摘要
研究了用厌氧发酵和光合菌（ＰｈｏｔｏｓｙｎｔｈｅｔｉｃＢａｃｔｅｒｉｕｍ，ＰＳＢ）协同处理尾叶桉（Ｅ．ｅｕｃａｌｙｐｔｕｓ）碱性亚硫酸钠法化机浆制浆废水的可行性。在厌氧段和光合菌处理段的容积负荷分别为８．５～１０．２ｇＣＯＤｃｒ／（Ｌ·ｄ）和１．２～２．１ｇＣＯＤｃｒ／（Ｌ·ｄ）时，连续运行２４ｄ后，全系统的ＣＯＤｃｒ、ＢＯＤ５、ＳＳ去除率分别达到５３％～５６％，７７％～８３％和８５％～８９％；系统对负荷的冲击有较强的耐受能力．ＧＣ／ＭＳ和１Ｈ－ＮＭＲ分析结果表明，废水中的木素衍生物降解明显；饱和和不饱和脂肪酸，完全能除去；苯甲酸、苯甲醛可完全去除。
The paper studied the biodegradability of effluent from E.eucalyptus SCMP by the combined treatments of anaerobic fermentation and photosynthetic bacteria(PSB).The removals of CODcr,BOD 5 and SS were 53%～56%,77%～83% and 85%～89% respectively at volume loads of 8 5～10 2 g CODcr/(L·d) ofr anaerobic fermentation and 1 2～2 1 g COD cr/(L·d) ofr PSB treatment.The process Performed well under higher or shock hydraulic loads.GC MS and 1H NMR analysis indicated that the lignin derivatives in the effluent can be degraded to a great extent,the unsaturated fat acids,saturatedfat acids,4 OH 3 OCH 3 benzonic acid and benzaldehyde can be removed completely,the linkages of OCH 3 to benzenic ring can be broken down during the biotreatment process.
