主　　题：Antibiotics Tetracyclines Anaerobic composting Swine manure 

摘      要：Oxytetracycline(OTC) and tetracycline(TC) are the most common TC antibiotics used in human and veterinary *** amounts of these antibiotics in manure pose a potential threat to public and ecological health as a result of the potential for them to be released to the environment following land application of manure from animals treated with *** investigated the degradation of OTC and TC during anaerobic *** tested the effects of temperature and antibiotic concentration on degradation rates in a control and in manure spiked with *** examined changes in p H,biological degradation material(BDM),and moisture corresponding with antibiotic degradation of TCs in the swine *** showed that the OTC and TC concentrations decreased by between 68.54% and 95.50% in all nine treatments following 14 days of anaerobic composting,and the highest removal ef ficiencies were observed at an incubation temperature of 55°C and initial concentrations of 10.36 μg·g^(-1),and 5.96 μg·g^(-1) of OTC and TC,respectively,which were degraded by 95.50%,and 90.06%.During composting at 55 °C and at added concentrations of 5 μg·g^(-1),OTC decreased rapidly,and the time required for50% and 90% degradation was 4.1 and 9.8 days,respectively;for TC,these values were 4.4 and 14.0 days,*** ef ficiencies for all TCs correlated well with moisture content of the *** results show that composting may be a practical and useful means to reduce concentrations of OTC and TC in swine manure prior to its land application.
