摘要
应用超声波降解苯酚有机废水.结果表明,芳香族有机物苯酚易被超声释放到水中的自由基氧化,产生毒性小或易被生物降解的有机物中间体,并可进一步氧化分解成CO2与H2O等,从而使废水中有机碳下降,达到降解目的.加入无污染的强氧化剂(H2O2与O3等),将加快降解速度.
It is introduced that degradation of phenol wastewater by ultrasonic wave, and it is found that aromatic compound phenol is oxidized easily by radicals that is produced by acoustic wave in water, the phenol becomes organic medium compounds that are decomposed easily by microorganism or nature, finally it forms CO2 and H2O. The total of organic carbon decreases in waste_water. Degradation of phenol wastewater using ultrasonic wave is accelerated, if oxidant hydrogen peroxide is added into the wastewater.
