UASB+CASS+FENTON+BAF处理红霉素废水工程实例

Case study on the Treatment of Erythromycin Wastewater by UASB + CASS + FENTON + BAF

针对红霉素生产废水成分复杂、悬浮物（SS）含量高、有机物含量高、含有生物抑制性物质、生物降解性不好的特点,采用“UASB（上流式厌氧污泥床）＋CASS（循环式活性污泥法）＋FENTON氧化＋BAF（曝气生物滤池）”的组合工艺进行治理.调试运行结果表明,经该工艺处理后,废水COD由4500 ～ 5000mg/L降至30～40mg/L,氨氮（NH3-N）由300～ 500mg/L降至2～3mg/L,悬浮物（sS）由800～ 1000mg/L降至5～10mg/L,达到《山东省南水北调沿线水污染物综合排放标准》（DB37/599-2006）重点保护区修改单通知的排放标准.

Considering that the erythromycin wastewater contains complicated compositions, high concentrations of organic compounds and suspended solids （ SS）, and lots of pollutants difficult to degrade by microorganism, UASB （ Up - flow Anaerobic Sludge Bed） ＋ CASS （ Cycling Activated Sludge System） ＋ FENTON ＋ BAF （ Biological Aerated Filter） were applied to treat the wastewater. The COD of the effluent which has been treated by this process is decreased from 4500 - 5000mg/L to 30 -40mg/L, NH3 - N is deceased from 300 - 500mg/L to 2 - 3mg/L, SS is deceased from 800 - 1000mg/L to 5 - 10mg/L. The effluent water quality meets the Integrated Wastewater Discharge Standard revised for important protection districts of south- to- north water division project in Shandong province（ DB37/599 -2006）.
