摘要
首先研究了单一超声波场和单一紫外光催化场对模拟苯酚废水的处理 ,考察了超声波的频率、声强和紫外光照时间对处理苯酚的影响。最后研究了超声波 -光催化氧化协同处理苯酚的效果 ,研究表明 :双能场协同处理效果比单能场处理有较大提高 ,当超声波频率为20kHz,声强为0.44W/cm2,汞灯功率为160W ,反应时间120min时 ,苯酚降解率达35.11 % ,比单一能场提高约28%。
This paper at first studied the effect of disposal to simulated phenol with single ultrasound and photocatalysis,then sawabout the effect of frequency,ultrasound intension and illumination time on treatment of phenol,and at last studied the effect of sonophotocatalytic treatment,draw a con-clusion:when ultrasonic frequency is20kHz,ultrasound intension is0.44W/cm 2 ,mercury-arc lamp power is160W and reaction time is120min,the degradation rate is35.11%,28%higher than single energy field.
