比较了几株白腐真菌在造纸黑液废水中的挂膜生长状况及其对黑液废水的处理效果 .结果表明 ,在 pH 6 .0的废水中添加葡萄糖 1.0 g/L ,酒石酸铵 0 .2 g/L及适量无机盐时 ,黄孢原毛平革菌 (Phanerochaetechrysosporium)和侧耳菌 (Pleurotusostieatus)以及本实验室自选的白腐真菌S2 2的挂膜状况和对黑液废水的处理效果最好 .废水中添加的葡萄糖和酒石酸铵的浓度分别为 1.0g/L和 0 .2 g/L时 ,侧耳菌的挂膜和对黑液废水的处理效果最佳 .S2 2菌在 pH10 .0时其木质素降解率和COD去除率最高 ,分别可达 84 %和 6 9% .黄孢原毛平革菌、侧耳菌和S2 2菌能够在碱性较强的废水中生长挂膜并显著降解木质素 ,表现出对废水很强的适应能力 .生物膜对黑液废水的半连续化处理结果表明了生物膜法的优越性 .图 8表 1参
Five different strains of white rot fungi were compared for their abilities of forming biofilm in pulp black liquor wastewater and their treatment effects on the treatment of the wastewater from paper making industries. A kind of porous plastic media was used to support the biofilm in the experiments. The results showed that Phanerochaete chrysosporium , Pleurotus ostieatus and S22 were best in forming biofilm and in treating wastewater when 1.0 g/L glucose and 0.2 g/L ammonium tartrate were added into the wastewater at pH 6.0. It was founded that the concentrations of carbon and nitrogen sources, and inorganic trace elements had great influences on the biofilm forming and wastewater treatment. The wastewater medium with 1.0 g/L glucose and 0.2 g/L ammonium tartrate showed the best treatment results using Pl. ostieatus . The highest lignin degradation efficiency (84%) and COD removal efficiency (69%) were achieved by S22 at pH 10.0. Ph. chrysosporium , Pl. ostieatus and S22 could grow in strong alkali effluent and degrade lignin effectively, which showed the stronger adaptability of these strains to the pulp black liquor. The results of semi continuous treatment of the wastewater suggested the superiority of biofilm to free mycelium. Fig 8, Tab 1, Ref 14
