【Abstract】 In this paper,a new method was developed for the treatment of crystal violet wastewater.The method involved the utilization of microwave radiation to the wastewater in the presence of activated carbon and air.The influences of several factors on the removal efficiency were studied in detail.From the experimental results,some important conclusions were obtained and presented as follow:(1)The pyrolysis and oxidation of crystal violet was raised by microwave radiation,with the addition of activated carbon and air conduce to the pyrolysis and oxidation could be intensified.(2)The removal rate of crystal violet was directly proportion to the power of microwave,radiation time,amount of activated carbon and initial concentration of crystal violet.(3)The removal rate could reach up to 99.6% under optimum conditions.The results suggested that the proposed method may be useful for the treatment of crystal violet wastewater.更多还原
