摘要：

采用新型膜电极——BDD薄膜电极, 运用电催化氧化方法处理DDNP生产废水, 考察了槽电压、极板间距、废水初始COD、电解质(NaCl)投加量等因素对废水降解效果的影响。研究发现, 槽电压和废水初始COD对COD去除率的影响最大, 而电解质的加入对电催化氧化影响不显著。此外对影响废水降解的主要因素进行了动力学分析。

Abstract:

The new type of film electrode(BDD thin film electrode) has been used for treating DDNP industrialwastewater by electro-catalytic oxidation process. The effects of influential factors, such as cell voltage, polar platedistance, initial COD of wastewater, dosage of electrolysis NaCl, etc., have been investigated. The results show thatcell voltage and initial COD of the wastewater have the biggest effect on the COD removal rate. But the effect ofelectrolysis on electro-catalytic oxidation is not remarkable. Then, kinetic analysis on the main factors of affectingwastewater degradation is carried out.

Key words: DDNP industrial wastewater, BDD thin film electrode, wastewater treatment, electro-catalytic oxidation
