Abstract

Paper making Black Liquor (BL) difficult to treat. Acid-producing White Rot Fungus (AWRF) was used to regulate the pH and convert the lignin in paper making BL into forms more easier to degrade. Then the BL is put into further treatments of anaerobic hydrolysis, contact oxidation and internal electrolysis processes. Average removal rates of COD and colour are up to 98.04% and 97.68% respectively which have been obtained in case the inlet COD was 10,000 mg/L and colour was 6000 C.U, at temperature 25~29°C and retention time 3 days, 4 hours, 24 hours and 30-40 min in sequence of a continuous operation for 20 days.
