文摘

PCDD/Fs were determined in non-wood pulp mill while using enzyme-aided bleaching. Increases of PCDD/F levels were found when using enzyme-aided bleaching process. Formation of OCDD was promoted by xylanase during non-wood pulp bleaching. The effectiveness of enzyme on PCDD/F reduction needs further evaluation.
