A c mbina ti n technique f ph t catalytic xidati n w ith bi chemical xidati n f r dye degradati n was studies. The result sh w ed that the c m binati n technique f bi chemical and ph t catalytic xidati n w rked very well. F r example, a 100 ppm Methyl Organge s luti n, the COD ( chemical xidati n demand) rem val and c l r rem val were 69. 67% and 22. 39% respectively after the 24 h bi l gical treatment; C nsequently, after 1h ph t catalytic xidati n, the COD rem val and c l r rem val f this s luti n w ere further increased t 84. 65% and 91. 31% respectively. It might be devel ped as an effective meth d t rem ve the rem ained c l r f dyeing effluent after traditi nal bi l gical treatment.
