摘要：To develop microorganism technology for removing SO2 and NOx from flue gas, this study sieved out a strain of nitrate-reducing, sulfide-oxidizing Paracoccus sp. ZGL1 from activated sludge and analyzed its phylogenetic characteristics. The optimal initial pH for the growth and removal of substrate of this strain is 7.0; the optimal temperature is 30 degrees C; the optimal rotating table speed is 50 r/min; the optimal substrate concentration is 10 mmol/L; and the best concentration of carbon source is 10 mmol/L. A preliminary analysis on the law of transforming thiosulfate and nitrate-nitrogen in systems under aerobic and anaerobic conditions was conducted.
