Abstract

Abstract:

A fix-packed bed photocatalytic reactor has been designed. The photocatalytical degradation characteristics of the three kinds of biorefractory organic industrial wastewater from printing, dyeing, pharmacy and paper-making are investigated. The results show that the photocatalytic degradation of the COD_Cr of printing and dyeing and paper-making accord with zero grade reaction kinetics model, and the COD_Cr of pharmaceutical wastewater accords with complex reaction kinetics model. While 650 W UV irradiates for 240 min, BOD₅/COD_Cr of the three kinds of wastewater increase by more than 0.5.

Key words: photocatalytic reactor, photocatalysis, industrial wastewater, kinetics model

摘要：

设计了一种固定式填充复合床光催化反应器,在该反应器中,对印染、制药和造纸3种实际难降解有机工业废水的光催化降解特性进行了研究。研究结果表明:其对印染、造纸废水中COD_Cr的光催化降解符合零级反应动力学模式,而制药废水中COD_Cr的光催化降解存在着复杂的动力学模式;650W紫外光照240min,3种废水的BOD5/COD_Cr均提高到0.5以上。
