【摘要】 对褐煤焦渣吸附、Fenton试剂氧化联合处理鲁奇炉煤气废水作了研究,分别考察了焦渣、H2O2、Fe2+投加量以及pH值、温度、时间等因素对COD去除率的影响,确定了最佳处理条件。实验结果表明,可使废水的COD值由1 880 mg/L降至90 mg/L,去除率达到95.16%,符合国家一级排放标准。同时,采用吸附-氧化法联合处理,不仅降低了直接使用Fenton试剂氧化的处理成本,而且为焦渣开辟了新的用途。更多还原

【Abstract】 The union treatment of Lurgi gasifier coal gasification wastewater with lignite pyrolysis char adsorption and Fenton reagent catalytic oxidation was studied.Parameters such as the dosage of H2O2 or Fe2+,pH value,treatment time and temperature were investigated in terms of the removal of COD.The results show that COD value is reduced from 1 880 mg/L to 90 mg/L and the removal rate of COD is 95.16%.Meantime,the union treatment of adsorption and oxidation not only reduces the cost by Fenton reagent direct oxidation,but also develops a new purpose of char.更多还原
