采用离子交换树脂吸附去除炼化废水中的SO_4~(2-),以静态吸附法对比凝胶型树脂和大孔型树脂的性能,并进一步探究最优树脂的SO_4~(2-)吸附和脱附再生性能。结果表明,大孔型树脂较凝胶型树脂在复杂水质情况下性能更稳定,最优树脂为D201树脂,有较稳定的饱和吸附容量和较好的吸附脱附性能。 Ion exchange resin was used to remove SO 4 2- in the refinery wastewater and the static adsorption method was used to compare the properties of gel resin and macroporous resin. Desorption regeneration performance. The results show that the macroporous resin is more stable than the gel resin in complex water quality. The optimum resin is D201 resin, which has a more stable saturated adsorption capacity and a better adsorption and desorption performance.
