Sulfonamide antibiotics are widely used in human and veterinary medicine. In this study, we evaluated the factors involved in regulating the anaerobic degradation of sulfamethoxazole (SMX) in sewage and swine sludge. SMX concentration was determined in wastewater by a high-performance liquid chromatography equipped with a diode array detector. Our results showed that the degradation rate of SMX in the swine sludge was higher than in sewage sludge. Addition of different carbon sources (10 g/L) such as lactate, citrate, sucrose and glucose into swine feed, had significant effect on SMX degradation; and showed that sucrose addition yields a higher SMX degradation than the other additives. The higher sucrose concentration in sewage sludge and swine sludge, the higher hydrogen was produced. All the three of reactors could remove SMX with sucrose in swine and sewage sludge. Our study demonstrates a possible strategy for the effective treatment of swine and sewage sludge. The NGS technology was using to detect microbial change during experiment.
