| 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的比降能力达到１８．７５ｍｇ／（ｄＶＳＳ．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。

| Abstract: | 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. |
