改性粉煤灰吸附处理焦化厂含酚废水的研究

Study on the Treatment of Phenolic Effluent from Coking Plants with Modified Fly Ash

介绍了改性粉煤灰吸附剂的制备方法,研究了pH值和废水的流速对吸附的影响,探讨了改性粉煤灰处理焦化厂含酚废水的可行性。结果表明,在室温、pH值为2.0～2.5及废水流速在8mL/min～10mL/min的条件下,酚、SS、COD和色度的去除率分别达到98.7%、97.3%、94.4%和96.9%,而且处理费用低。

The preparation method of modified fly ash as a sorbent was introduced, and the impact of the pH value and velocity of the wastewater on sorption capacity studied, besides, the feasibility for treatment of phenolic effluent from coking plants with modified fly ash was also discussed. The results showed that under 2.0～2.5 pH value, 8～10 mL/min flow rate of the wastewater, the removal rate of phenols, SS, COD and color is 98.7%, 97.3%, 94.4% and 96.9% respectively at room temperature. The operation cost is low.
