摘要：

采用光电催化氧化法降解季铵盐类杀菌剂十二烷基二甲基苄基氯化铵（1227）废水。以紫外灯为光源，DSA 电极为阳极，石墨电极为阴极，考察了阳极材料、光催化剂投加量、外加电场强度、极板间距、初始pH 对COD 去除率的影响。结果表明：光电催化氧化过程的最佳外加偏压为20 V，光催化剂最佳投加质量浓度为0.3 g/L，极板间距为0.5 cm，pH 为8.27，反应3 h 后1227 废水的COD 去除率可达到87%，TOC 去除率达到92%。光电催化氧化法的降解率高于单纯的光催化氧化和电催化氧化降解率之和，表现出一定的光电协同作用。降解后1227 的季铵盐、十二烷基长碳链及芳环结构均被破坏，有机物被充分地降解去除。

关键词: 光电催化氧化, TiO₂, 十二烷基二甲基苄基氯化铵

Abstract:

Photoelectrocatalytic oxidation process has been used for degrading wastewater containing dodecyl dimethyl benzyl ammonium chloride（1227）,using UV lamp as light source,DSA electrode as anode and graphite as cathode.The effects of anode materials,dosages of photocatalyst TiO₂,additional electrical field intensity,gap of electrodes and initial pH of the solution on the removal rate of COD are investigated.The results show that when the best additional voltage bias during the process of photoelectrocatalysis is 20 V,the optimal dosage of photoelectrocatalyst 0.3 g/L,the gap of electrodes 0.5 cm,pH 8.27,and reaction time 3 h,the COD removal rate of 1227 wastewater reaches 87% and TOC removal rate 92%.The results prove that the degradation efficiency of photoelectrocatalytic oxidation is higher than that of the simple summation of photocatalytic oxidation and electrocatalytic oxidation,showing a certain photoelectric synergetic effect.After the degradation,the 1227 wastewater quaternary ammonium salt structure,dodecyl long carbon chain structure and aromatic ring structure have all been destroyed，indicating that the organic substances are removed sufficiently by degradation.

Key words: photoelectrocatalytic, TiO₂, dodecyl dimethyl benzyl ammonium chloride
