摘　　要：针对某水厂采用的中置式高密度沉淀池—H2O2/O3—生物活性炭—砂滤组合工艺,介绍了不同时期单独O3和H2O2/O3催化氧化技术对组合工艺处理效果的影响,同时比较了不同投加量对出水水质的影响,分析了组合工艺的运行效果。运行结果表明:O3和H2O2/O3能有效分解水中大分子有机物,臭氧投加量为1～2mg/L时,组合工艺对有机物的去除率随投加量的增加而增加,投加H2O2/O3比单独投加O3去除效果稍好。较高的温度有利于活性炭和砂滤的生物降解作用。Aiming at the combination of centrally-set high concentration sedimentation tank- H2O2/O3-BAC-sand filter applied in a water treatment plant, this paper introduced the impacts of only O3 and H2O2/03 catalytic oxidation on this combination in different times, studied the impacts of different dosages on water quality, and analyzed the operation effects of this combined process. The operation results showed that O3 and H2O/O3 could decompose the large molecular organic matters in water; when the O3 dosage was 1 to 2 mg/L, the removal efficiency of organic matters in this combined process would increase with the increase of dosage; the effect of adding H2O2/O3 was better than adding only O3. Comparatively high temperature would be helpful for the biological degrading effects in biological activated carbon and sand filter.
