【摘要】 探讨了用菌糠过滤处理染料溶液可行性。结果表明,菌糠对孔雀石绿、亚甲基蓝脱色率分别达到99%和96%以上,刚果红脱色率达到80%以上,溴酚蓝脱色率较低,在50%左右,混合染料溶液过滤不影响染料脱色。不同pH特性的染料溶液过滤后接近中性,菌糠对染料污染体系的pH有调节作用;菌糠过滤重复使用8次以上仍可保持相应的特性,初步说明菌糠过滤可以作为染料废水处理或预处理方法。更多还原

【Abstract】 The decoloring effect and feasibility to filtrate dyestuff and their mixture by pleurotus ostreatus culture was discussed. Results showed that the decoloring efficiency of malachite green, methylene blue and Congo red was more than 99%, 96% and 80% respectively while nearly 50% for bromophenol blue. The decoloring effect was not affected by mixing dyestuff solution. PH of the dyestuff solution could be regulated close to 7, and waste material from pleurotus ostreatus culture could be repeated used for 8 times, which indicated that filtration of pleurotus ostreatus culture could treat or pretreat dyestuff wastewater.更多还原
