摘要
综述了燃煤电厂脱硫废水处理及综合利用新技术,可采用混凝沉淀法、离子交换法或吸附法除去废水中的痕量重金属离子(如汞离子、铬离子等),然后采用膜分离技术浓缩酸性废水,减少重金属污染物的排放,循环利用水资源。
In this paper, new techniques for the treatment and comprehensive utilization of wastewater from desulfurization processes in coal-fired power plants are summarized. Coagulation precipitation method, ion- exchange or adsorption process is used to remove the trace metal ions, e.g., mercury ions and chromic ions. Thereafter, membrane technique is used to concentrate the wastewater to the industrial dilute acid level. This will not only reduce the heavy metal discharge and recycle the water source, but also make some profits in the use or sale of the dilute acids.
