电化学高级氧化技术处理难降解有机废水的影响因素

摘要

综述了实验研究和工程实践中有机污染物的初始浓度、p H值、反应温度、电解质等对该技术处理难降解有机污染物效率的影响,为电化学高级氧化技术高效处理实际工业废水提供指导;并提出了维持体系中H2O2的连续生成及电Fenton体系中低p H值与催化剂的固定等问题将是今后深入研究的重要方向.%The influences of the initial concentration of organic pollutants, pH value, reaction temperature and the electrolyte on the treatment of refractory organic pollutants in the experimental research and engineering practice are reviewed, which will provide guidance for the high effective application of electrochemical oxidation technology in treating real industrial wastewater.It is also suggested that the continuous generation of H2O2and the problem of low pH value and catalyst immobilization in the electrical Fenton system will be the important directions for further research.
