| Abstract: | The difficult degradation polyvlhyl alcohol (PVA) desizing wastewaster was treated by using combined anaoxic denitrification-contact oxidation system with the design scale of 3 000 m3/d. After treatment, the removal rates of CODcr, BOD5, SS and chroma reached 96.3%, 94.8%, 90.2% and 85.0% respectively. All indicatrixes of the, effluent were up to the national discharge standard grade of GB4287-92. |
