AB  - Biochar was utilized to intensify constructed wetland (CW) for further organic 
      and nitrogen removal from secondary wastewater. Four sets of non-aerated biochar 
      amended vertical flow CW (VFCW) were developed to investigate the synergistic 
      effects of biochar and microbes on pollutant removal. Results showed that the 
      average COD and nitrogen removal efficiencies of VFCW1 (with 1% w/w biochar with 
      microbe and plants) achieved 89.1 +/- 5.6% and 90.2 +/- 3.1% respectively, and their 
      corresponding removal rates of 10.2 +/- 0.8 mg-COD/(m(3).d) and 
      3.57 +/- 0.3 mg-TN/(m(3).d) which were 35 and 52.3% higher than control. The 
      biochar's dissolved organic carbon release in VFCWs indicated that water and 
      acidic media portray the optimum conditions for nitrogen removal. The 16S RNA 
      gene sequencing analysis indicated that in the biochar-amended VFCWs, bacterial 
      phylum Proteobacteria (24.13-51.95%) followed by Chloroflexi (5.64-25.01%), 
      Planctomycetes (8.48-14.43%), Acidobacteria (2.29-11.65%) were abundantly 
      enhanced. Conclusively, incorporating biochar in non-aerated VFCWs is an 
      efficient technique for enhancing nitrogen removal from secondary effluent.
