Abstract:

The mechanism of photocatalytic oxidation used for treating printing and dyeing wastewater is analyzed.The laws of the removal rates of COD and chromaticity changing with reaction time are analyzed, and at the same time, the influence of H2O2 dosage, pH of the wastewater and other factors are discussed.

Key words: photocatalytic oxidation, printing and dyeing wastewater, advanced treatment

摘要:

分析了光催化氧化处理印染废水的机理,通过试验,探讨了COD去除率和脱色率随反应时间的变化规律以及H2O2投加量、废水pH等因素对处理效果的影响.
