AB  - This study investigated a novel magnesium carbon micro-electrolysis (Mg-C ME) 
      system for strengthening the removal of phenolic compounds in wastewater. The 
      effects of the Mg/C mass ratio, aeration intensity, initial pH and reaction time 
      on the degradation of three phenolic compounds and the COD removal efficiency in 
      the simulated wastewater were evaluated using one-factor-at-a-time (OFAT) method. 
      The optimum values obtained for the Mg/C mass ratio, aeration intensity, initial 
      pH and reaction time were 3:1, 4.0 L/(L.min), 5.0 and 2.5 h, respectively. The 
      experimental removal rates of catechol, resorcinol, and phenol, under the 
      mentioned conditions, were obtained to be 95.6%, 71.5%, and 48.8%, respectively. 
      Meanwhile, the COD removal rates were 63.8%,44.7%,34.0%, respectively. Moreover, 
      experiments were designed and analyzed based on the box-based designing response 
      surface (BBD-RSM) method. According to the results, the Mg/C mass ratio was the 
      most significant variable showing incremental effect on the removal efficiency of 
      catechol in a way that maximum removal efficiency of catechol was achieved in 
      Mg/C mass ratio of 3.23:1. The validation experiments showed that the maximum 
      removal efficiency of catechol was 96.24% under optimization conditions. 
      Resorcinol degradation characteristics analysis indicated that the Mg-C ME system 
      performed a key function in phenolic compounds elimination. Results showed that 
      the Mg-C ME has a considerable capability in removing the phenolic compounds and 
      COD. Thus, it could be considered as an efficient pretreatment choice for 
      treating phenolic wastewater in the future.
