考察了超声波、微电解以及其联合作用对制浆造纸废水的处理效果,试验结果表明:微电解法单独处理速率较慢,在pH为4,铁炭质量比为10的条件下,反应120 min,COD_(Cr)的最大去除率仅为60.6%;在相同的处理条件下,超声强化微电解作用对处理制浆造纸废水有明显的协同效应,反应10 min,COD_(Cr)的去除率达90%以上,色度的去除率达97.3%,提高了去除率,缩短了处理时间.

고찰료초성파、미전해이급기연합작용대제장조지폐수적처리효과,시험결과표명:미전해법단독처리속솔교만,재pH위4,철탄질량비위10적조건하,반응120 min,COD_(Cr)적최대거제솔부위60.6%;재상동적처리조건하,초성강화미전해작용대처리제장조지폐수유명현적협동효응,반응10 min,COD_(Cr)적거제솔체90%이상,색도적거제솔체97.3%,제고료거제솔,축단료처리시간.
The effects of ultrasonic,micro-electrolysis,and the combination of them on pulpand paper industry wastewater treatment were studied,the experiment results showed:the microelectrolysis removing speed was slow,and its removing rate could merely achieved 60.6% when the pH was 4,iron to carbon ratio 10,and the reaction time 120 min;the ultrasonic enhanced microelectrolysis demonstrated an obvious synergy effects in the same condition,and its removal rate of COD_(Cr) and color were beyond 90% and 97.3% respectively when the reaction time was 10 min,which improve the treatment efficiency greatly and shorten the process time.
