Abstract:

The reaction mechanism and treatment effect of treating dyeing wastewater by activated carbon from straw by sulfuric acid adsorption - oxidation method are introduced. It states that by using this preparation of activated carbon, the removal rates of the decoloration and COD_Cr effect are 100% and 98% respectively. By using activated carbon adsorption - oxidation method, the COD_Cr of wastewater could be reduced from about 1 632 mg/L to 32 mg/L.This method is cheap in cost, easy in operation, remarkable in treatment effect
