Abstract:

As a type of quaternary ammonium compounds, didodecyl dimethyl ammonium chloride (DADMAC C12) was frequently detected in wastewater treatment plants. Here, floc-based sequencing batch reactor (FSBR), granule -based SBR (GSBR) and biofilm SBR (BSBR) were fed with 0.5, 5 and 10 mg/L of DADMAC C12 for 120 d. Compared with floc sludge and granule sludge, biofilm had the strongest ability to resist the impact of DADMAC C12. Notably, in both FSBR and GSBR systems, 5 mg/L DADMAC C12 promoted denitrification sludge to become hydrophobic and compact due to an increase in alpha-Helix/(beta-Sheet+Random coil), consequently enhancing sludge granulation. Besides,high concentration of DADMAC C12 generally increased the abundances of MGEs in three denitrification systems, except extracellular MGEs in water. The variation of efflux pump ARGs was basically consistent with that of MGEs. The stimulation of DADMAC C12 also increased significantly the abundance of extracellular antibiotics deactivation ARGs in water in three denitrification systems. Besides, DADMAC C12 induced co-selection among various ARGs and promoted the proliferation and spread of sulfonamide ARGs in water.
