白府菌对蔗渣浆CEH漂白废水的脱色 总被引:13,自引:0,他引:13
蔗渣硫酸盐浆CEH漂白废水的颜色主要自E段在导致毒性污染的同时,形成视觉污染。白腐菌是一类担子真菌,能降解植物组织的木素和变性木素和氯化木素,用白文化教育菌处理蔗渣CEH漂白废水,可明显降低其色度,而COD与BOD值下降了。吸附固定化白腐对废水的脱色能力更强一些,并可连续处理废水。 相似文献

固定化白腐菌对造纸废水的生物降解研究 总被引:6,自引:0,他引:6
就具有较强木质素降解能力的白腐菌对造纸废水的降解效果及条件进行了初步研究.分别采用固定化白腐菌和悬浮态白腐菌在不同接种量下对造纸废水进行降解,对降解过程中的白腐菌生长量、pH、COD、木质素含量等废水降解指标进行测定.结果显示两种不同状态下的白腐菌均能降解造纸废水,但它们的降解程度不同.其中固定化白腐菌降解木质素效果较好,且呈现较明显规律,说明固定化的白腐菌较悬浮态的白腐菌更具有降解造纸废水的潜在能力. 相似文献

采用两级生物强化的好氧工艺处理高盐难降解三元前驱体生产废水,考察了白腐菌和嗜盐单胞菌在高盐环境下处理低浓度COD和氨氮的去除效果。结果表明:一级好氧阶段投加嗜盐单胞菌能够将生化系统COD去除率由20%~26%提高到40%~60%。经过驯化的活性污泥对氨氮的去除率可达90%以上,氨氮的去除能力与投加的嗜盐单胞菌及白腐菌无关。二级好氧阶段投加白腐菌能够继续提升COD去除率10%~40%,而投加白腐菌和嗜盐单胞菌可使出水COD去除率继续提升40%~60%,两菌可相互协同强化生化处理效果,并使其出水稳定达到国家排放标准。因此,采用投加白腐菌和嗜盐单胞菌的生物强化技术可有效提升三元前驱体生产废水中难降解COD去除效果。 相似文献

A spent bleaching earth from an edible oil refinery has been regenerated by thermal processing followed by washing with a solution of hydrochloric acid. Optimal regeneration conditions have been controlled by decolorization tests of a degummed and neutralized crude edible oil. Optimal values (temperature: 500 °C, carbonization time: 1 h, HCl concentration: 1 M ) gave a material as efficient as a virgin bleaching earth. The percentage uptake of chlorophyll derivatives and β‐carotenoids calculated at 410 and 460 nm, are respectively 92.8 and 95% for an oil processed by the regenerated spent bleaching earth, against 77.4 and 92.7% for the same oil processed by a commercial virgin bleaching earth. The results obtained after decolorization of an edible oil with a regenerated spent bleaching earth indicate that during the process, the resultant oil did not undergo any changes in the iodine value, the free fatty acid content and the saponification value. © 2000 Society of Chemical Industry 相似文献

This study was purposed to explore the decolorization of dyes by fungi on either a soil or in a liquid medium and to determine the application through batch shaking system. Two commercial dyes were decolorized and studied with four fungal strains in three media. Fungal growth is the best in malt extract/glucose medium for all organisms. Decolorization of reactive blue 220 and methyl red was investigated in soil medium by Trametes versicolor. These dyes were removed 91% and 80% for methyl red and reactive blue 220 respectively(dye concentration; 100 mg·L~(-1)) by both organisms. Enzymatic activities were monitored. Laccase(Lac) and manganese peroxidase(Mn P) were detected. MnP enzyme had important role for the dye decolorization. This study demonstrates that it is possible to decolorize some synthetic dyes, which would be highly advanced for dye containing wastewater and soil. These applications could be used for dye bioremediation. 相似文献
