以升流式柱状炭滤池和破碎炭滤池为研究对象,探讨不同形式炭滤池的净水效果、水头损失及对后续工艺的影响。结果表明,柱状炭滤池对浊度的截留量较少,不存在炭层积泥板结现象,对NH_3~-N去除率可达90%以上,对有机物也有一定去除作用,水头损失较低,初滤水浊度不高;而破碎炭滤池虽然基本不截留浊度,有机物去除效果较好,但对NH_3~-N去除率较低,水头损失较高,初滤水浊度较高。
Taking the upflow columnar carbon filter and the crushing carbon filter as the research object, the effects of different types of carbon filters on water purification, head loss and subsequent process were discussed. The results showed that the columnar charcoal filter retained less turbidity, there was no phenomenon of carbonaceous sediment compaction, the removal rate of NH_3 ~ -N was more than 90%, the removal of organic matter was also removed, the head loss was low, The turbidity of the initial filtration water was not high. Although the turbid carbonation filter basically did not retain turbidity, the removal efficiency of organic matter was better, but the NH3-N removal rate was lower, the head loss was higher and the initial filtration turbidity was higher.
