摘要：用包含水解酸化、硝化和反硝化三个反应器的`组合式生物脱氮除碳系统处理尼龙6废水,着重分析了该系统的回流比,溶解氧.结果显示系统的最佳工艺参数为:回流比为3,反应器的溶解氧分别为0.5～1.0 mg・L-1、3.0～3.3 mg・L-1、1.8～2.3 mg・L-1、,同时CODCr和TN的去除率分别为95.85%、61.04%.Abstract：A combined system consisting of hydrolysis acidification, denitrification and nitrification reactors was used to removal carbon and nitrogen from the nylon-6 production wastewater. The effects of circumfluence ratio, and DO concentration on the system performance were analyzed. Results showed that when the circumfluence ratio was 3, DO of the hydrolysis acidification reactor, the first submerged biofilm reactor and the second submerged biofilm reactor were 0.5～1.0 mg・L-1, 3.0～3.3 mg・L-1 and 1.8～2.3 mg・L-1, respectively, the system performance was the optimal and CODcr and TN removal efficiency was up to 95.85% and 61.04%.作 者：刘国华 张曼 刘芳 陈季华 LIU Guo-hua ZHANG Man LIU Fang CHEN Ji-hua 作者单位：东华大学环境科学与工程学院,上海,51期 刊：中山大学学报(自然科学版) ISTICPKU Journal：ACTA SCIENTIARUM NATURALIUM UNIVERSITATIS SUNYATSENI年，卷(期)：,46(z1)分类号：X703关键词：尼龙6废水 回流比 溶解氧 脱氮除碳 Keywords：nylon-6 production wastewater circumfluence ratio DO removal of carbon and nitrogen
