摘　　要：探讨了用产酸微生物对化纤棉浆黑液进行产酸发酵,使其pH降低、部分COD水解并脱毒,在加入适量碳源的情况下提高其可生化性,通过实验最后确定出其最佳条件:在温度为32℃以上,种泥量充足,停留时间为2天左右,加入碳源占污染源COD量的40%的情况下,可使其pH由13降至8-9。The article researched microbial acidification ferment process of fibrous pulp of chemical fibre. In this process, the pHof fibrous pulp could be decressed, the part COD could be hydrolysed and be detoxin, and the biodegradability of it could be incressed after mixed some carbobydrates. Finally, we established that the best microbical acidication condition is: Tg≥32℃; retention period: 2days, the amout of mixed carbohydrate make up 40% of contaminant COD, the sludge amout is sufficient. In this conditions, the pHof fibrous pulp could be decreased from 13 to 8-9.
