摘要
采用螯合沉淀法,选用重金属离子捕集沉淀剂DTCR,对某燃煤电厂的烟气脱硫废水进行了重金属处理,结果表明,出水总Hg为0.004mg/L,总Cd为0.003mg/L,总Pb为0.013 mg/L,总Ni为0.02 mg/L,总Cu为0.012mg/L,总Zn为0.034 mg/L,达到《污水综合排放标准》(GB8979-1996)要求。
Desulfurization wastewater containing heavy metals of coal - fired power plants was treated by chelation- precipitation process. The heavy metal capturing and precipitation agent was used to treat wastewater. The results showed that the effluent quality could reach the integrated wastewater discharge standard （ GB8979 - 1996） , with Hg 0. 004mg/L, Cd 0. 003mg/L, Pb 0. 013 mg/L, Ni 0. 02 mg/L, Cu 0. 012mg/L,Zn 0. 034 mg/L.
