Scholarcy highlights

  • Constructed wetland and A2/O followed by MBR, have high efficiency for antibiotic removal
  • Aim of this study was to provide an up-to-date assessment of the heavy metals and antibiotics in reclaimed water in Chengdu, China. 3 sewage treatment plants and 1 constructed wetland were first taken as the research objects
  • This is because macrolides were wrapped in human feces, whose concentration increased as feces disperse and hydrolyze
  • Compared with Cyclic Activated Sludge System and Anaerobic-Anoxic-Oxic process, the average removal rate of antibiotics from the A2/O accompanied by Membrane Bio-Reactor and CW was higher
  • It was assessed that the heavy metals and antibiotics studied did not pose a carcinogenic or non-carcinogenic risk to human health
