The invention discloses a kind of method of absorption method photocatalytic degradation method Combined Treatment organic dye waste water, graphite oxide/porous carbon ball compound adsorbent is prepared first；Then Cu is prepared 2 O/ graphenes/α Fe 2 O 3 Nano-tube array compound；Finally organic dye waste water is removed the gred through grid after just precipitating, supernatant is pumped into the adsorption treatment pond equipped with compound adsorbent, stirring and adsorbing handles 1 3h at 30 DEG C, then staticly settles, the supernatant after precipitation is pumped into reactor；Cu obtained above is added into reactor 2 O/ graphenes/α Fe 2 O 3 Nano-tube array compound is pumped into air as catalyst, the 16h of degradation treatment 10 under illumination condition, then the 6h of stir process 4 in the dark state, finally staticly settles, supernatant reaches discharge standard.Method percent of decolourization disclosed by the invention is high, and COD clearances are high, and cost is low. |
