摘要

       用微波-酸（MW-H）、微波（MW）和微波-H2O2-碱性（MW-H2O2）对污泥厌氧消化（AD）过程中抗生素抗性细菌（ARB）和抗生素抗性基因（ARGs）的去向进行了研究。 ) 预处理。 结果表明，联合MW预处理尤其是MW-H预处理可以有效降低ARB浓度，并且大多数ARG浓度在预处理过程中趋于减弱。 随后的 AD 显示出明显的 ARB 去除，但大多数 ARG 在 AD 后富集。 在整个污泥处理过程中，只有tetX的浓度保持持续下降。 在预处理和AD期间，总ARGs浓度与16S rRNA显着相关。 与未经预处理的污泥相比，MW 和 MW-H2O2 预处理污泥的 AD 表现出略好的 ARB 和 ARGs 还原效率。

       The fate of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) were investigated during the sludge anaerobic digestion (AD) with microwave-acid (MW-H), microwave (MW) and microwave-H2O2-alkaline (MW-H2O2) pretreatments. Results showed that combined MW pretreatment especially for the MW-H pretreatment could efficiently reduce the ARB concentration, and most ARG concentrations tended to attenuate during the pretreatment. The subsequent AD showed evident removal of the ARB, but most ARGs were enriched after AD. Only the concentration of tetX kept continuous declination during the whole sludge treatment. The total ARGs concentration showed significant correlation with 16S rRNA during the pretreatment and AD. Compared with unpretreated sludge, the AD of MW and MW-H2O2 pretreated sludge presented slightly better ARB and ARGs reduction efficiency.
