摘　　要：试验采用焦煤作为吸附剂,对煤化工反渗透浓缩废水进行吸附处理。结果表明,焦煤可以显著吸附废水中的有机物,焦煤用量为80 g/L时,总有机碳(TOC)、吸光度(UV_(254))与色度的去除率分别为70.23%、70.21%和67.51%;吸附过程符合Langmuir等温吸附模型,动力学符合准二级动力学模型。The experiment uses coking coal as an adsorbent to adsorb and treat coal chemical reverse osmosis concentrated wastewater.The results show that coking coal can significantly adsorb organic matter in wastewater,when the dosage of coking coal is 80 g/L,the removal rates of total organic carbon(TOC),absorbance(UV_(254)),and chromaticity are 70.23%,70.21%,and 67.51%,respectively;the adsorption process follows the Langmuir isotherm adsorption model,and the kinetics follow the quasi second order kinetic model.
