| 摘 要： | 采用高温和酸分别对粉煤灰进行改性,对比了改性后的粉煤灰对焦化废水深度处理的效果,确定了最佳工艺条件。结果表明,焦化废水COD135~170mg/L,NH3-N 96~135mg/L,体积150mL,pH值5,改性粉煤灰投加量25g,粒径100~160目,吸附时间60min,石灰量0.25g,高温改性粉煤灰对焦化废水COD和氨氮的去除率分别达到了85.2%和89.6%,而酸改性粉煤灰对焦化废水COD和氨氮的去除效果劣于高温改性粉煤灰,去除率分别为78.3%和82.7%。

| Abstract: | The authors of this paper modified fly ash with high temperature and acid respectively, studied the advanced treatment effect of coking wastewater with modified fly ash and finally acquired the optimum technological conditions. e results show that COD of coking wastewater is 135~170 mg/L, NH3 is N 96~135 mg/L, the volume is 150 mL, pH value is 5, the amount of added modified fly ash is 25 g, the particle size is 100 to 160 mesh, the adsorption time is 60 min, the quantity of lime is 0.25 g, the removal rates of the coking wastewater COD and ammonia nitrogen with high-temperature modified fly ash reach 85.2% and 89.6% respectively, and the removal of them with acidly modified fly ash is less efficient that that of high-temperature modified fly ash and its removal rates are 78.3% and 82.7%, respectively. |
