【摘要】 实验对黄孢原毛平革菌和杂色云芝的染料废水脱色性能及其包埋技术进行了研究。分别确定了两种菌对酸性品红和亚甲基兰脱色的基本参数，筛选了适合杂色云芝的液体限氮培养基并确定了最佳接种量，研究了不同染料结构对真菌脱色的影响。实验结果表明：两种菌都能耐受一定浓度的染料，在脱色处理前利用低浓度易降解的染料进行诱导，处理效果从时间上来说是经济的，杂色云芝在pH=2.5～10.5比较宽的区间内保持了稳定的高脱色率，而且其适合用于间歇性染料废水的处理，这几点对于工程应用具有实际意义。对比评价了七种不同包埋体系的各项性能指标，并且运用正交试验优化了两种基本包埋体系的基础参数。初步摸索了两种菌在包埋条件下的不同特点，杂色云芝适合酸度低的固化条件，而黄孢原毛平革菌则更适应酸度高的固化条件。利用对实际废水的脱色验证了实验结论的有效性。更多还原

【Abstract】 The study on capability of decolorization of Phanerochaete chrysosporium and Trametes versicolor to dye wastewater and technology of embedment was carried out. The basic parameters of decolorization to Acid Fuchsin and Methylene blue using two kinds of white rot fungus were confirmed sepatately. The nitrogen limited medium adapting to Trametes versicolor was filtered and the optimal quantity of inoculation was ascertained. The effect on decolorization in accordance with different structure of dye was researched. These fungi can bear high concentration of dye to some extent. The effect of treatment is economical after decolorization in advance by dye of low concentration and high biodegradation according to time. Trametes versicolor has strong adaptability with pH of wastewater, holding stable high efficiency of decolorization in range of 2.5 to 10.5 according to pH . It suits to treat intermittent dye wastewater . These features above-mentioned have practical meaning in applying to engineering. The indexes of seven different kinds of system of embedment were compared and evaluated. In the meantime, the basic parameters of two kinds of elementary system of embedment were optimized. Different characteristics of two kinds of white rot fungus in embedment were groped for by experiments. Trametes versicolor adapts to low acidity in embedment, on the contrary, Phanerochaete chrysosporium adapts to high acidity. The vadility of conclusion was vadilated by decolorization of practical dye wastewater.更多还原
