Study on Decolorization for Dye Wastewater by adsorption-microwave degradation Activated Carbon from Bean Dregs
In order to improve the decolorization of dyeing wastewater,reduce the resources and energy consumption of the wastewater treatment process,Activated carbon from bean dregs (ACBD) was prepared the first time.The decolorizing effects of Methylene Blue on the activated carbon-microwave degradation were discussed.The decolorizing rate of dye-wastewaters respect on adsorbent time(t),adsorbent dosage(m) and pH value were investigated.And the conventional treatment results were compared.The results showed that microwave radiation could accelerate the adsorption of dye on carbon.Improve the decolorization rate and reduce the bleaching time.The decolorization rate reach to 98% after 10 seconds with 1.67g/L ACBD at pH=5.66 when 60mL for the 250mg/L dye wastewater.Compared with usual adsorption,conventional methods take 90min to reach the bleaching effect of microwave radiation just 10s under differently the quantity of ACBD.The decolorization time reduces greatly by microwave degradation.
