固定化生物活性炭处理炼油废水

采用混凝-砂滤-固定化生物活性炭技术处理炼油废水,通过对浊度、COD去除率的测定评价处理效果。结果表明,在混凝剂FAPS和1%聚丙烯酰胺投加量为4 mL/L和1.0 mL/L、砂滤滤速30 mL/min、滤层高度40 cm、固定化生物活性炭柱停留时间30 min、炭柱高度40 cm的条件下,经混凝-砂滤-固定化生物活性炭技术处理后,各操作单元浊度平均去除率分别为84.17%,96.36%,97.22%,COD平均去除率分别为52.37%、62.13%,79.45%。

DISPOSAL OF REFINING WASTEWATER WITH IMMOBILIZED BIOLOGICAL DISPOSAL OF REFININ

The refining wastewater was disposed by coagulation-sand filtration-IBAC technology. The treatment effect was assessed by turbidity and COD. Results showed that under the conditions of an added dosage of FAPS and PAM was 4 mL/L and 1.0 mL/L, respectively; the speed of sand filtration was 30 mL/min and the height of sand leach column was 40 cm; the HRT of IBAC was 30 min and the height of IBAC column was 40 cm, the average removal rate of turbidity for these three operating units was 84.17%, 96.36% and 97.22%, respectively; the average removal rate of COD was 52.37%, 62.13% and 79.45%, respectively.
