摘要： Pasteurisation pretreatment (PP) in combination with anaerobic digestion (PPAD) is one of the best ways for sterilisation of pathogenic microorganisms in manure. However, the effect of antibiotic residues in manure on PPAD has not been studied. This study investigated the function of PPAD on antibiotic removal and the effect of antibiotic on PPAD performance. Results demonstrated that chlortetracycline (CTC) and oxytetracycline (OTC) concentrations decreased from 17.236 and 183.446 to 0 and 17.348 mg/kg.TS using PPAD, respectively. PPAD for swine manure containing CTC and OTC increased methane production from 244.0 +/- 7.6 to 254.0 +/- 6.1 mL/g.VS and reduced technical digestion time (T-80) from 30 to 25 days compared with AD process. Moreover, PPAD affected only archaeal communities, whereas PP affected bacterial/archaeal communities. Thus, PPAD can be used to treat antibiotic-containing manure and reduce the negative effects of antibiotics.
