摘要:

脱硫废水水量的确定不仅关系到烟气超低排放处理系统的运行,而且直接影响到脱硫废水处理工艺的选择以及投资、运行成本。脱硫废水水量的确定需要考虑脱硫浆液氯离子含量、石膏品质控制、脱硫工艺水水质、机组运行的煤质及烟气温度等多个因素。对影响脱硫废水水量的因素进行了深入分析,提出了减少脱硫废水水量的措施。

Abstract:

Determination of the amount of desulfurization wastewater not only matters the operation of flue gas ultralow emission equipments but also directly affects the investment and running costs of the wastewater treatment. However, many factors could effect the amount of desulfurization wastewater, such as Cl- concentration in the desulfurization slurry, gypsum property control, desulfurization process water quality as well as coal type, flue gas temperature, etc. All these factors were analyzed, and the wastewater reduction ways were also proposed.
