【摘要】 研究了火力发电厂采用干法除尘的冲灰和输送粉煤灰水（ｐＨ＝１０．０～１０．５）对烟道气中ＳＯ２的脱除作用，同时比较了相同ｐＨ的ＮａＯＨ，Ｃａ（ＯＨ）２吸收液和电厂粉煤灰水的脱硫效果。实验结果表明，在上述三者的ｐＨ值相同时，粉煤灰水的脱硫效果最好。因此，验证了粉煤灰水是理想的吸收液，为以废治废提供了可行性的方法和依据更多还原

【Abstract】 In this subject,removing SO 2 in flue gas by using the water of washing and transporting coal ashes of power plant(pH=10.0～10.5) has been emphatically studied.During experiments,the results of removing SO 2 in flue gas by using NaOH and Ca(OH) 2 and the water of coal ash as absorbents have been studied at the same time.The experiments show that when three absorbents have the same pH,the water of coal ash has the highest efficiency of removing SO 2.Therefore,it has been proved that the water of coal ash is the ideal absorbent.This study has provided a favorite method for using waste water treating waste gases.更多还原
