摘　　要：真空碳酸钾含硫废水具有极高的COD值,且含有大量硫化物,对其进行脱除处理具有重要意义。分别采用石墨电极及铁电极、铜电极作为工作电极对含硫废水进行了电化学脱除研究。结果表明,采用石墨电极的电化学直接氧化技术并不能达到理想的脱硫及COD去除效果。而采用铁电极、铜电极的电化学絮凝技术能够将真空碳酸钾含硫废水中的硫化物几乎完全脱除,但铜电极的腐蚀比较严重且COD去除效果稍差,而铁电极在电解电压为2 V、3 V时可以在损耗较低的情况下,实现近乎完全的除硫效果及COD去除效率。Sulfur-containing wastewater produced in the vacuum potassium carbonate of coking plant has high COD value and contains a large amount of sulfide.Graphite electrodes and iron and copper electrodes were used as working electrodes to explore their electrochemical remov-al properties of sulfur-containing wastewater.However,the results show that the electrochemical direct oxidation technology using graphite electrode cannot achieve an ideal desulfurization and COD removal effect.On the contrary,the electrochemical flocculation technology using iron and copper electrode can almost completely remove COD and sulfide from the sulfur-containing wastewater.Compared with the copper electrode having heavy losses,the iron electrode can achieve near-complete sulfur removal effect and COD removal efficiency under the condition of low loss with the elec-trolytic voltage of 2 V and 3 V.
