| description | The invention relates to a desulfurization waste liquid treatment system and method, and belongs to the field of wastewater treatment. The method comprises the following steps: removing cyanides and organic matters in the desulfurization waste liquid in a multi-stage manner, and removing sulfate radicals and metal ions through chemical precipitation to generate a NaCl solution; and further electrolyzing the NaCl solution to generate NaClO3. According to the treatment method, the desulfurization waste liquid can be effectively treated, and comprehensive utilization of resources can be achieved.
本发明涉及一种脱硫废液的处理系统及方法，属于废水处理领域。该方法包括多级去除脱硫废液的氰化物和有机物，再通过化学沉淀去除硫酸根和金属离子，生成NaCl溶液；再进一步电解NaCl溶液，生成NaClO3。此处理方法既能有效的处理脱硫废液，又能做到资源的综合利用。 |
