| 摘 要： | 采用SBR工艺处理焦化废水,探讨了pH值及碱度对有机物降解及生物脱氮的影响。试验结果表明,pH值8.5~9.2时,COD和NH3-N去除率均较高。出水NO2-积累,生物脱氮以短程硝化—反硝化的途径进行,NO2-对COD浓度的贡献值得重视。好氧反硝化脱氮约占总氮去除率的30.3%。

| Abstract: | SBR process was used to treat coking-plant wastewater in the paper.The effects of pH value and alkalinity on the removal of organic and biodenitrification were discussed.The experimental results indicated COD and NH3-N were removed effectively at pH value 8.5～9.2.NO2-accumulation indicated the short-cut nitrification-denitrification occurred in the biodenitrification.More attention should be paid to COD concentration in the effluent due to NO2-accumulation.The denitrification rate of the aerobic stage was a... |
