  • 摘要: 采用曝气铁炭微电解工艺对焦化废水进行了深度处理。结果表明，在活性炭、铁屑和NaCl投加量分别为10g/L、30g/L和200mg/L的条件下反应240min，出水COD去除率在30%～40%；酸性条件可以进一步提高COD去除率；微电解可以去除原生化出水中的难降解有机物，出水物质的分子量主要集中于2000Da以下，以脂类和烃类化合物为主；出水的可生化性有了大幅度提高，BOD5/COD由0.08增加到0.53。实验结果表明，铁炭微电解是深度处理焦化废水的一种有效工艺。
    Abstract: Advanced treatment of coking wastewater by ironcarbon microelectrolysis process with aeration was studied. It was found the COD removal efficiency reached 30%～40% with 10 g/L active carbon 30 g/L iron material and 200 mg/L sodium chloride after 240 min reaction. Low pH condition improved the COD removal efficiency. The microelectrolysis process can remove the refractory organic compounds. The dominant contaminants in the effluent are ester and alkyl compounds, which have the low molecular weight less than 2000 Da. The process enhanced the biodegradability of the effluent evidently, for BOD5/COD ratio increased from 0.08 to 0.53. Therefore, ironcarbon microelectrolysis process is an effective means for advanced treatment of coking wastewater.
