Discussion on the Biological Degradation of Acid/Basic Dyes
Dyes are widely used in textile field,resulting in the serious environmental pollution.Therefore,to investigate the textile wastewater treatment method is the need of green industrial production.We report the use of activated sludge bacteria,which is cheap and easy to be cultured,for biological degradation of dyes.The degree of dye degradation is characterized by cell toxicity,mouse systemic toxicity test,chemical oxygen demand,spectrophotometry and infrared analysis.The results show that the degradation of activated sludge on five kinds of dyes is effective,that is,after degradation,COD values from treated solutions decrease obviously,dye removal rate is 71.4%~76.1% and dye degradation average efficiency is 90.6%.
