| 摘 要： | 为了优化臭氧-生物活性炭(O3-BAC)工艺运行条件,提高出水水质,该文以O3-BAC工艺现场试验为基础,比较上向流/下向流生物活性炭滤池对污染物质的去除效果。试验结果表明:上向流BAC出水耗氧量平均1.6mg/L,去除率38%左右,高于同期下向流BAC 10%。出水浊度0.55散射浊度单位(NTU),比下向流BAC出水高15%,30d内水头损失平均维持在40cm,有效延长了反冲洗周期。在按设计参数运行的试验中也取得了较好的效果,说明上向流BAC相比传统的下向流BAC具有一定的优势。

| Abstract: | The flow in ozone-biological activated carbon(O3-BAC) filters was analyzed to investigate the effect of upflow and downflow BAC filters for contaminant removal to optimize the operating conditions and improve drinking water quality.The results show that the upflow BAC filter effluent CODMn is 1.6 mg/L with a 38% removal ratio of sand filter effluent CODMn,10% higher than that of the down-flow BAC filter.The upflow BAC filter’s effluent turbidity is 0.55 NTU,which is 15% higher than that of the down-flow BAC filter.The average head loss remained at 40 cm for 30 days,which effectively extends the backwash cycle.Satisfactory results were obtained using the design parameters to run the device,which means,that an upflow BAC has some advantages over the traditional downflow BAC. |
