A strain SDU10 was isolated from swine manure compost and identified as Pseudomonas stutzeri SDU10. It demonstrated excellent capability in NH-N removal. Optimal conditions of NH-N removal were determined, which were sodium acetate as the optimal carbon source, carbon to nitrogen (C/N) ratio of 10, temperature of 30 °C, pH of 7.0. Especially, P. stutzeri SDU10 could remove high concentration NH-N of 1500.0 and 2000.0 mg/l in 120 h with the NH-N removal rates of 91.1% and 61.6%, respectively. In batch experiments, the highest NH-N removal rate of 97.6% and chemical oxygen demand (COD) removal rate of 94.2% were obtained at initial C/N ratio 10 during piggery wastewater treatment using P. stutzeri SDU10. Results showed that P. stutzeri SDU10 had the potential for treatment of wastewater of high NH-N concentration.
一株分离自猪粪堆肥的菌株 SDU10 被鉴定为施氏假单胞菌 SDU10。它在 NH-N 去除方面表现出优异的能力。确定了 NH-N 去除的最佳条件，最佳碳源为乙酸钠，碳氮比（C/N）为 10，温度为 30°C，pH 值为 7.0。特别是，P. stutzeri SDU10 可以在 120 小时内去除 1500.0 和 2000.0mg/l 的高浓度 NH-N，去除率分别为 91.1%和 61.6%。在分批实验中，在处理猪场废水时，初始 C/N 比为 10 时，P. stutzeri SDU10 的 NH-N 去除率最高可达 97.6%，COD 去除率最高可达 94.2%。结果表明，P. stutzeri SDU10 具有处理高 NH-N 浓度废水的潜力。
