| 中文摘要 |
| 硝酸盐在通过反硝化作用加速菌体生长的同时,对污泥中降解TA菌群的形成有进一步的诱导作用。经过6周的驯化其对TA的比降解能力达到18.75mg/(gVSS·d),而对照组为10.28mg/(gVSS·d).研究结果还显示,经过2-3周可以完成从反硝化作用到产甲烷作用的转化。 |
| 英文摘要 |
| Nitrate can promote the acclimatic process forterephthalic acid (TA) anaerobic degradation.Experiment results indicated that nitrate accelerated sludge growth by denitrification and at the same time,more microorganisms or groups degrading TA were induced and formed.After sixweek,the specific TA degradation rate reached 18.75 mg/(gVSS·d)and 10.28 mg/(gVSS·d)respectively by denitrify and methanogenic acclimation.The results also showed that it is possible to transfer TA degradation from denitrification to methane fermentation smoothly within 2-3 weeks. |
