摘要:針對某熱電廠石灰石-石膏法煙氣脫硫工藝廢渣處理系統(tǒng)產生的脫硫廢水，采用化學沉淀工藝進行處理，經過一年的運行發(fā)現(xiàn)其技術可靠、穩(wěn)定，對懸浮物、COD、氟化物、汞、硫酸鹽的去除率分別達到99.5%、98.3%、87.5%、99.8%、85.6%，對應出水濃度分別為54、20、9.6、0.04、980 mg/L，出水水質滿足并優(yōu)于《火電廠石灰石-石膏濕法脫硫廢水水質控制指標》（DL/T 997—2006）的要求，且電費和藥劑費合計僅為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.
