真空碳酸钾脱硫废液预处理的研究与应用

Abstract

Abstract:

High content of cyanides and sulfides in waste liquid produced with vacuum potassium carbonate desulfurization process would easily affect waste water treatment system in the process of production.The removal rate of cyanide and sulfide are 95% plus and 99% plus respectively after pretreatment of waste desulfurizer liquid by IPE-DCN process.The sludge from the pretreatment is used for coal blending for cokemaking,and the clear liquid after pretreatment could reduce the impact on the water treatment system.

Key words:

"> Vacuum potassium carbonate desulfurization, Waste liquid pretreatment, Cyanides, , Sulfides, Coking wastewater

CLC Number:

X784
