摘　　要：采用串联两级活性炭吸附装置处理某煤化工两级反渗透RO2浓排水(COD>500 mg/L,Cl^(-)>10000 mg/L,TDS>20000 mg/L)。结果表明,一、二级吸附柱中装填煤质柱状活性炭(碘值1000 mg/g)32 kg(70.7 L),一级进水0.7 L/min,出水全部进入二级,处理量7~10 m^(3)/d时,出水COD平均为114 mg/L,达到<115 mg/L的要求。The two-stage reverse osmosis RO2 concentrated drainage(COD>500 mg/L,Cl^(-)>10000 mg/L,TDS>20000 mg/L)of a coal chemical industry was treated with a series two-stage activated carbon adsorption device.The results show that 32 kg(70.7 L)of coal columnar activated carbon(iodine value 1000 mg/g)is filled in the first and the second stage adsorption columns,and the water enters the second stage with 0.7 L/min in the first stage.When the treatment capacity is 7~10 m^(3)/d,the effluent COD is 114 mg/L on average,reaching the requirement of less than 115 mg/L.
