| 摘 要： | 味精尾母液废水COD浓度极高同时含有大最氯离子.采用UASB反应器对味精尾母液废水进行处理,其中接种污泥来自啤酒厂UASB反应器.实验表明:当氯离子浓度在4 500 mg/L以下时,对厌氧微生物没有明礁的抑制作用;5 000 mg/L的氯离子浓度可以看作一个抑制限值,但经过驯化后,仍可获得较好的COD去除效果;当氯离子浓度达到8 000mg/L左右时,COD平均去除率在80%以上.

| Abstract: | A study of anaerobic treatment of fermentation mother liquid of monosodium L-glutamate with high chloride ion concentration was carried out using a laboratory-scale UASB reactor. The reactor was seeded with anaerobic sludge obtained from a UASB treating brewage wastewater. The results indicated that there was no evident inhibition performance when the chloride ion concentration was below 4 500 mg/L, while inhibition level obtained at a chloride ion concentration of 5 000 mg/L, however, a preferable COD removal rate could be achieved after acclimation. The average COD removal rate could be above 80% when the chloride ion concentration was as high as 8 000 mg/L. |
