摘要:

根据HPF法脱硫的反应机理及生产实践,探讨了用脱硫液中SCN-的平衡来确定脱硫废液外排量,控制硫代硫酸铵的浓度在60~80g/L,硫氰酸铵在120~140g/L,脱硫系统外排废液量控制在30~35m3/d较为适宜。

Abstract:

This paper introduces the determination for desulfurized liquor discharge volume with SCN- balance according to the HPF reaction mechanism and actual production,with optimized results,such as ammonium thiosulfate around 60~80g/L,ammonium thiocyanate around 120~140g/L and that the volume of the discharged desulfurized liquor can be controlled at 30~35m3/day.
