类燃料电池技术处理难降解有机废水

提出了一种新型的难降解有机废水处理技术,即在常温常压下采用类燃料电池装置降解废水的同时获取电能。以甲酸为模拟废水,考察了H2O2浓度、流量、电解质浓度及渗透压对产电性能的影响。研究发现,HCOOH浓度为0.5 mol/L,H2O2质量分数为10%,流量为13.5 mL/min,两极分别加入0.1 mol/L Na2SO4,4 h库仑效率可达到13.93%。结果表明,采用燃料电池技术降解废水的同时可以获取电能,其在废水处理领域将有广阔的应用前景。

Treatment of refractory organic wastewater by similar fuel cell technology

A fuel cell technology was proposed to degrade refractory organic wastewater. This technology is innovative because at room temperature and atmospheric pressure, the reactor could accelerate the removal of formic acid and the generation of electricity. Experiments were performed to investigate the influences of hydrogen peroxide (H2O2) concentration, flow rate, and electrolyte concentration to optimize the operating parameters for the similar fuel cell. It was found that in the presence of formic acid (0.5 mol/L), H2O2 (10%), an electrolyte concentration (0.1 mol/L), and a flow rate of 13.5 mL/min, a coulombic efficiency of 13.93% could be reached during 4 h. These results showed that the similar fuel cell is promising for energy reclamation with the removal of organics and a consideration of the role of electrochemicals in wastewater treatment.
