应用

摘要

采用倒置AAO＋Fenton氧化工艺处理某化学工业园废水,该工业具有处理效果稳定,耐冲击负荷能力强,剩余污泥少等特点。经过2个月的试运行,出水CODCr、NH3-N质量浓度平均值分别为47 mg/L和5 mg/L,出水达到《城镇污水处理厂污染物排放标准》（GB18918-2002）中的一级A标准。%A combined process of Inverted AAO＋Fenton oxidation has been used for treating wastewater from chemical industrial area.The process is characterized by stable treatment effect,excellent compact loading resistance,and less excessive sludge.After two months of trial operation,the effluent CODCr,NH3-N concentration averages were 47 mg/L and 5 mg/L,the effluent can meet the ＂Cities Sewage treatment plant Pollutant discharge Standard＂（GB18918-2002） the level a standard.
