摘要

  • 摘要: 研究了臭氧氧化、生物过滤、沸石吸附对微污染水中有机物的不同处理效果和组合工艺的竞争、协同效果。结果表明：对于CODMn为6.30～7.20 mg/L的原水，在臭氧投加量为2.1 mg/L，接触时间为15 min时, CODMn的去除率可达10.8%；沸石吸附对CODMn的平均去除率为11.5%，生物沸石对CODMn的平均去除率为32.3%。臭氧沸石工艺的CODMn平均去除率为15.6%，小于工艺组成单元的单独去除率的加和，各单元在有机物处理上存在竞争关系。臭氧-生物沸石工艺的CODMn平均去除率为45.5%，大于臭氧氧化和生物过滤独立单元去除率的加和，各单元之间为协同作用关系，因此宜采用臭氧-生物沸石工艺处理有机微污染水体。
    Abstract: Ozonation, biological filtration, zeolite adsorption and combined processes were employed individually to remove organic matters, the competition and synergy effects were analyzed. CODMn in the raw water was 6.30～7.20 mg/L. The average CODMn removal rate was 10.8%, when the O3 dosage was 2.1 mg/L and the contact time was 15 min, while the average removal rate was 11.5% by zeolite and 32.3% by biological zeolite separately. By ozone-zeolite, the average removal rate was 15.6%, which was less than the removal rate of the combination of separate unit,every separate unit was competitive in the removal of CODMn. The average removal rate by ozone-biological zeolite was 45.5%, which was more than that of the combination of separate unit. Thus, every separate unit was synergistic in the removal of CODMn. It is appropriate to use ozone-biological zeolite to treat organic micro-polluted water.
