| 摘 要： | 试验采用A2/O生物膜工艺处理焦化废水,对A2/O处理焦化废水的工艺参数进行了优化研究。结果表明,在水力停留时间为39 h(其中:厌氧酸化6 h,缺氧反硝化10 h,好氧23 h),控制好氧段溶解氧质量浓度为3~6 mg/L,出水pH为6.8~8.0,混合液回流比R=3的情况下,可以得到良好的脱氮和除碳效果。

| Abstract: | An A~~2/O biofilm system was used to treat coke-plant wastewater.The technical parameters of the treatment were optimized.The optimum conditions for organic and nitrogen removal were as follows: the hydraulic retention time was 39 h(the anaerobic process 6 h,the anoxic process 10 h and the oxic process 23 h);the dissolved oxygen and the pH value in the aerobic reactor varied within 3~6 mg/L and 6.8~8.0,respectively;and the return sludge ratio of mixed liquor,R,was three. |
