| Abstract: | 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. |
| Keywords: | coal-fired power plant desulfurization process wastewater treatment comprehensive utilization |
