摘　　要：本文介绍了按木化机浆废水的污染物指标,探讨了按木化机浆废水生物处理和深度处理性能,开展了光催化氧化-生物降解直接耦合法(ICPB)对其好氧脱毒处理过程的影响及机理研究。结果表明,桉木化机浆废水的生化处理效果较差;ICPB法中光催化氧化和微生物降解具有良好的协同作用,可显著提高按木化机浆废水好氧处理效果并降低深度处理过程中芬顿试剂用药量,好氧处理过程中废水CODcr去除率由46.66%提高至74.34%;ICPB体系中微生物的多样性和丰富度增加,降解芳香族化合物的优势菌种显著增加。In this paper,the pollutant indexes,biological and advanced treatment properties of eucalyptus chemi-mechanical pulp wastewater were introduced.The aerobic detoxification process and mechanism of the wastewater through intimately coupled photocataly-sis and biodegradation method(ICPB)was studied.The results showed that the biochemical treatment effect of eucalyptus pulping wastewater was poor.ICPB method can significantly improve the aerobic treatment effect of eucalyptus chemi-mechanical pulp wastewater and reduce the dosage of Fenton reagent in the advanced treatment process,which is due to the synergistic effect between photocatalytic oxidation and microbial degradation.The COD_(cr) removal of wastewater in the aerobic treatment process increases from 46.66%to 74.34%.The diversity and richness of microorganisms in ICPB system increased,and the dominant bacteria degrading aromatic compounds increased significantly.
