AbstractPhthalic acid esters (PAEs), especially dibutyl phthalate (DBP) pollution in the environment, have attracted worldwide attention. Four Phragmites australis-based, mesocosm-scale vertical flow constructed wetlands (VFCWs) with different hydraulic loading rates (HLRs) were operated for one year to study the removal efficiency and mechanisms of DBP in the reclaimed water. The average removal efficiencies for DBP were 93.77 +/- 3.27%, 94.9 +/- 2.60% and 97.0 +/- 3.00% in the VFCWs under HLRs of 0.33, 0.22 and 0.11 m/d, respectively. DBP can be accumulated and degraded by wetland plants and its concentration in the roots (0.256-8.45 mg/kg) were higher than in the leaves (0.243-0.482 mg/kg). The concentrations of primary and secondary metabolites mono-n-butyl phthalate (MBP) and phthalic acid (PA) were 0.142 -2.35 mg/kg and 0.113-0.545 mg/kg respectively in the plant tissues. The concentrations of DBP were 38.2-271 mu g/kg in the substrates. Mass balance for DBP indicates that the estimated plant uptake and substrate adsorption of total DBP is negligible. This suggests that biodegradation and other process are the primary pathways for DBP removal in VFCWs. The results of 16S rDNA and ITS rDNA high-throughput sequencing indicated that both bacterial and fungal community diversity decreased with the exposure of DBP. Janthinobacterium, Flavobacterium and Curvularia genera may be the main participants in the biodegradation of DBP in the CWs. (C) 2019 Elsevier Ltd. All rights reserved.
