| 摘 要： | 试验对比了经生物活性炭(biological activated carbon,BAC)处理后的垃圾渗滤液在水的体积不同臭氧预氧化条件相同时的COD去除效果。实验用水体积分别为0.4 L,3 L,4 L,5 L,12 L,在流量相同、臭氧氧化时间不同的条件下进行臭氧预氧化实验,对比了不同氧化时间和最佳臭氧投加量的关系。以12 L水为例,采用六组平行O3-SBR联用装置,对比不同臭氧投加量下的COD去除率。结果表明:在COD去除率的拐点处,臭氧投加量为0.19 mgO3/mgCOD时臭氧的氧化作用与生物降解作用的协同效应最佳。试验证明,对臭氧预氧化后COD去除率拐点处的研究有很大的意义。 |

| Abstract: | With the aim to inquiry the COD removal efficiency, five different volumes of leachate were acted. The experiment were compared at the same conditions. Pre-ozonation on landfill leachate was carried out. Experiment water were respectively for 400 mL, 3 L, 4 L, 5 L, 12 L. For example, volume of 12 L, six sets of identical O3-SBR combined processes under different ozone dosages were studied, the results indicated that the best COD removal rate of synergetic effect was 0.19 mgO3/ mg COD. Experimental parameters showed that researches on COD removal after the ozone oxidation turning points has great significance. |
| Keywords: | Landfill leachate Pre-ozonation Biodegradability Ozone-biological process Optimum |
