AB  - The degradation of persistent organic pollutants (POPs) in the simulated 
      wastewaters was investigated by Fe-C micro-electrolysis system. With phenanthrene 
      (PHE) and 2,4-dichlorophenol (2,4-DCP) as target pollutants, different 
      iron-carbon (Fe-C) micro-electrolysis systems have been established. The effects 
      of initial pH, Fe/C mass ratio, and intake air flow on the degradation and 
      mineralization of PHE and 2,4-DCP were studied. At the initial pH of 5.0, Fe/C of 
      1.5:1, and an aeration flow rate of 1.5 L/min, after 120 min of reaction, the 
      removal efficiency of FHE and COD was 94.3% and 73%, respectively. Under the 
      conditions of initial pH is 3.0, Fe/C is 1:2, aeration flow rate of 1.5 L/min, 
      and reaction time of 90 min, the best removal efficiency of 2,4-DCP can be 
      obtained in the Fe-C micro-electrolysis system as 97% and COD removal efficiency 
      can reach 76%. The results of kinetic studies show that the Fe-C 
      micro-electrolysis process of PHE and 2,4-DCP follows pseudo-first-order 
      kinetics. Commercial activated carbon (AC) was used for comparison under the same 
      condition. The results indicated that the removal rate of organic pollutants and 
      chemical oxygen demand (COD) of Fe-C micro-electrolysis were superior to that of 
      AC. Analyze the structure of iron after reaction by SEM and XRD. The degradation 
      pathway and mechanism for PHE and 2,4-DCP were proposed based on LC-MS analyses 
      of treated wastewater.
