| Zusammenfassung: | A process for reclaiming the waste mother liquid of H acid from dye factory includes such steps as recovering sodium sulfate from said waste mother liquid, preparing water-coal slurry from coal and residual waste mother liquid in weight ratio of (1-2):(1-8) and adding lime stone to regulate its pH value greater than or equal to 7. The resultant water-coal slurry can be used as part or all of the fuel of boiler. Its advantages include less investment, low cost and high safety and feasibility. |
