摘要:针对某热电厂石灰石-石膏法烟气脱硫工艺废渣处理系统产生的脱硫废水，采用化学沉淀工艺进行处理，经过一年的运行发现其技术可靠、稳定，对悬浮物、COD、氟化物、汞、硫酸盐的去除率分别达到99.5%、98.3%、87.5%、99.8%、85.6%，对应出水浓度分别为54、20、9.6、0.04、980 mg/L，出水水质满足并优于《火电厂石灰石-石膏湿法脱硫废水水质控制指标》（DL/T 997—2006）的要求，且电费和药剂费合计仅为6.65 元/m3。
Abstract:The desulfurization wastewater generated by the waste residue treatment system of the limestone-gypsum flue gas desulfurization (FGD) process in a thermal power plant is treated by chemical precipitation process. After one year of operation, the technology is found reliable and stable. The removal rates of SS, COD, fluoride, mercury and sulfate reached 99.5%, 98.3%, 87.5%, 99.8% and 85.6% respectively, and the corresponding effluent concentrations were 54 mg/L, 20 mg/L and 9.6 mg/L, 0.04 mg/L, 980 mg/L. Finally, the effluent quality of the system is no less than the requirements of Discharge Standard of Wastewater from Limestone?gypsum Flue Gas Desulfurization System in Fossil Fuel Power Plants (DL/T 997-2006). In addition, the total cost of electricity and chemical is only 6.65 yuan/m3.
