On the basis of invest igating t he influence of EG dosage, adsorpt ive t ime and adsorptive temperature on the disposal efficiency, an adsorpt ion met hod to fa- t her industrial w ast ew at er of pharmic int ermediates produced by coal tar as raw mat erial w as set up . T hen, under the opt imal adsorpt ion condit ion, a new combinat ion method of adsorption and oxidat ion to fat her the industrial w astew ater w as set up on the basis of investigat ing the inf luence of hydrogen peroxide dosage on t he disposal ef- f iciency. T he ex periment al results showed t hat t he disposal efficiency to be disposed once could attain 50 . 0 % w hen EG dosage, the adsorpt ive t ime, t he adsorptive temperature and hydrogen peroxide dosage were 0 . 10 g, 20 min, 20~ 40 and 0. 60 m L. Key words: industrial w astew ater; exf oliat ed graphit e; COD; disposal efficiency .
