前期试验研究和采用X衍射仪(XRD)表征改性粉煤灰和炭化秸秆结构比较发现,6 mol.L-1的NaOH改性粉煤灰和无氧下650℃炭化的秸秆吸附性较好。通过它们联合吸附吡唑酮废水中的铵盐试验结果表明,最佳吸附工艺为炭化秸秆与改性粉煤灰的质量比为1.25:3.0,吸附温度为50℃,振荡频率120 r.min-1,饱和吸附时间4 h,吡唑酮废水中铵盐去除率为95.31%以上,表明炭化秸秆与改性粉煤灰是一种很好的吡唑酮废水的处理剂。
Previous experimental studies and X-ray diffraction (XRD) characterization of modified fly ash and carbonized straw structure comparison found that 6 mol.L-1 of NaOH-modified fly ash and carbonized straw at 650 ℃ under anaerobic better adsorption . Through their combined adsorption of ammonium pyrazolone wastewater test results show that the best adsorption process for the carbonized straw and modified fly ash mass ratio of 1.25: 3.0 adsorption temperature of 50 ° C, the oscillation frequency of 120 r.min- 1, the adsorption time of saturated 4 h, ammonium pyrazolone wastewater removal rate of 95.31% or more, indicating that carbonized straw and modified fly ash is a good pyrazolone wastewater treatment agent.
