超声波、电场和紫外光催化协同降解苯酚

Combinative degradation of phenol with ultrasound, electric field and ultraviolet photocatalysis.

在自制的多能场反应器中,以浓度为20mg/L的苯酚为对象,对物理能场作用于苯酚的降解效率和降解规律进行了初步研究.结果表明,单一超声波、电场、紫外光催化对苯酚的降解率很低,而三能场协同降解苯酚2h后最大降解率也只有32.59%.这表明苯酚是1种很难降解的有机物.在单一和组合物理能场反应器中加入H2O2后,降解率皆有不同程度的提高,其中三能场在2h后降解率几乎达到100%.

In the self-made reactor of multi-energy fields, degradation efficiency and rule of 20mg/L concentration of phenol by physical energy fields action were studied preliminarily. The phenol degradation rate of ultrosound, electric field and ultraviolet photocatalysis was very low; and the greatest degradation rate of phenol of three energy fields combined was only 32.59% after two hours. Phenol was a kind of organism very difficult to be degraded. But the degradation rate was enhanced in different degree after H2O2 was put into the single and combined physical energy field reactor, in which the degradation rate reached nearly 100% by three energy fields after two hours.
