摘　　要：采用以焦粉为滤料的UBAF反应器对经过二级生化处理后的焦化废水进行深度处理,出水中COD和NH3-N含量分别为99.3～122.3mg/L和43.3～52.1mg/L,去除率分别为36.7%～48.6%和21.5%～34.8%。在极板间距为1cm,电解时间为120min,电解电压为15V的最佳条件下,采用UBAF-复极性三维电极反应器对经过二级生化处理后的焦化废水进行深度处理,出水中COD和NH3-N含量分别为31.3和13.7mg/L,去除率分别为83.3%和79.4%,COD和氨氮指标低于《钢铁工业水污染物排放标准》GB13456-1992中的焦化一级排放标准。Using UBAF （Up Biological Aerated Filter） process,the concentration of COD and NH3-N can be up to 99. 3～122. 3 mg/L and 43. 3～52. 1 mg/L,and the removal efficiency can be up to 36. 7% ～48. 6% and 21. 5%～34. 8% respectively. Setting the polar plate＇s distance at 1 cm,the electrolytic time at 120 min and the cell voltage at 15 V,treated by UBAF bipolar three-dimensional electrode process,the concentration of COD and NH3- N can be up to 31. 3 and 13. 7 mg/L,and the removal efficiency can be up to 83. 3% and 79. 4% respectively. The coking wastewater effluent can meet the Class 1 emission standard of Discharge Standard of Water Pollutants for Iron and Steel Industry in China.
