| 摘 要： | 利用经驯化的以嗜碱菌群为主的好氧活性污泥及常规厌氧、好氧污泥,针对不同浓度的棉浆黑液在现场进行了单独好氧及好氧-厌氧-好氧全流程工艺实验。结果表明:对棉浆黑液直接进行好氧曝气,可将原水pH值自12.4左右稳定降低至10以下,COD去除率可达40%左右。全流程实验中厌氧效果显著,pH值最低可降至8.2,整个系统抗冲击能力强,运行稳定,COD总去除率保持在63%以上。

| Abstract: | Utilizing acclimated aerobic sludge in which alkaliphilic microorganism was dominant and normal activated sludge,pilot tests on aerobic process individually and on the process of aerobic-anaerobic aerobic for different concentration black-liquor were operated.The results showed that: the pH value of black-liquor can be depressed from 12.4 to 10 steadily and COD removal rate was up to 40% by aerating directly.Through the entire process test,the effect of anaerobic acidification was remarkable,the lowest pH... |
