摘要
提取植物或动物纤维所产生的高浓有机废水,含短小纤维、木质素、纤维素、半纤维素、蜡质、果胶及其分解产物(糖、脂肪酸、醇等),较难生物处理,属含纤维素废水。试验研究和生产应用表明,生物水解对含纤维素废水中高分子有机物,可予分解并提高废水可生化性:在常温、pH约9.5时,水解池污泥浓度达6.5~16.0g/L,容积负荷达2.9kgCOD/m^3.d,COD去除率为24~36%,VFA提高3.9~5.1倍,BOD/COD提高12~16%。分析认为:中温、酸性,纤维素、木素含量低时,水解效果应更好。
Cellulosic wastewater from extracting staple is difficult to microchemic treatment. This paper stated the experimental and applying effect of microbial hydrolysis in the pulp black liquor treating, it was indicated that the removal rater of COD,MLSS and increment in VFA of hydrolysis to this effluent could be up to 24 - 36%,6. 5 - 16. 1g/1 and 3. 9-5. 1 as volume loading of microbial hydrolysis being 2. 9 kgCOD/m3,pH 9. 5,15 - 20℃.
